ExtremeWeather 1.7.1

New
- Every weather event (blizzard, hurricane, monsoon, heat wave, cold snap, sandstorm, tornado) now shows an on-screen and chat warning ~30 seconds before it starts.

Balance
- Default event chances lowered: blizzard 3% → 1%, monsoon 3% → 1%, hurricane 1% → 0.5% per game day.
- The hurricane chance setting on the world Customize screen is now a dropdown: off / 0.5% (default) / 1% / 2% / 5% / 10%. Existing worlds keep their configured values.
- Tornadoes now only occur during hurricane and monsoon events: 20% chance every 5 minutes while the event is active. They no longer spawn from ordinary warm storms.
- Tornadoes last longer: 60–400 seconds depending on strength (was ~20–65). Configurable via TornadoMinDuration / TornadoMaxDuration.
- Animal shelter AI is now off by default and marked experimental ("Animals seek shelter (experimental)"). It can be enabled on the Customize screen or via AnimalsSeekShelter in the config.

Fixes
- Rain no longer falls through roofs when particles drift in under eaves, overhangs, or through openings. (Some modded roof blocks, e.g. VS Roofing, may still leak, fix planned.)
- Snow no longer destroys waterwheels, axles, or other machinery placed in flowing water.
- Running water freezing into snow blocks is now off by default (RunningWaterFreezesToSnow). Streams keep flowing in deep cold unless you opt in.

Server performance
- All snow/weather load-tuning settings now appear in ModConfig/extremeweather.json and can be tuned by server admins.
- New adaptive throttle: snow processing scales itself down when a pass exceeds SnowMaxTickMillis (default 8 ms).
- The canopy snow-strip sweep is spread across ticks instead of running in one burst.

Changelog — 1.7.0

New: Tornado

A rare wandering funnel that touches down during severe warm storms.
- A real mesh-and-shader funnel that grows in on touchdown and thins away as it lifts.
- Rips a path across the land, scours grass to bare soil, tears out foliage, and picks up & drops loose items (rocks, sticks, etc.); stronger funnels chew at structures near the core.
- Sweeps up exposed players, animals and items, they orbit up the funnel and are flung; shelter (walls / underground) is safety.
- Warning cues as it approaches: a deep roar and sub-bass rumble, a mounting screen tremor, and a darkening sky with dust haze (thickness varies per storm).
- Spawn/test with /exwevent tornado, or /exwtornado <size> (size up to 5× for a monster).

New: Sandstorm

A hot, dry desert storm.
- Near-zero visibility behind a thick orange-brown dust haze under a darkened sky, driven by strong dry wind.
- Blowing dust that now collides with terrain (won't blow through walls).
- Exposed players suffer abrasion/choking damage and slowed movement; animals are battered too; crops in the open get withered. Shelter is safe.
- Its own audio, swelling as it hits and muffled indoors. Occurs naturally in desert biomes, or force it with /exwevent sandstorm.

Fixed

- Major server-lag fix: on large or heavily-modded worlds the snow system's world-wide background pass (and the deep-cold water-freeze sweep) could stall server ticks for seconds while snow was active. Both are now hard-capped per tick regardless of how many chunks are loaded.

Config

- New options for both events (enable, chance, damage) plus tornado size scale, all respecting the danger-level setting.

Extreme Weather 1.6.3

Fixes
- Fixed a crash when connecting to a multiplayer server running this mod (Don't know how to instantiate collectible behavior of class 'ExwStickyFalling'). Affected multiplayer clients only; singleplayer was never impacted.
- Fixed the server hitching in snowy areas, noticeable as a delay before broken blocks drop their items while mining. Snow processing is now spread smoothly across time instead of running in one heavy burst every few seconds. Same snow behavior, no more periodic stalls.

Extreme Weather 1.6.2

Performance
- Major fix for servers freezing during snowfall, especially on heavily-modded packs. The snow system was re-reading climate data for every column it processed each tick, an operation that gets more expensive the more mods are installed, causing multi-second server stalls whenever snow accumulated or melted. Climate is now sampled once per chunk and reused, cutting the work by hundreds of times with no visible difference in normal play.

Fixes
- Fixed the "seek shelter" animal AI failing to attach (spamming the server log with errors on every animal). Animals now correctly seek shelter during storms again.

Extreme Weather 1.6.1

New
- Fires, torches and other lit heat sources now melt the snow around them — faster the closer — carving a natural slope down toward the warmth in snowy landscapes.

Fixes
- Snow no longer piles up on torches or torches in holders.

Admin / salvage commands (require the controlserver privilege)
- /exw snow off — halts the entire snow system (accumulation, melt, and the world-wide chunk checks) so a save overwhelmed by deep snow runs light. /exw snow on resumes; the setting persists across reloads.
- /exw clearsnow [radius] — instantly removes all mod snow (snow blocks, layers, and snowy roofs/plants) within a radius around you (default 64, max 128). Intended for cleaning up before removing the mod, so leftover snow doesn't burden the world afterward.

Extreme Weather 1.6.0 — Compatibility Update

Extreme Weather now focuses purely on the weather and its effects on the world
Recommended companion: Immersive Body Temperature, compatibility should full, any issues that come up should be easily fixed

Removed (should be completed using other mods)
- Wind chill (body-heat drain in cold wind)
- Fire warming (body-heat gain near heat sources)
- The entire wetness system: soaked state after swimming, drying, wet movement slowdown, wet cold damage
- All clothing weather protection (wind and wet resistance) and the Weather Protection character panel
- The mod no longer touches body temperature, the wetness attribute, or clothing stats in any way

Removed (design)
- Random flying-debris damage to players and animals during hurricanes

Kept
- Swimming in freezing water still deals heavy damage while you're in it (no lingering effect once you're out)
- Heat stroke from sun exposure during heat waves

For mod developers
- Weather events now also mirror their precipitation into ClimateCondition.Rainfall on current-value reads — mods reading climate, wind, or rainfall automatically see this mod's weather without integration code

Extreme Weather 1.5.2

Fixes
- Fixed all world Customize screen options showing internal names (worldattribute-...) for everyone who installed the mod as a downloaded zip — this had silently affected zip installs in every previous release
- Fixed snow accumulation ignoring snowfall produced by weather patterns and storm events — snow buildup now matches what you actually see falling (this was the long-standing "snow only accumulates during blizzards" issue; it depended on local climate, not on world age)

Extreme Weather 1.5.1

New: Natural weather events
- Daily event chances configurable per event (world Customize screen + config file)
- New worlds: 2 calm days before the first event can occur
- Admin command: /exwevent status|<event>|stop

Balance
- Extreme wind now comes only from events — vanilla storms capped below all damage thresholds (fixes block damage and player-shoving in strong vanilla weather)
- New worlds default to non-destructive weather: block destruction, crop damage and player damage are opt-in (existing worlds unchanged)
- Elemental danger levels: Off / Low / Medium / High (Low is new: half damage)
- Wind strips canopy snow at wind > 0.5 (was 0.75)

Config
- Customize screen simplified: 16 options instead of 29, tooltips on all of them
- New: "Mod sounds" toggle + "Mod volume" slider (all mod audio)
- Removed niche options from the screen; still available in the config file

Fixes
- Thatch and sod roofs no longer converted into snow blocks by deep snow
- Storm/wind audio fades in and out smoothly with gusts
- Blizzard audio now always plays during whiteouts, scaled by wind
- Elemental danger dropdown showed internal key names

Removed
- /exw snow, /exw blizzard, /exw clearweather, /exw lightning (replaced by /exwevent)

Extreme Weathers v1.5.0

• Changed all modded weather phenomena to events instead of ambient, giving better control, easier patchability and easier configuration.
• Optimization fixes
• Balancing fixes

Extreme Weather 1.4.4

Fixes

- Fixed deep snow destroying roofs, fences, slabs, stairs and other snow-coverable blocks. Blocks with a snowy look (sloped and ridged roofing of any material, fences, gates, slabs, stairs, beams) were first correctly whitened by falling snow, then mistaken by the snowpack logic for a fully buried plant and replaced outright with a snow block. All of these now shed their misidentification: snow whitens them and rests on top, never consumes them. Note: blocks already destroyed in existing worlds can't be restored, the snow block doesn't remember what it replaced. Sorry to everyone who lost a roof!
- Hot springs now keep their surroundings snow-free. Snow no longer accumulates anywhere near boiling water (the geothermal halo where the colorful bacteria mats grow), and snow that already piled up there — or drifts in — melts away on its own during subsequent snowfalls.

Extreme Weather 1.4.3

Fixes

- Fixed violent screen shaking after unpausing in singleplayer. Pausing during storm-force winds caused camera shake (and wind push) to build up behind the pause menu and discharge all at once on unpause — the longer the pause, the worse the shaking. Weather forces now stop entirely while the game is paused.
- Fish are no longer harmed by weather. Fish swimming at the water surface were being struck by hurricane flying debris. All aquatic creatures (including modded ones) are now fully exempt from weather effects: flying debris, wind shove, heat stress, and avalanches — and they no longer try to seek shelter from storms.

Extreme Weather 1.4.2

Tweaks

Freezing water is now merciful until minus 10. The deadly water peril (damage and body-heat crash while swimming) now starts at -10 C instead of 0. Cold autumn water soaks and chills you, but only genuinely arctic water kills. Existing installs adopt the new threshold automatically.

Bugfixes

Fixed snow buildup (and all other precipitation-driven effects) barely working during natural weather. The mod was reading only the storm-event component of precipitation, which is near zero for ordinary climate rain and snow, so effects mostly appeared only when precipitation was set by command.

Fixed hurricanes tearing out iron doors and iron hatches. Metal doors and trapdoors are now immune to storm breakage and no longer rattle. Iron holds.

Fixed freezing water dealing damage in enclosed spaces. The peril now requires open sky overhead, so indoor pools, baths and cellar water are safe.

Extreme Weather 1.4.1

New features

New mod icon.

Repair command for time accidents. /time speed mishaps could leave the weather simulation and the mod's snow clocks scrambled, causing stuttering storm sounds and runaway snow catch-up. The new admin command /exw fixclocks repairs the mod's side; /weather setw still resets the vanilla side.

Tweaks

All chat messages removed. The mod no longer prints storm or heat warnings to chat. The world itself is the warning: darkening skies ahead of storms, the rising howl of the wind, rattling windows.

Rainbows and auroras removed.

Frozen doors removed. Doors no longer freeze shut in deep cold; the feature may return in better form later.

Bugfixes

Fixed grass and foliage refusing to be buried by deep snow, leaving unnatural green holes in the snowpack. Plants now frost over through all of vanilla's snow stages and are cleanly swallowed by the drift once their cover is full or the pack reaches them. The root cause: snow-dusted plants change block material, which made them invisible to the burial logic.

Fixed snow blocks being placed on top of living grass instead of replacing it.

Fixed hurricanes toppling player-placed logs. Only naturally grown trees topple now; log cabins and timber builds are safe.

Extreme Weather 1.4.0

New features

Avalanches. Steep, heavily snow-laden slopes can let go, especially in storm winds. A powder wave roars downhill with a deep rumble, strips the slope, and buries the runout in deep snow. Anyone caught takes heavy damage, is swept downhill and buried where they land. Rare, loud, and worth respecting.

Rainbows. When a real rain clears in daylight, a rainbow arcs opposite the sun for a few minutes. It only appears while the sun is low, just like the real thing.

Auroras. Clear nights in deeply cold climates now bring softly drifting, gently pulsing northern lights.

Snow-dusted plants. Grass and similar foliage now frost over progressively through all of vanilla's snow stages as snow falls, instead of staying green until buried. Once a plant is walled in by full snow blocks on all four sides, it is replaced by snow outright. Everything returns with the thaw.

Configure absolutely everything. The world creation screen now has individual switches for every single feature, 37 settings in total. Want only the deep snow buildup and nothing else from this mod? Turn the rest off.

Tweaks

True hurricanes. Extreme weather is now driven by a dedicated Hurricane wind pattern: rare, stronger than any vanilla storm, and lasting up to a full day. All of the mod's dramatic effects, from rattling windows to flying debris to wind shove, now require hurricane-strength wind that vanilla storms cannot reach. When the house starts shaking, it means something.

Monsoon fury. Plank rotting, indoor rain drumming, the whiteout and crop flattening now require rain at full intensity. Ordinary rain is just rain; a true downpour is an event.

Blizzard peaks bury. Snow buildup still scales with precipitation, but a storm at full fury now dumps snow at double rate on top of that, twenty times faster than a light snowfall.

An honest storm warning. The wind warning now only triggers for genuine incoming hurricanes, never for ordinary storms.

Storm sounds follow the wind. Blizzard and hurricane soundscapes are now driven purely by wind strength, so a dry gale howls correctly even without snowfall.

Bugfixes

Fixed melting leaving frost on partially snow-covered plants.
Fixed snow deposits stopping in columns where foliage had been dusted with snow.

Extreme Weather 1.3.0

New features

Animals seek shelter. Creatures caught in blizzards, monsoons or hurricanes now look for a roofed spot nearby and head for cover. Give your livestock a barn and they will use it.

Storms affect animals. Hurricane wind shoves exposed creatures, flying debris injures them, and animals left in the sun during heat waves suffer heat stress. Shade and shelter protect them.

Doors freeze shut. In deep cold (below -5C), wind-exposed exterior doors freeze in their frames and take a few determined attempts to crack open. Frozen doors are visibly frosted over. Doors inside buildings never freeze.

Visible breath. Players exhale little puffs of fog in freezing air.

Clothing wind resistance. Every worn piece now blocks part of the wind chill based on its warmth, material and condition. Furs are the best windbreakers, leather close behind, linen barely helps. A full fur set in good repair stops wind chill completely.

Clothing wet resistance. Clothing also slows down rain soaking, with leather the best at shedding water. Swimming soaks you instantly no matter what you wear.

Food fights the cold. A full food bar negates up to half of all body-heat drain, scaling down as you go hungry. Eat well before braving the winter.

Weather Protection panel. The character screen now shows your outfit's current wind and wet resistance next to the Stats panel, updating live as you change clothes.

Storm warnings. A chat message warns you when the wind is climbing toward hurricane strength, and when a heat wave sets in.

Camera shake setting. The gust rumble during hurricanes can now be tuned or disabled per player (CameraShakeStrength in the config).

Tweaks

Wind chill heavily rebalanced. The old drain could freeze an unclothed player in seconds and made cold-climate starts nearly impossible. The new default is roughly a quarter as harsh, and everyone gets it automatically on update.

Wind chill intensity slider. A new world-creation setting from 0 to 300 percent, with 0 disabling wind chill entirely.

Blizzard fog and camera effects split. The whiteout fog now stays at full strength when you shelter indoors, so the storm still rages when you look out a window. Only the frost vignette on your vision fades under cover.

1.2.2 — Icicles no longer grow on interior ceilings; undersides must face outside air.

1.2.1 — Server config now properly applies to all connecting players (wind shove and other client-side effects previously used each player's local settings)

Extreme Weather 1.2.0

New features

Weather Variety included. The weather pattern pack (drizzle, sun showers, squalls, fog banks, dust storms, new winds and storm events) is now part of this mod. 

Door rattling. Doors and trapdoors exposed to hurricane wind rattle in their frames, with sound, dust and real physical shaking of the door itself. Doors inside buildings or underground stay quiet.

Door breakage. Exposed doors can be ripped out by hurricane wind. Half of the time the door is not lost but wrecked in place, turning into a ruined door that keeps its position and hinge side.

Window rattling. Glass panes exposed to storm wind rattle constantly, speeding up and slowing down as gusts hit, with rattling sounds. All panes of a connected window shake together as one.

Window breakage. Windows now break as whole structures. When the wind takes one pane, each connected pane has a fifty percent chance of shattering with it. Windows attached to nothing are destroyed instantly.

Flying glass. Standing within three blocks of a shattering window causes cuts and damage.

Roof destruction upgrades. Torn roofing bursts into debris particles blown downwind. Roof pieces left floating with no attachment are swept away instantly.

Wood rubble. Destroyed roof tiles, rotted planks and collapsed roofs drop wooden rubble that falls straight down and lands on the first surface below, crushing grass where it lands. Rubble crumbles if the block under it is removed.

Plank rot. Sustained rain now decays planks through their full chain. Normal planks become aged, then very aged, then fall apart. Ebony becomes aged ebony, then rotten ebony, then falls apart. Acacia becomes aged acacia, then falls apart.

Snow weight. More than three stacked snow blocks crush plank or dirt roofs that have nothing supporting them from below. Build proper roof tiles in snowy climates or winter comes inside.

Flames blown out. Lit torches and firepits exposed to hurricane wind are snuffed out, just like in rain.

Indoor rain sound. When it rains and you are sheltered inside a buildingon the roof, louder the heavier the rain. Caves stay silent.

House sounds. Sheltering indoors during high wind surrounds you with creaking timbers and groaning wood.

Icicle behavior. Icicles shatter when the block they hang from is removed, cannot be placed floating, and are now available as a buildable block in creative mode.

Improvements

Storm sounds now build up gradually over several seconds of sustained wind instead of cutting in and out during short gusts.

New sound effects throughout: glass shattering, doors breaking, roofs tearing, trees falling, window and door rattles.

Tree falls are louder and toppled trees leave more stick debris.

Block destruction and crop damage are now separate general settings, so you can have harmless storms or protected farms, both in the config file and at world creation.

## Extreme Weather 1.1.0

### New features
- **Heat waves** — in scorching climates (33°C+), direct sun exposure builds toward
heat stroke: periodic damage and a pulsing heat filter over your vision. Find
shade for slow relief or take a dip in water to cool off fast. Farmland bakes
dry rapidly during a heat wave, and crops on dry farmland wither — keep them
watered or shaded.
- **Freezing water peril** — falling into water in sub-zero weather is now a death
sentence: heavy damage while immersed and a crash in body temperature. Climbing
out leaves you soaked — slowed and losing health in the cold until you dry off:
~90 seconds in the open air, ~10 seconds beside a fire.
- **Rapid fire warming** — standing near a lit firepit, forge or oven now warms
your body temperature quickly (and dries wet clothes). Fires are true sanctuaries.

### Improvements & fixes
- Switched to compiled-DLL packaging: faster world loading, better crash diagnostics
- Simplified configuration file
- A hand-edited config with a JSON mistake is no longer overwritten with defaults
- Fixed hurricane wind shattering fully indoor glass (windows in interior walls,
display cases); only wind-exposed glass breaks now
- Fixed the "Deadly" danger setting potentially applying its multipliers twice
- Fixed heat filter and close-lightning whiteout not appearing with certain
visual-effect combinations
- Plank weathering and storm crop damage rates corrected on multiplayer servers
- Reduced log spam
