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.

Flood Advisory

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

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.

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.

Hydrologic Outlook

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

About Judith Basin County alerts

Where do these alerts come from?

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.
