PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NEW YORK NY
602 AM EDT TUE APR 26 2015

...THIS IS SEVERE WEATHER AWARENESS WEEK...

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.
