Public Information Statement
Statement as of 7:06 PM CDT on July 9, 2009
... Severe Thunderstorm Watch safety rules...
A Severe Thunderstorm Watch means that conditions are favorable for the development of severe weather in the designated area. During a watch there is no cause for immediate concern. You should go about your normal business... but be on the lookout and keep up to date on the latest weather developments. Public safety officials should activate prearranged plans.
A Severe Thunderstorm Warning... on the other hand... means that a severe thunderstorm has been sighted or indicated by radar. People in the path of the storm should take immediate action to safeguard themselves and their family.
Technically speaking... a severe thunderstorm is defined as having wind gusts which exceed 58 mph and/or hail at least 3/4 inch in diameter. However... as these storms develop... they can be accompanied by tornadoes. Listen to NOAA Weather Radio or other local media to learn if a warning has been issued for your area. Also... keep a close watch on the thunderstorms as tornadoes can form quickly. If you see a tornado... move quickly into a basement. If none is available... seek shelter in a small interior room on the lowest floor and stay away from outside walls... doors and windows. In schools... factories or other institutional type buildings... stay out of auditoriums and gymnasiums.
