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.

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

Critical fire weather conditions are possible. Postpone outdoor burning.

Questions

About San Luis Obispo County alerts

How do I get San Luis Obispo County weather alerts on my iPhone?

Install Forecast Bar, add San Luis Obispo County as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for San Luis Obispo 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 San Luis Obispo 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.
