Watches vs warnings
Knowing the difference between severe watches and warnings is crucial to helping you and your family stay safe before and during severe weather.
A watch means ingredients are in place for severe weather to develop. This means severe weather could happen, and you should have a plan ready in case severe weather develops later in the day.
A warning means severe weather is happening, and you need to take action now to protect yourself, others and your property.
In addition to watches and warnings, there are outlooks that can be issued days in advance. Different threat levels are given to different areas.
Ready, get set, go
READY | If your town is in a severe outlook, be ready. Pay attention to the forecast in the coming hours and days, as severe weather may be possible.
GET SET | If a severe weather watch is issued for your town, that means ingredients are present for severe weather to occur. Severe weather is going to be possible.
GO | A severe warning has been issued. That means severe weather is happening now. Take cover.
