...REVIEW OF JULY 31 STORM IN BUCKEYE...

THE NATIONAL WEATHER SERVICE IN PHOENIX CONDUCTED AN ANALYSIS OF THE
STORM THAT AFFECTED BUCKEYE ON THE EVENING OF JULY 31. THE ANALYSIS
INCLUDED A REVIEW OF RADAR DATA...STORM SPOTTER PHOTOGRAPHS...AND
DAMAGE IMAGES.

BASED ON THE ANALYSIS...IT WAS DETERMINED THAT A MICROBURST IMPACTED
THE BUCKEYE AREA. MAXIMUM WINDS IN THE MICROBURST ARE ESTIMATED TO
HAVE BEEN IN THE 70 MPH RANGE...OR NEAR HURRICANE FORCE.

A MICROBURST IS A DAMAGING WIND EVENT RESULTING FROM A STRONG
DOWNDRAFT...OR DOWNWARD-MOVING AIR CURRENT...IN A THUNDERSTORM. AS
THE DOWNDRAFT HITS THE GROUND...IT SPREADS OUT ALONG THE GROUND AND
THE DAMAGING WINDS ARE PRODUCED.
