PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NEW YORK NY
600 AM EDT TUE APR 28 2015

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

THE NATIONAL WEATHER SERVICE IN PARTNERSHIP WITH SEVERAL AGENCIES
INCLUDING THE NY STATE DISASTER PREPAREDNESS COMMISSION IS PROMOTING
SEVERE WEATHER SAFETY FOR ALL PEOPLE.

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. A TYPICAL EXAMPLE WOULD BE RAPIDLY DEVELOPING SEVERE
THUNDERSTORMS FORMING IN A MOIST UNSTABLE AIR MASS AHEAD OF A QUICK
MOVING STRONG COLD FRONT. TYPICAL DAMAGE WOULD RESULT FROM STRONG
WIND GUSTS ALONG THE LEADING EDGE OF A LINE OF THUNDERSTORMS. WINDS
THAT BLOW FROM ONE DIRECTION ARE CALLED STRAIGHT LINE WINDS.

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 BEFORE A POTENTIAL EVENT 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...INCLUDING THE LOWER HUDSON VALLEY...NEW YORK CITY AND LONG
ISLAND...5 COUNTIES IN NORTHEAST NEW JERSEY AND 4 COUNTIES IN
SOUTHERN CONNECTICUT. WE USE A COMBINATION OF DOPPLER RADAR AND
VOLUNTEER SKYWARN SPOTTER OBSERVATIONS TO ISSUE WARNINGS. LAST
YEAR...WE CORRECTLY DETECTED AND WARNED FOR 93 PERCENT OF 135 SEVERE
THUNDERSTORM EVENTS WITH AN AVERAGE LEAD TIME OF 21 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.

WHEN YOU NEED TIMELY WEATHER INFORMATION...TUNE TO NOAA WEATHER
RADIO ALL HAZARDS...THE OFFICIAL VOICE OF THE NWS.

THE NEXT STATEMENT COVERS SEVERE WEATHER PREPAREDNESS AND SAFETY.
