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.

High Surf Advisory

Large breaking waves are expected on beaches, with dangerous rip currents. Stay off jetties and out of the water.

Flood Advisory

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

Questions

About Arcadia alerts

How do I get Arcadia weather alerts on my iPhone?

Install Forecast Bar, add Arcadia as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Los Angeles 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 Los Angeles County, the county Arcadia sits in. 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/arcadia.json returns the active alerts, the last 30 days and the 12-month counts for Arcadia, refreshed every minute. Please cache responses and credit National Weather Service as the source.
