Compared to hurricanes or winter storms, a thunderstorm is relatively small. The typical
thunderstorm is about 15 miles in diameter and generally lasts about 30 minutes. However,
despite their small size, all thunderstorms are potentially dangerous. When a thunderstorm
reaches "severe" limits, it has intensified to the point that it will produce wind gusts
of at least 58 mph and/or hail 3/4 inch in diameter (about the size of a dime) or larger.
When a SEVERE THUNDERSTORM WARNING is issued, large hail may pelt you, your home, your pets, and your property. These warnings are issued when a severe thunderstorm is indicated by radar, or reported by a reliable source. You should move to a safe place immediately. If time permits, consider moving vehicles into sheltered areas (garages, carports, etc.) and provide shelter for pets.
IF SEVERE WEATHER OCCURS IN YOUR AREA: remain in safe shelter until the
storms have passed. Once it is safe to leave the shelter, report any severe weather, such as a tornado,
or hail the size of dimes or larger, or wind damage such as snapped power lines, fallen trees or roof
damage to your local National Weather Service or contact your local law enforcement agency and
ask them to relay the information to the National Weather Service.
