THIS STATEMENT COVERS SEVERE THUNDERSTORMS. HIGH WINDS PRODUCED BY SEVERE THUNDERSTORMS CAUSE DEATHS AND INJURIES ACROSS THE TRI-STATE REGION ANNUALLY. ALTHOUGH HAIL CAN DAMAGE PROPERTY AND INJURE PEOPLE AND ANIMALS...IT RARELY KILLS. CLIMATOLOGICALLY...SEVERE THUNDERSTORMS OCCUR MOST FREQUENTLY DURING THE LATE AFTERNOON TO EARLY EVENING...BETWEEN MAY AND EARLY SEPTEMBER. AN EXAMPLE WOULD BE RAPIDLY DEVELOPING SEVERE THUNDERSTORMS FORMING AHEAD OF A QUICK MOVING COLD FRONT. DAMAGE WOULD RESULT FROM STRONG WIND GUSTS ALONG THE LEADING EDGE OF A LINE OF SEVERE THUNDERSTORMS. WINDS THAT BLOW FROM ONE DIRECTION ARE CALLED STRAIGHT LINE WINDS. THE STRONGEST SEVERE THUNDERSTORMS CAN PRODUCE DAMAGING WIND GUSTS FROM 80 TO OVER 100 MPH. A COMPLEX OF THUNDERSTORMS PRODUCING SUCH STRONG WINDS OVER A LARGE AREA FOR SEVERAL HOURS IS CALLED A DERECHO. SEVERE WEATHER OUTLOOKS ARE ISSUED BY THE NWS STORM PREDICTION CENTER UP TO 8 DAYS BEFORE A POTENTIAL EVENT AND BY NWS NEW YORK NY UP TO 7 DAYS BEFOREHAND IN OUR HAZARDOUS WEATHER OUTLOOK. SEVERE THUNDERSTORM WATCHES ARE ISSUED BY THE NWS STORM PREDICTION CENTER WITH LEAD TIMES UP TO 6 HOURS. A WATCH MEANS THAT WEATHER CONDITIONS ARE FAVORABLE FOR THE DEVELOPMENT OF SEVERE THUNDERSTORMS IN AND AROUND AN AREA...USUALLY COVERING AN AREA OF SEVERAL THOUSAND SQUARE MILES...AT LEAST THE SIZE OF NEW JERSEY. SEVERE THUNDERSTORM WARNINGS ARE ISSUED BY YOUR NATIONAL WEATHER SERVICE OFFICE ON LONG ISLAND FOR 11 COUNTIES IN SOUTHEAST NEW YORK...USING A COMBINATION OF DOPPLER RADAR AND VOLUNTEER SKYWARN SPOTTER OBSERVATIONS. LAST YEAR...WE CORRECTLY DETECTED AND WARNED FOR 84 PERCENT OF 101 SEVERE THUNDERSTORM EVENTS WITH AN AVERAGE LEAD TIME OF 15 MINUTES. WHEN A WARNING IS ISSUED...TAKE PROTECTIVE ACTION TO SAVE YOUR LIFE OR MINIMIZE DAMAGE TO YOUR PROPERTY. IF THERE IS TIME...SECURE OUTDOOR OBJECTS THAT COULD BLOW AWAY OR CAUSE DAMAGE. REMEMBER THE LIGHTNING SAFETY RULE...IF THUNDER ROARS GO INDOORS. ONCE INDOORS STAY THERE INDOORS FOR 30 MINUTES AFTER LAST SEEING LIGHTNING OR HEARING THE LAST CLAP OF THUNDER. GET INSIDE A HOME...BUILDING...OR HARD TOP AUTOMOBILE - NOT A CONVERTIBLE. ALTHOUGH YOU MAY BE INJURED IF LIGHTNING STRIKES YOUR CAR...YOU ARE MUCH SAFER INSIDE A HARD TOP VEHICLE THAN OUTSIDE. THE NEXT STATEMENT COVERS SEVERE WEATHER PREPAREDNESS AND SAFETY. $$
