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.

Winter Weather Advisory

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

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.

Dense Fog Advisory

Visibility of a quarter mile or less is expected. Slow down and use low beams.

High Wind Warning

Sustained winds of 40 mph or more, or gusts of 58 mph or more, are expected. Secure loose objects and expect downed trees and power lines.

Severe Thunderstorm Warning

A storm with hail of 1 inch or larger, winds of 58 mph or more, or both, is occurring or imminent. Move indoors and away from windows.

Severe Thunderstorm Watch

Conditions are favourable for severe thunderstorms with large hail or damaging wind. Keep an eye on the sky and on warnings.

Hydrologic Outlook

Flooding may develop over the coming days as rain, snowmelt or river levels rise.

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.

Can I get this data as JSON?

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