...ALABAMA AND TENNESSEE SEVERE WEATHER AWARENESS WEEK CONTINUES...
...TODAY WE DISCUSS SEVERE THUNDERSTORMS...

THERE ARE APPROXIMATELY 2000 THUNDERSTORMS IN PROGRESS AROUND THE
WORLD AT ANY GIVEN TIME. MANY OF THESE STORMS ARE BENEFICIAL AND
BRING NEEDED RAINFALL. ONLY A SMALL FRACTION /LESS THAN ONE PERCENT/
ARE CLASSIFIED AS SEVERE. SEVERE THUNDERSTORMS ARE THOSE
THUNDERSTORMS THAT PRODUCE HAIL ONE INCH IN DIAMETER AND LARGER...
AND/OR STRONG WIND GUSTS OF 58 MILES PER HOUR OR GREATER. HAIL THAT
IS ONE INCH IN DIAMETER IS ABOUT THE SIZE OF A QUARTER.

THE TENNESSEE VALLEY PEAK SEVERE WEATHER SEASON IS MARCH...APRIL AND
MAY...WITH THE MAJORITY OF SEVERE WEATHER ACTIVITY OCCURRING BETWEEN
THE MID AFTERNOON AND EARLY TO MID EVENING HOURS. HOWEVER...IT IS
IMPORTANT TO REMEMBER THAT SEVERE THUNDERSTORMS CAN OCCUR IN ANY
MONTH OF THE YEAR...AND AT ANYTIME OF THE DAY OR NIGHT...ACROSS THE
TENNESSEE VALLEY.

IN ADDITION...GIVEN THE RIGHT ATMOSPHERIC CONDITIONS...SEVERE
THUNDERSTORMS CAN RAPIDLY PRODUCE TORNADOES. ALL THUNDERSTORMS
PRODUCE LIGHTNING. THE HEAVY RAINS OR LIGHTNING ACTIVITY IN A
THUNDERSTORM DO NOT HAVE ANYTHING TO DO WITH A THUNDERSTORM BEING
CLASSIFIED AS `SEVERE`...BUT THESE IMPACTS CAN STILL POSE A THREAT
TO LIFE AND PROPERTY. IT IS CRITICAL TO BE PREPARED AND REACT PROPERLY
TO THUNDERSTORMS...PARTICULARLY SEVERE THUNDERSTORMS. MONITOR WEATHER
CONDITIONS CLOSELY WHEN SEVERE WEATHER IS EXPECTED TO IMPACT YOUR AREA.

---HERE ARE SOME SEVERE THUNDERSTORM SAFETY RULES---

1) FIND SHELTER IMMEDIATELY. GO TO A STURDY BUILDING THAT WILL
WITHSTAND HIGH WINDS. STAY AWAY FROM WINDOWS AND AVOID ELECTRICAL
APPLIANCES AND TELEPHONES.

2) A SEVERE THUNDERSTORM **WATCH** MEANS THAT CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS TO DEVELOP WITHIN THE NEXT FEW
HOURS. HOWEVER...SEVERE THUNDERSTORMS CAN OCCUR WITHOUT A WATCH IN
EFFECT. KEEP AN EYE TO THE SKY AND LISTEN TO YOUR LOCAL MEDIA OR NOAA
WEATHER RADIO FOR ANY SEVERE WEATHER WARNINGS AND STATEMENTS.

3) A SEVERE THUNDERSTORM **WARNING** MEANS THAT A SEVERE THUNDERSTORM
IS EITHER IMMINENT OR OCCURRING. THE SEVERE THUNDERSTORM HAS EITHER
BEEN DETECTED BY NATIONAL WEATHER SERVICE DOPPLER RADAR OR HAS BEEN
REPORTED TO THE NATIONAL WEATHER SERVICE BY SKYWARN SPOTTERS OR
LOCAL LAW ENFORCEMENT IN A PARTICULAR AREA/COUNTY.

4) WHEN A SEVERE THUNDERSTORM WARNING IS ISSUED FOR YOUR AREA...TAKE
ACTION IMMEDIATELY AND GO TO A SAFE SHELTER. SEVERE THUNDERSTORMS
CAN PRODUCE **DAMAGING WINDS** IN EXCESS OF 60 MPH...LARGE HAIL...AND
FREQUENT CLOUD TO GROUND LIGHTNING ALONG WITH TORRENTIAL RAINFALL.

5) SECURE LOOSE OUTDOOR OBJECTS /SUCH AS PATIO FURNITURE/ AHEAD
OF TIME. DO NOT TAKE THE TIME TO DO THIS IF A WARNING IS ALREADY
IN EFFECT FOR YOUR LOCATION! IT WOULD BE A GOOD IDEA TO BRING YOUR
VEHICLE INSIDE A GARAGE.
