Take Tornado Watches Seriously

After a dynamic start to the tornado season, it has really quieted down some, with regard to severe storms.  This provides time to discuss some tornado preparedness issues.

Schools often overlook the tornado watch.  According to the National Oceanic and Atmospheric Administration (NOAA), a tornado watch is "issued by the National Weather Service when conditions are favorable for the development of tornadoes in and close to the watch area. They are usually issued for a duration of 4 to 8 hours. They normally are issued well in advance of the actual occurrence of severe weather. During the watch, people should review tornado safety rules and be prepared to move a place of safety if threatening weather approaches."  Schools will often overlook this because during a tornado watch, the sun may still be shining, and local conditions may still be pleasant.

This is the danger.  During a tornado watch, the weather may change quickly, and violently.  The types of storms that produce tornadoes often produce down-drafts that can send straight-line winds miles from the storm.  Thus, a beautiful day can change into one of carnage quickly.  This is what led to the Indiana State Fair (video) stage roof collapse tragedy last year. 

When a tornado watch is issued, curtail outdoor activities.  Give yourself access to weather radar and keep an eye on it.  Alert your staff, and have them be prepared to take shelter at a moment's notice.

Take tornado watches seriously.
