MONTHLY TROPICAL WEATHER SUMMARY
NATIONAL WEATHER SERVICE MIAMI FL

SUMMARY OF TROPICAL CYCLONE ACTIVITY FOR AUGUST 2001...
FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...
TROPICAL CYCLONE ACTIVITY WAS A BIT BELOW NORMAL IN AUGUST.
AN AVERAGE AUGUST HAS THREE NAMED STORMS...OF WHICH TWO BECOME
HURRICANES. THERE WERE THREE TROPICAL STORMS DURING AUGUST...
BARRY...CHANTAL...AND DEAN...BUT NO HURRICANES. THIS IS THE FIRST
AUGUST TO HAVE NO HURRICANES SINCE 1997. THIS IS ALSO THE FIRST
SEASON SINCE 1988 TO HAVE NO HURRICANES OBSERVED PRIOR TO SEPTEMBER.
BARRY FORMED FROM A TROPICAL WAVE OVER THE EASTERN GULF OF MEXICO
ON 2 AUGUST. INITIALLY MOVING WEST-NORTHWEST...THE STORM SLOWED
TO AN ERRATIC DRIFT ON THE 3RD THAT CONTINUED INTO THE 4TH.
UNFAVORABLE UPPER LEVEL WINDS CAUSED BARRY TO WEAKEN TO A DEPRESSION
EARLY ON THE 4TH...WITH THE CYCLONE REGAINING TROPICAL STORM
STRENGTH LATER THAT DAY. BARRY MOVED NORTH AND INTENSIFIED ON THE
5TH...MAKING LANDFALL AT JUST UNDER HURRICANE STRENGTH IN THE
FLORIDA PANHANDLE BETWEEN PANAMA CITY AND DESTIN EARLY ON THE 6TH.
THE CYCLONE TURNED NORTHWEST AND WEAKENED TO A DEPRESSION OVER
SOUTHWESTERN ALABAMA...THEN WEAKENED FURTHER TO A LOW OVER NORTHERN
MISSISSIPPI. THE REMNANTS OF BARRY WERE LAST SEEN OVER SOUTHEASTERN
MISSOURI ON THE 8TH. WINDS AND RAINS ASSOCIATED WITH BARRY CAUSED
MINOR DAMAGE IN THE FLORIDA PANHANDLE.
CHANTAL ORIGINATED FROM A TROPICAL WAVE...FIRST BECOMING A
DEPRESSION ON 14 AUGUST ABOUT 1500 MILES EAST OF THE SOUTHERN
WINDWARD ISLANDS. THE DEPRESSION MOVED WESTWARD SO RAPIDLY THAT IT
WAS UNABLE TO MAINTAIN A CLOSED SURFACE CIRCULATION AND DEGENERATED
INTO AN OPEN WAVE ON THE 16TH. IT MOVED THROUGH THE LESSER ANTILLES
AS A WAVE BUT DID PRODUCE WINDS OF TROPICAL STORM FORCE AT
MARTINIQUE. THE WAVE SLOWED DOWN IN THE EASTERN CARIBBEAN...AND
WHEN A CIRCULATION REDEVELOPED ON THE 17TH THE SYSTEM BECAME A
TROPICAL STORM. CHANTAL MOVED WESTWARD THROUGH THE CARIBBEAN...
BRIEFLY REACHING AN INTENSITY OF 70 MPH ON THE 19TH WHEN IT WAS
SOUTH OF JAMAICA. CHANTAL WEAKENED LATE ON THE 19TH...BUT BEGAN TO
STRENGTHEN AGAIN AS IT APPROACHED BELIZE AND THE YUCATAN PENINSULA.
CHANTAL MADE LANDFALL NEAR THE BELIZE-MEXICO BORDER LATE ON THE 20TH
WITH WINDS OF 70 MPH. CHANTAL WEAKENED TO A DEPRESSION AND THEN
DISSIPATED OVER SOUTHEASTERN MEXICO ON THE 22ND. THERE WERE NO
CASUALTIES ASSOCIATED WITH CHANTAL WHILE IT WAS A TROPICAL
CYCLONE...ALTHOUGH TWO DEATHS WERE REPORTED IN TRINIDAD FROM
LIGHTNING ASSOCIATED WITH THE PASSAGE OF THE TROPICAL WAVE THROUGH
THE LESSER ANTILLES. DAMAGE IN BELIZE IS ESTIMATED AT $10-15
MILLION. THERE WERE NO REPORTS OF SIGNIFICANT DAMAGE IN MEXICO.
DEAN FORMED FROM A TROPICAL WAVE OVER THE VIRGIN ISLANDS ON 22
AUGUST...AND A HURRICANE HUNTER PLANE INDICATED THAT ITS WINDS WERE
NEAR HURRICANE FORCE LATER THAT DAY. HOWEVER...THE SYSTEM SOON
ENCOUNTERED AN UNFAVORABLE ENVIRONMENT AND IT WEAKENED TO A TROPICAL
WAVE JUST NORTH OF PUERTO RICO THE NEXT DAY. DEANS REMNANTS MOVED
MOSTLY NORTHWARD FOR THE NEXT SEVERAL DAYS...AND INTERACTED WITH A
LARGE NON-TROPICAL TROUGH OFF THE U.S. EAST COAST. ON THE
26TH...THUNDERSTORM ACTIVITY BEGAN TO ORGANIZE NEAR THE REMNANT LOW
PRESSURE INDICATING THAT IS WAS AGAIN ACQUIRING TROPICAL
CHARACTERISTICS. DEAN RE-ATTAINED TROPICAL STORM STATUS LATE ON THE
26TH WHILE LOCATED ABOUT 400 MILES NORTH-NORTHEAST OF BERMUDA.
AFTER STRENGTHENING TO JUST BELOW HURRICANE FORCE...DEAN CONTINUED
NORTHEASTWARD AND BECAME EXTRATROPICAL THE FOLLOWING DAY. WINDS TO
TROPICAL FORCE WERE REPORTED IN THE U.S. VIRGIN ISLANDS...AND THERE
WAS DAMAGE DUE TO FLOODING IN PUERTO RICO.
