Downbursts and straight-line winds associated with thunderstorms can \u00a0produce winds of 100-150 miles per hour. Of the estimated 100,000 thunderstorms in the United States each year, only about 10% are classified as severe.\u00a0Lightning, a major threat during thunderstorms, is responsible for more deaths \u00a0annually than tornadoes. Since lightning strikes are very unpredictable, the risk to individuals and property can be significant.<\/p>\n<p>A <strong>SEVERE THUNDERSTORM WARNING<\/strong> means that there are currently severe thunderstorms in the area or that one is imminent based on Doppler radar. These storms are potentially accompanies by cloud-to-ground lightning, high winds, and hail. Thunderstorms are classified as \u201cSevere\u201d if they produce hail that is dime size (.75\u201d in diameter or larger) and\/or wind gusts to 58 mph or more, or produce a tornado.<\/p>\n<p>During a thunderstorm\/lightning event, you should:<\/p>\n<ul>\n<li>Seek sturdy indoor shelter and stay away from windows and doors.<\/li>\n<li>Do not touch items that conduct electricity.<\/li>\n<li>Avoid contact with electrical equipment or cords. Unplug appliances and other electrical items such as computers and turn off air conditioners.<\/li>\n<li>DO NOT lie on concrete floors and do not lean against concrete walls.<\/li>\n<li>Avoid natural lightning rods such as a tall, isolated tree in an open area.<\/li>\n<li>Avoid contact with anything metal\u2014motorcycles, golf carts, golf clubs, and bicycles.<\/li>\n<li>If you are driving, try to safely exit the roadway and park.

To estimate your distance from the lightning flash, use the \u201cFlash to Bang\u201d method: if you observe lightning, count the number of seconds until you hear thunder. Divide the number of seconds by five in order to get the distance in miles.<\/p>\n<p>Lightning can strike up to 10 miles from a storm. Seek shelter as soon as you hear thunder or see lightning.\u00a0Go to a safe location if the time between the lightning flash and the thunder clap is 30 seconds or less.\u00a0The chance of being struck by lightning is approximately 1 in 600,000. However, this can be reduced even further by following safety precautions.\u00a0Lightning strikes are serious medical emergencies requiring immediate attention. Contrary to popular belief, lightning strike victims carry no electrical charge and should be attended to immediately.<\/p>\n<p><strong>HPU Lightning Response:<br \/>\n<\/strong>When lightning is detected within 8 miles of campus, all pools will be evacuated and card access restricted. Pool access will be restricted until the storm passes (30 minutes after a lightning strike within 8 miles).
