Weather Event
Weather Events are a gameplay mechanic introduced in "The Fog From Flathill" 0.8.2 Update in Abiotic Factor. It causes the entire GATE Cascade Research Facility to experience certain weather phenomena.
Players have to deal with or endure the weather phenomena such as lowered vision due to fog, ambient radiation and hazardous spores.
Several items can be worn to prolong a players survivability when exposed to the events.
For radiation a 
Hazardous Materials Suit, 
Rat Suit or a 
Lead Vest / 
Radiation Vest can be worn.
For airborne spores a 
Lab Mask, 
Mushroom Helmet or 
Carapace Helm can be worn, or alternatively a full body suit like Hazardous Materials Suit and Rat Suit.
Gameplay
An announcement will be heard right before a Weather Event is triggered, always at 7 AM on a given day.
Weather Events last for a full day, ending at 7 AM the following day. The Fog Phenomenon and Radiation Leak events can be terminated earlier by activating a Terminate Weather Event button within the Facility.
Once a Weather Event ends, another one cannot occur for the next four days. After that, there is a 20% chance that a Weather Event will occur at 7 AM.
Fog Phenomenon
The entire facility is engulfed by a thick fog. Unlike in Flathill, the fog much is more concentrated, further decreasing visibility and causing navigation to be extremely difficult. During this event, Symphonists will appear in the Facility. And Composers will spawn only in Reactors.
Eating 
Fogiri introduces a 50% chance for a Fog Phenomenon to start at 7 AM the next day, or the same day if it's in the morning before that time.
Terminate Fog
The Terminate Weather Event: Fog button can be found near the entrance to the Flathill portal room on the third floor of the Offices Sector. The blue button is located on a console to the right of the keypad. Activating the button will vent the fog immediately and end the event.
Radiation Leak
Introduces ambient radiation of 0.25 r/sec, accompanied by green fog.
Terminate Radiation Leak
The Terminate Weather Event: Radiation Leak button can be found in a room overlooking the irradiated area in Manufacturing West. From The Blacksmith, turn left, run up the road and look left for the sign "Control Tower". Several soldiers are guarding this area (usually two Grunts, a Medic, and a Captain). Once you're inside, you'll find a blue button on the right from a Dr Manse hologram. Activating the button will vent the radiation and immediately end the weather event.
An additional button for terminating the Radiation Leak event can be found on the main control panel for the Cloud Reactor in Reactors.
Airborne Spores
The facility is engulfed in an orange haze with spores in the air, much like the weather in The Mycofields. The ambient temperature in most sectors is raised to 80°. Mushroom Peccaries will spawn in the place of normal Peccaries throughout the facility and the player has a chance to receive the Spore Infection debuff if not wearing a piece of gear that provides the Airtight Seal buff.
Terminate Airborne Spores
The Terminate Weather Event: Airborne Spores button can be found in Reactors in the Mist Reactor section in the control room.
