Questions

About Blaine County alerts

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

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