Right now
The most recent data we hold from METEOALARM arrived 12 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 7 October 2026 at 04:59 UTC. It is kept here as a record.
No stronger detection stands among the 10 recorded within 20 km of this point since 1 September 2026 — 9 others scored the same. The last comparable one was on 3 October 2026. 5 more were recorded here in the fortnight before it.

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 · Vilnius
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).
