## About The Pull Request
A weather anomaly can spawn on the station, causing a sandstorm,
snowstorm, or rainstorm to affect the room (and nearby rooms). These
weathers range from "harmless" to "mildly damaging".
They last for around five minutes.
The weather doesn't start immediately, giving people time to neutralize
it before it causes damage.
Neutralizing the anomaly stops the weather.
If they detonate, it just throw objects away from itself.

A rarer version of the anomaly can also occur, which brings a lightning
storm, which may damage the station itself.
Also, reactive weather armor. When you are hit, it summons a lightning
strike below nearby assailants.
## Why It's Good For The Game
With the added rain mechanics I wanted to use them, but it's kinda hard
to shoe them into the station because, "why is it raining on a space
station that makes no sense"
However, anomalies are weird, so this fits perfectly
## Changelog

add: Weather anomalies, in four variants: Rain, snow, sand, and the rare
lightning storm.

## About The Pull Request
##### Disclaimer - Some of the code/icons/sounds were ported from TMGC.
Introducing more weather types! And yes, you can now have rain be
reagent based!

<summary>Acid Rain</summary>

You can even make it rain ants, plasma, or drugs. All of their effects
get applied to turfs, objects, and mobs depending on the weather options
you select.
Did I mention... there is thunder?

Despite all this new stuff, none of it has been directly added to the
game but the code can be used in the future for:
- Wizard event - Similar to lava on floor, but this time make the
reagent random or picked from a list and give wizard immunity
- Chaplain ability - Maybe make this a benefit or ability once enough
favor has been obtained
- Admin events - I have added a BUNCH of admin tooling to run customized
weather events that let you control a lot of options
- New station maps/biomes for downstreams (Jungle Station, etc.)
- Change Ion storms to use the new weather system that triggers
EMP/thunder effects across the station
- IceBox could get plasma rain
- Lavaland could get thunder effects applied to ash storms
Relevant PRs that removed/added some of the weather stuff I used:
- #60303
- #25222

The original `siren.ogg` sound used on a lot of SS13 servers doesn't
seem to have any attribution that I could locate. The sound was added
about 15 years ago. So I just looked for a somewhat similar sounding
siren noise on Freesound.
## Why It's Good For The Game
More weather customization!
## Changelog
🆑
add: Added new weather types for rain and sandstorms. Rain now uses a
reagent that gets exposed to the turfs, mobs, and objects. There is also
a thunder strike setting you can apply to any weather.
add: Hydro trays and soil will now add reagents to their trays when
exposed to a chemical reaction. (weather, shower, chem spills, foam
grenades, etc.)
add: Weather temperature now affects weather reagents and mobs body
temperature.
bal: Snowstorm temperature calculations were tweaked to allow universal
weather temperature effects.
sound: Added weather sounds from TGMC for rain and sirens (attributed to
Cuboos and IFartInUrGeneralDirection )
image: Added weather images from TGMC for rain and sand storms
(attributed to Novaepee and Bimmer)
refactor: Refactored a lot of the weather code to be more robust
admin: Admins can now control more weather related options when running
weather events. The weather admin verbs have been moved to their own
"Weather" category under the Admin tab.
