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.

Dense Fog Advisory

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

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

Critical fire weather conditions are possible. Postpone outdoor burning.

Flash Flood Watch

Conditions may lead to flash flooding. Be ready to move to higher ground.

Flood Watch

Conditions are favourable for flooding. Have a plan in case a warning is issued.

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.

Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.

Questions

About Broadwater County alerts

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

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