What the map shows

The estimate comes from INCA, ARSO’s very-short-range forecasting system, which combines radar measurements with other data. Coloured areas show where hail was likely at the time of the frame.

How to use it

The map shows conditions at the time of the frame, not a forecast for the coming hours. If a storm is approaching, play the last hour to judge its direction.

In dangerous weather, follow ARSO’s official warnings.

Frequently asked questions

Does the map predict where hail will fall?

No. It shows an estimate for the time of each frame. The animation only helps you judge where a storm is heading.

Why is the map mostly empty?

Hail is rare. Coloured areas appear mainly during summer thunderstorms.
