A watch means be ready
A severe thunderstorm watch means storms with large hail and damaging wind are possible. Watches are large, covering numerous counties or even states, for a period of two to eight hours. When severe weather is reported or seen on radar, the National Weather Service issues a severe thunderstorm warning for a much smaller area, about the size of a city or small county.
What to do during a severe thunderstorm watch
- Stay informed and be ready to act if a severe thunderstorm warning is issued.
- Know where you will take shelter in a sturdy building, away from windows. Mobile homes can blow over in high winds.
- See severe thunderstorm warnings in effect right now.
