Severe thunderstorms produce a variety of weather hazards including tornadoes, large hail, damaging straight line winds, flooding, and lightning. Now is the time to review Severe Weather Safety Information

Severe thunderstorms producing damaging winds in excess of 60 mph and large hail can be a threat to life and property. Damaging straight line winds are much more common than tornadoes and can be just as deadly.

Those caught outdoors during a severe thunderstorm are particularly vulnerable. Boaters and campers that enjoy the recreational opportunities of the Ozarks should be especially alert to the potential of severe storms. High winds associated with severe thunderstorms can strike suddenly. Winds in excess of 70 mph can easily capsize boats and put campers at risk due to falling trees.

Severe thunderstorms are defined by the National Weather Service as downdraft winds in excess of 58 miles an hour and/or hail 3/4 inch in diameter or greater. Since 1986, severe thunderstorm winds have killed 310 people and injured over 4000 nationwide.

Severe thunderstorms are reported each year in nearly all New Mexico counties.  Severe thunderstorms peak in the east during April through June and statewide July through August.

Severe thunderstorm safety rules...

The Storm Prediction Center in Norman, Oklahoma issues a SEVERE THUNDERSTORM WATCH to give you advance notice that severe thunderstorms are possible in your area. This gives you time to make preliminary plans for moving to a safe location if a severe thunderstorm warning is issued. The SPC also issues convective outlooks for days 1 through 3.

The SEVERE THUNDERSTORM WARNING is an urgent announcement that a severe thunderstorm has been reported or is imminent and warns you to take cover.  Severe thunderstorm warnings are issued by local NWS offices.

The strong wind gusts of severe thunderstorms can damage buildings, knock down trees, and create a hazard due to wind-blown debris:

    * Seek shelter but avoid trees as these are targets for lightning.
    * If indoors, stay away from windows and go to the safest location on the lowest level of your home.
    * When boating, always stay tuned to the latest weather reports and return to safe harbor before the strong winds arrive.
    * Mobile homes are especially vulnerable to the high winds of a thunderstorm and are subject to overturning and rolling if not properly anchored to the ground. Professional advice should be obtained from a reputable mobile home contractor. As a minimum, though, the frame should be secured with heavy steel straps. Heavy straps should also go over the top of the home with both frame and over the top ties secured in concrete footings.

What you can do before a storm strikes...

1) Know the county you live in and the names of the major nearby cities or towns. Severe weather warnings and statements are issued by county and reference major cities.

2) Check the latest weather forecast and hazardous weather outlook.

3) Watch for signs of an approaching thunderstorm.

4) If a storm is approaching, keep a NWR and/or AM/FM radio with you.

5) Postpone outdoor activities if thunderstorms are imminent. This is your best way to avoid being caught in a dangerous situation.

When thunderstorms approach...

1) REMEMBER that if you can hear thunder, you are close enough to a storm to be struck by lightning. Go to safe shelter immediately!

2) Move to a sturdy building or car. Do not take shelter in small sheds, under isolated trees, or in convertible automobiles.

3) If no shelter is nearby or available, get in the a hard top car and keep the windows up.

4) If you are boating or swimming, get out of boats and away from the water, get to land and find shelter immediately.

5) If you are indoors, unplug unnecessary appliances and only use the phone for emergencies.

6) If you are caught outside and no shelter is available:

    * Find a low spot away from trees, fences, and poles
    * Squat low to the ground on the balls of your feet, place your hands on your knees with your head between them, make yourself the smallest target possible and minimize your contact with the ground.


 Sixty-four tornadoes occurred in Southeast Kansas and Southwest Missouri in 2008 resulting in 19 fatalities and over 230 injuries in Missouri. Flash flooding during 2008 resulted in 9 fatalities. Lightning strikes from thunderstorms caused 17 injuries in Missouri last year.
