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.

Dense Fog Advisory

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

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.

Winter Storm Warning

Heavy snow, sleet or ice that makes travel dangerous is occurring or imminent. Avoid travel if you can.

Red Flag Warning

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

Winter Storm Watch

A significant winter storm is possible. Prepare for hazardous travel and stock up ahead of time.

Fire Weather Watch

Questions

About Fergus County alerts

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

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

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