Plain English

What these alerts mean

A warning means the hazard is happening or about to; a watch means conditions favour it; an advisory is a lesser hazard still worth planning around.

Flash Flood Warning

Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.

Flood Watch

Conditions are favourable for flooding. Have a plan in case a warning is issued.

Special Weather Statement

A heads-up about conditions that do not meet warning or advisory criteria but still deserve attention, such as a strong storm, patchy fog or a brief burst of snow.

Winter Weather Advisory

Snow, sleet or freezing rain that makes travel slippery is expected. Allow extra time and drive carefully.

Flood Advisory

Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.

Red Flag Warning

Critical fire weather: dry fuels, low humidity and gusty winds. Any fire can spread rapidly; avoid outdoor burning.

Lake Wind Advisory

Winds strong enough to make lake waters hazardous for small boats.

Heat Advisory

Heat index values high enough to cause heat illness with prolonged exposure. Drink water, stay in air conditioning and check on neighbours.

Wind Advisory

Questions

About Fresno County alerts

How do I get Fresno County weather alerts on my iPhone?

Install Forecast Bar, add Fresno County as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Fresno County then arrives as a push notification at the moment of issue, with Critical Alerts available for the most dangerous warnings. Forecast Bar also runs on iPad, Apple Watch, Mac and Apple TV.

Where do these alerts come from?

From the National Weather Service alert feed (api.weather.gov). NWS issues alerts by county and by forecast zone; this page lists every product that names Fresno County. Forecast Bar checks the feed continuously and this page refreshes within a few minutes of a change.

What is the difference between a watch, a warning and an advisory?

A warning means the hazard is occurring, imminent or very likely: act now. A watch means conditions are favourable for it to develop: prepare and stay informed. An advisory covers a hazard that is less serious than a warning but can still cause real inconvenience or danger if you are not ready for it.

Can I get this data as JSON?

Yes. /weather-alerts/ca/fresno-county.json returns the active alerts, the last 30 days and the 12-month counts for Fresno County, refreshed every minute. Please cache responses and credit National Weather Service as the source.
