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.
Winds strong enough to make lake waters hazardous for small boats.
Snow, sleet or freezing rain that makes travel slippery is expected. Allow extra time and drive carefully.
Sustained winds of 30 mph or more, or gusts to 45 mph, are expected. Use caution driving high-profile vehicles.
Conditions are favourable for flooding. Have a plan in case a warning is issued.
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.
Flooding may develop over the coming days as rain, snowmelt or river levels rise.

Questions
About Flathead County alerts
How do I get Flathead County weather alerts on my iPhone?
Install Forecast Bar, add Flathead County as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Flathead 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 Flathead 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.
