FAQ
Where do the warnings come from?
From the SIVS system of the Czech Hydrometeorological Institute (ČHMÚ) — the official source of weather warnings for Czechia.
What do the warning colours mean?
Yellow = be aware, orange = dangerous conditions, red = extremely dangerous. The level reflects the expected intensity.
How often are warnings updated?
Continuously, as ČHMÚ issues and cancels them. Active warnings appear at the top and on the live radar.
