Storms in Europe — radar, alerts and what to do

A storm in the Alps behaves nothing like a storm over the Baltic, and the warning you would get in Croatia may never reach a foreign phone. Below is a tool for checking your own location and an overview of what is worth knowing before you travel.

Storms in Europe — radar, alerts and what to do

Check the storm for your town

Enter a town name and you get a storm forecast for the next 12 hours: when it starts, how long it lasts and which direction it arrives from.

Data comes from the ICON-D2 model (2 km resolution, 15-minute steps). This is a model forecast, not a radar reading — check again before heading out.

Warning systems, country by country

  • Poland. IMGW issues three-level warnings; RCB sends SMS alerts when life is at risk. The RCB alert reaches every phone within range of a mast — nothing to install.
  • Croatia. DHMZ issues warnings, but a tourist on a foreign SIM usually will not receive them. The bura wind can close the Adriatic highway within an hour.
  • France. Météo-France uses a four-colour vigilance scale. The Cévennes episode is a phenomenon found nowhere else in Europe at this scale — a month of rain in a few hours.
  • Germany and Austria. DWD and GeoSphere warn regionally; in the Alps the difference between valley and pass is often the difference between rain and hail.

Emergency number across the EU: 112.

What to do once the storm is here

The 30/30 rule: if fewer than 30 seconds pass between flash and thunder, the storm is closer than 10 km — get under a roof. Come back out no sooner than 30 minutes after the last thunder.

A car is safe, but not because of its rubber tyres — it works as a Faraday cage, provided the roof is metal. A convertible offers no protection.

In the mountains, come down off ridges and passes, do not shelter under a lone tree, and stay away from metal railings and fixed cables.

Wind and weather — Europe

Wind direction and speed decide which way a fire runs. Switch the layer to temperature or humidity to judge the risk.

Strong wind, temperatures above 35 °C and humidity below 30% together are the conditions in which fire spreads fastest.

Questions and answers

Frequently asked questions

How far away is the storm when I hear thunder?
Count the seconds between flash and thunder and divide by three — the result is the distance in kilometres. Ten seconds means roughly three kilometres.
Will I get a warning abroad?
It depends on the country and operator. Systems such as ES-Alert or IT-Alert reach phones in range, but not always in a language you read. Do not rely on them alone.
Are mountain storms more dangerous?
Yes. They build faster because the terrain forces air upward, and getting away takes longer. In the Alps a storm can form in under an hour.
How reliable is a storm forecast?
Not fully. Storms are small-scale events and the model gives probability, not certainty. That is why it is worth checking again right before you leave.
Does this site issue official warnings?
No. We show a model forecast. Binding information comes from national services — IMGW, DHMZ, Météo-France, DWD.
