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 Watch

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

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.

Flash Flood Warning

Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.

Severe Thunderstorm Watch

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