...DOWNBURSTS HIT WESTERN PENNSYLVANIA ON TUESDAY...
THUNDERSTORMS RIPPED THROUGH WESTERN PENNSYLVANIA PRODUCING SEVERAL
DOWNBURSTS ON TUESDAY. ARMSTRONG...INDIANA...AND LAWRENCE COUNTIES
ALL RECEIVED DAMAGE FROM MICROBURTS. IN INDIANA COUNTY...WINDS WERE
ESTIMATED NEAR 60 MPH.
IN LAWRENCE COUNTY...A MICROBURST WITH ESTIMATED WINDS ABOUT 70 MPH
SNAPPED OR TOPPLED HUNDREDS OF TREES. THIS MICROBURST WAS ABOUT THREE
QUARTERS OF A MILE WIDE AND EXTENDED FOR ABOUT 6 MILES FROM THE OHIO
BORDER NORTH OF HILLSVILLE WEST THROUGH MAHONING TOWNSHIP INTO UNION
TOWNSHIP (WEST OF NEW CASTLE). THE HARDEST HIT AREA WAS MAHONING
TOWNSHIP WITH A LARGE NUMBER OF TREES TOPPLED OR UPROOTED. SEVERAL
TREES FELL ON PARTS OF HOUSES. ONE ROOF WAS PARTIALLY DESTROYED.
SEVERAL SHEDS AND GARAGES ALSO SUFFERED DAMAGE. NUMEROUS POWER LINES
AND TELEPHONE LINES WERE ALSO DOWNED. ONE OF THE HARDEST HIT AREAS
WITHIN MAHONING TOWNSHIP WAS THE HILLTOP AREA JUST OFF ROUTE 224.
A DOWNBURST IS A STRONG WIND GUST ON OR NEAR THE GROUND WHICH IS
GENERATED BY A THUNDERSTORM. A MACROBURST IS A DOWNBURST THAT
PRODUCES A SWATH OF DAMAGE 2.5 MILES OR GREATER IN WIDTH. A
MICROBURST IS A DOWNBURST WHICH PRODUCES A SWATH OF DAMAGE LESS THAN
2.5 MILES WIDE. DOWNBURSTS OCCUR MUCH MORE FREQUENTLY THAN TORNADOES
AND THEY CAN PRODUCE MORE DAMAGE OVER A LARGER AREA THAN SMALL
TORNADOES.
