How we know
One source: Hydrometcenter of Russia. Not yet confirmed by a second, independent source.
Our own score for this event is 37 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v5. Rows carrying other versions were judged by different rules and are not directly comparable.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.

Safety information
What to do in dense fog
First three things, then what to do before, during and after. From the US National Weather Service’s fog safety pages.
For this reportSevere Weather · Simferopol
Slow down, low beams on
Slow down and leave plenty of room to the vehicle ahead. Use low-beam headlights, and fog lights if you have them, so your tail lights are on too. Never high beams: their glare makes it harder to see.
NWSIf you cannot see, get off the road
Turn on your hazard lights and pull into a safe place, such as a car park. If there is none, pull as far off the road as you can, keep only the hazard lights on and take your foot off the brake, so no one follows your lights into you.
NWSOn the water, slow down and listen
Turn on all your running lights, listen for other boats and for fog horns, and keep out of shipping lanes: large ships cannot see you.
NWS
Before, during, after. Here it is “after”.
Before · When fog is forecast
Allow extra time
You will need to drive more slowly than usual.
On a boat, know where you are
A compass, GPS or a chart, and radar if you have it.
US National Weather Service
During · In the fog
Follow the lines
Keep your eyes on the road markings to stay in your lane.
Keep your distance
Leave room for sudden stops and changes in the traffic.
Lost on the water
If you cannot get your bearings, stay put in a safe place until the fog lifts.
US National Weather Service
After · When it lifts
Below freezing, watch for ice
Freezing fog leaves a thin, almost invisible layer of ice on roads, steps and pavements. Drive more slowly where it may be icy.

Questions people ask
Why not use high beams in fog?
Their light bounces back off the fog and dazzles you: you see less, not more. Use low beams, and fog lights if you have them. Source: US National Weather Service (NWS).
What should I do if I can see almost nothing?
Turn on your hazard lights and pull into a safe place, such as a car park. If you have to stop at the roadside, pull as far off as you can, keep only the hazard lights on and take your foot off the brake. Source: US National Weather Service (NWS).
