Weather's Rumble Add-on for Minecraft

Weather’s Rumble transforms Minecraft Bedrock into a world with living, changing and dangerous weather. Instead of simple global rain and flat clouds, weather develops regionally using simulated temperature, humidity, pressure, dew point, wind, instability, CAPE, wind shear and storm potential. Clouds form, grow, move, develop into storms and eventually dissipate.

DYNAMIC 3D CLOUDS

The add-on replaces ordinary flat clouds with large 3D cloud formations built from many individual cloud pieces.

Cloud types include:

• Cirrus
• Stratus
• Cumulus
• Towering cumulus
• Cumulonimbus
• Nimbostratus
• Storm anvils
• Scud clouds
• Wall clouds
• Mesocyclones
• Funnel clouds
• Hurricane rainbands and eyewalls

Clouds can appear white, cool blue-gray, light gray, dark storm gray, peach, pink or purple depending on the atmosphere and time of day.

Clouds are rendered using multiple detail modes so weaker devices can reduce the amount of visible cloud detail.

REALISTIC WEATHER

Possible conditions include:

• Clear skies
• Partly cloudy weather
• Overcast skies
• Fog
• Drizzle
• Rain
• Thunderstorms
• Snow
• Sleet
• Hail
• Blizzards
• Hurricanes
• Flooding
• Wildfires

Rain and snow appear below their clouds instead of covering the entire world. Storms can produce lightning, stronger wind, reduced visibility, dark cloud bases and changing precipitation intensity.

TORNADOES

Powerful thunderstorms can form rotating mesocyclones, wall clouds and tornadoes.

Tornado shapes include:

• Rope
• Needle
• Drill-bit
• Cone
• Stovepipe
• Wedge
• Elephant trunk
• Multiple-vortex tornadoes

Tornadoes can strengthen, weaken, change shape, bend with storm motion and grow downward before touching the ground.

Their visible width, wind field, mesocyclone and subvortices scale together. Wide tornadoes have wider rotating cloud bases and multiple vortices spread throughout the main circulation.

Tornadoes can:

• Pull players and mobs into the circulation
• Carry rotating block debris
• Strip grass and vegetation
• Turn exposed soil into dirt, coarse dirt or podzol
• Dig into the ground during extreme winds
• Break structures based on their materials
• Remove roofs and exposed walls first
• Throw debris outward when weakening
• Restore some falling debris as blocks after landing

Exact tornado wind speeds can be selected up to 1,000 mph.

Examples:

/weather:tornado ef5 100ft wedge 300mph
/weather:tornado_mph 700 180ft multiple_vortex

STRUCTURAL DAMAGE

Blocks use different wind-resistance values based on their material.

Leaves, glass, wood, brick, cobblestone, concrete, stone, deepslate, metal and other materials do not all fail at the same wind speed.

Embedded rebar provides a moderate strength increase, but it is not indestructible. Rebar bends and loses strength after repeated or extreme wind loading.

Block debris uses matching side, top and bottom textures. Logs preserve their end-grain direction, and colored blocks keep their correct colors while flying through the tornado.

HURRICANES

Hurricanes form over supported warm-ocean regions and weaken after moving over land or colder water.

They include:

• Large spiral rainbands
• A clear central eye
• A rotating eyewall
• Embedded thunderstorms
• Strong surface wind
• Heavy rain
• Flooding
• Structural wind damage
• Gradual landfall weakening

The hurricane renderer uses distance-based detail, shared particle limits and timed visual updates to reduce lag while keeping the storm large.

FLOODING AND SANDBAGS

Heavy rain and tropical systems can create localized flooding.

Sandbag blocks create a protected area that prevents simulated flood water within a 10-block horizontal radius. Protected doors will not leak flood water into buildings.

WILDFIRES

Dry conditions, lightning and player-created fires can start wildfires.

Wildfires can:

• Spread across flammable terrain
• Leave ash and scorched ground
• Produce smoke
• Reduce visibility
• Spread embers with the wind
• Create new fires away from the original fire front
• Be weakened or extinguished by rain

WEATHER TECHNOLOGY

The add-on includes several tools for observing and surviving dangerous weather:

Doppler Weather Radar

Radar modes can display:

• Reflectivity
• Velocity
• Rotation
• Precipitation
• Echo-top height
• Lightning
• Storm development
• Severe-weather detection
• Projected storm tracks

Weather Map

The regional map can display:

• Temperature
• Pressure
• CAPE
• Humidity
• Dew point
• Wind
• Cloud cover
• Precipitation
• Weather types
• Regional weather patterns

Forecast Station

Displays a three-day forecast based on the simulated atmosphere around the station.

Wind and Storm Meter

Measures surface wind, upper-level wind, wind shear, CAPE, lapse rate, storm potential and nearby tornado conditions.

Severe Weather Siren

Automatically detects nearby dangerous storms and can issue:

• Severe-thunderstorm alerts
• Tornado watches
• Funnel warnings
• Tornado warnings
• All-clear messages

Tornado Tracker

Displays tornado strength, exact wind speed, distance, direction, position, movement, development phase and projected track.

Local Season Controller

Changes the season within a selected region. Seasons influence temperature, humidity, snow, storm development, cloud growth and forecasts.

GRAPHICS MODES

The Settings Block includes several graphics options:

• Performance
• Balanced
• Enhanced
• Visual
• Cinematic

Performance Mode reduces rendering for weaker devices.

Enhanced Mode provides detailed clouds without requiring Vibrant Visuals.

Visual and Cinematic modes provide the greatest cloud and storm detail.

REQUIRED SETTINGS

TURN ON:

• Beta APIs
• Upcoming Creator Features

The add-on may not function correctly without these experiments enabled.

Weather’s Rumble is still being developed. New weather systems, improved visuals, performance updates and bug fixes will continue to be added.
