Severe Thunderstorm Warning

National Weather Service

Never silenced by a preference toggle.

Severe weather

Beyond the hazards we compute ourselves, important official NWS alerts for your field's location are delivered straight through. This includes tornado, severe thunderstorm, flood, and more. Full alert details are always one step away.

Once a field is being monitored, these alerts always come through. Heat and UV alerts can each be turned off, and forecast storm alerts follow your lightning setting, but government warnings are not something to opt out of.
