Plain English
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.
Sustained winds of 30 mph or more, or gusts to 45 mph, are expected. Use caution driving high-profile vehicles.
Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.
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.
Sustained winds of 40 mph or more, or gusts of 58 mph or more, are expected. Secure loose objects and expect downed trees and power lines.
Damaging winds are possible. Secure loose objects ahead of time.
Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.
Extremely dangerous heat. Avoid strenuous activity, stay in cool spaces and never leave people or pets in a vehicle.
Conditions are favourable for flooding. Have a plan in case a warning is issued.
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.
