Never underestimate the power

West Michigan regularily sees violent thunderstorms producing strong winds, large hail, lightning and tornados.

Do you remember May 31, 1998, when straight line winds caused damage from the lakeshore through Kent County? A series of thunderstorms created a rare weather event -- a derecho. These winds were powerful enough to knock down buildings, uproot trees, and overturn recreational vehicles.

Early detection of these thunderstorms gave people enough time to seek shelter. It serves as a dangerous reminder that severe thunderstorms should be treated with respect.

First know the difference between a thunderstorm warning and a thunderstorm watch.

• A severe thunderstorm watch means conditions exist for severe weather to develop.   This is the time to review your safety procedures.
• A severe thunderstorm warning issued by the National Weather Service means a storm has been spotted, or doppler radar indicates a thunderstorm capable of producing damaging winds, large hail, lightning and heavy rain.

Even the gentlest of thunderstorms can change quickly into something larger and more deadly. So be prepared to take action.

• Move inside immediately and seek the lowest level, preferably a small, inside room, away from any windows.
• Telephone lines and metal pipes can conduct electricity. Use the phone only in an emergency.
• If you're too far from shelter find a low spot away from trees, fences and poles.
• Crouch down, on your toes, like a baseball catcher, and tuck your head between your knees. 

Like a home fire drill, a severe weather drill is an important part of your family's safety. Make sure you're prepared for the worst.
