MONTHLY TROPICAL WEATHER SUMMARY
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 AM EDT TUE NOV 1 2005

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

SIX TROPICAL CYCLONES...INCLUDING FOUR HURRICANES AND TWO TROPICAL
STORMS...FORMED DURING THE MONTH OF OCTOBER.  IN ADDITION...A
SUBTROPICAL DEPRESSION FORMED DURING THE MONTH...AND A SEPTEMBER
DEPRESSION CARRIED OVER INTO OCTOBER.  THE SIX NAMED STORMS THAT
FORMED IN OCTOBER TIES A RECORD LAST SET IN 1950.  THUS FAR IN
2005...THERE HAVE BEEN 23 NAMED STORMS...WITH 13 BECOMING
HURRICANES AND 7 BECOMING MAJOR HURRICANES.  WITH ONE MONTH STILL
REMAINING...THE 2005 HURRICANE SEASON HAS ALREADY ESTABLISHED NEW
RECORDS FOR THE MOST NAMED STORMS AND HURRICANES IN A SINGLE YEAR. 
BASED ON THE AVERAGE FOR THE LAST 40 YEARS...IN A NORMAL SEASON
THERE WOULD HAVE BEEN 10 TO 11 NAMED STORMS AND 6 HURRICANE
FORMATIONS.  

TROPICAL DEPRESSION NINETEEN FORMED IN LATE SEPTEMBER...
DISSIPATING ON 2 OCTOBER ABOUT 780 MILES WEST OF THE CAPE VERDE
ISLANDS. 

STAN DEVELOPED FROM A TROPICAL WAVE THAT GENERATED A PERSISTENT AREA
OF DISTURBED WEATHER OVER THE WESTERN CARIBBEAN SEA IN LATE
SEPTEMBER.  A TROPICAL DEPRESSION EVENTUALLY FORMED ON 1 OCTOBER
ABOUT 110 MILES SOUTHEAST OF COZUMEL MEXICO.  THE CYCLONE MOVED
WEST-NORTHWESTWARD...ATTAINING TROPICAL STORM STATUS JUST BEFORE
CROSSING THE EAST COAST OF THE YUCATAN PENINSULA ABOUT 40 MILES
SOUTH OF TULUM MEXICO ON 2 OCTOBER.  STAN TRAVERSED YUCATAN AND
WEAKENED TO A DEPRESSION...BUT IT SOON REGAINED TROPICAL STORM
STRENGTH AFTER IT MOVED INTO THE BAY OF CAMPECHE ON 3 OCTOBER.  THE
STORM TURNED FROM A WESTWARD TO A SOUTHWESTWARD HEADING...AND
CONTINUED TO STRENGTHEN.  STAN BECAME A HURRICANE AS IT NEARED THE
COAST OF MEXICO ON 4 OCTOBER AND IT MADE LANDFALL THAT DAY ABOUT 90
MILES EAST-SOUTHEAST OF VERACRUZ WITH MAXIMUM WINDS ESTIMATED AT 80
MPH.  THE CYCLONE WEAKENED RAPIDLY AFTER MOVING INLAND AND
DISSIPATED OVER THE MOUNTAINS OF SOUTHERN MEXICO ON 5 OCTOBER.

AROUND THE TIME OF STAN'S EXISTENCE...TORRENTIAL RAINS CAUSED SEVERE
FLASH FLOODS AND MUD SLIDES OVER PORTIONS OF MEXICO AND CENTRAL
AMERICA.  THERE WERE 652 DEATHS REPORTED IN GUATEMALA AND 133 WERE
REPORTEDLY KILLED IN MEXICO...EL SALVADOR...NICARAGUA...HONDURAS...
AND COSTA RICA.  IT IS IMPOSSIBLE...HOWEVER...TO DETERMINE HOW MANY
OF THESE DEATHS ARE DIRECTLY ATTRIBUTABLE TO STAN.

TAMMY WAS A SHORT-LIVED TROPICAL STORM THAT DEVELOPED JUST EAST OF
THE CENTRAL FLORIDA COAST AS A RESULT OF COMPLEX INTERACTION
BETWEEN AN UPPER-LEVEL LOW AND A TROPICAL WAVE. EARLY ON 5
OCTOBER...TAMMY QUICKLY DEVELOPED INTO A TROPICAL STORM ABOUT 20
MILES EAST OF CAPE CANAVERAL FLORIDA. THE CYCLONE MOVED STEADILY
NORTH-NORTHWESTWARD PARALLEL TO THE FLORIDA EAST COAST MOST OF
THAT DAY UNTIL IT TURNED NORTHWESTWARD AND MADE LANDFALL ALONG THE
NORTHEASTERN FLORIDA COAST NEAR MAYPORT VERY LATE THAT DAY WITH
MAXIMUM SUSTAINED WINDS OF 50 MPH.  TAMMY MOVED WESTWARD OVER
SOUTHERN GEORGIA AND SOUTHEASTERN ALABAMA ON 6 OCTOBER BEFORE
BECOMING ABSORBED BY A LARGER EXTRATROPICAL LOW PRESSURE SYSTEM
OVER THE FLORIDA PANHANDLE. NO SIGNIFICANT DAMAGE OCCURRED TO
STRUCTURES... BUT LOCALLY HEAVY RAINFALL OF 3-5 INCHES DID PRODUCE
SOME MINOR FLOODING ACROSS NORTHEASTERN FLORIDA AND SOUTHERN
GEORGIA.

SHORT-LIVED SUBTROPICAL DEPRESSION TWENTY-TWO FORMED ON 8 OCTOBER
ABOUT 450 MILES SOUTHEAST OF BERMUDA FROM A NON-TROPICAL LOW
PRESSURE SYSTEM.  THE CYCLONE MOVED NORTHWESTWARD TO
WEST-NORTHWESTWARD AND SOON DEGENERATED INTO A LOW PRESSURE AREA
ABOUT 250 MILES SOUTH-SOUTHEAST OF BERMUDA EARLY ON 9 OCTOBER.

VINCE...THE FIRST KNOWN TROPICAL CYCLONE TO MAKE LANDFALL IN
SPAIN...DEVELOPED FROM A NON-TROPICAL AREA OF LOW PRESSURE IN THE
EASTERN ATLANTIC...GRADUALLY ACQUIRING TROPICAL CHARACTERISTICS AND
BECOMING A TROPICAL STORM ON 9 OCTOBER ABOUT 515 MILES
EAST-SOUTHEAST OF THE AZORES.  IT STRENGTHENED AND BECAME A
HURRICANE LATER THAT DAY AS IT MOVED SLOWLY NORTHEASTWARD TO THE
NORTHWEST OF THE MADEIRA ISLANDS.  IT WEAKENED TO A TROPICAL STORM
THE NEXT DAY AS IT ACCELERATED TO THE EAST-NORTHEAST.  ON 11
OCTOBER...VINCE WEAKENED TO A TROPICAL DEPRESSION SHORTLY BEFORE
MAKING LANDFALL NEAR HUELVA SPAIN.  VINCE LOST TROPICAL
CHARACTERISTICS SHORTLY AFTER MAKING LANDFALL.

WILMA FORMED FROM A LARGE AREA OF DISTURBED WEATHER THAT STRETCHED
ACROSS MUCH OF THE CARIBBEAN SEA DURING THE SECOND WEEK OF OCTOBER. 
A SURFACE LOW PRESSURE SYSTEM GRADUALLY BECAME DEFINED NEAR JAMAICA
AND A TROPICAL DEPRESSION DEVELOPED ABOUT 215 MILES SOUTHEAST OF
GRAND CAYMAN ON 15 OCTOBER.  THE TROPICAL CYCLONE MOVED ERRATICALLY
SOUTHWARD FOR TWO DAYS WHILE SLOWLY STRENGTHENING INTO A TROPICAL
STORM.  WILMA BECAME A HURRICANE AND BEGAN A WEST-NORTHWESTWARD
MOTION ON 18 OCTOBER.  LATER THAT DAY...WILMA BEGAN TO STRENGTHEN
VERY RAPIDLY.   ON 19 OCTOBER IT BECAME A CATEGORY 5 HURRICANE...
AND ITS MINIMUM CENTRAL PRESSURE DROPPED TO AN ESTIMATED 882 MB...
WHILE ITS VERY SMALL EYE WAS CENTERED ABOUT 365 MILES SOUTHEAST OF
COZUMEL.   THIS IS THE LOWEST PRESSURE ON RECORD FOR A HURRICANE IN
THE ATLANTIC BASIN.  WILMA'S MAXIMUM INTENSITY IS ESTIMATED TO HAVE
BEEN 175 MPH.  ON 20 OCTOBER WILMA WEAKENED SLIGHTLY AND TURNED
NORTHWESTWARD TOWARD THE NORTHEASTERN YUCATAN PENINSULA.  ON 21
OCTOBER...THE HURRICANE MADE LANDFALL OVER COZUMEL...AND EARLY
THE NEXT DAY IT MADE LANDFALL OVER THE NORTHEASTERN YUCATAN
PENINSULA...BOTH AT CATEGORY 4 INTENSITY.  WILMA MOVED SLOWLY AND
WEAKENED OVER NORTHEASTERN YUCATAN AND EMERGED OVER THE GULF OF
MEXICO EARLY ON 23 OCTOBER AS A CATEGORY 2 HURRICANE.  LATER THAT
DAY IT TURNED NORTHEASTWARD AND ACCELERATED TOWARD THE SOUTHERN
FLORIDA PENINSULA.  THE HURRICANE STRENGTHENED AS IT APPROACHED THE
SOUTHWEST FLORIDA COAST...AND IT MADE LANDFALL NEAR CAPE ROMANO ON
24 OCTOBER WITH CATEGORY 3 INTENSITY.  THE SYSTEM CONTINUED TO
ACCELERATE NORTHEASTWARD...CROSSING FLORIDA IN LESS THAN 5 HOURS. 
WILMA MOVED INTO THE ATLANTIC JUST TO THE NORTH OF PALM BEACH AS A
CATEGORY 2 HURRICANE.  IT REGAINED CATEGORY 3 STATUS JUST OFF THE
CENTRAL EAST COAST OF FLORIDA...AND GRADUALLY WEAKENED THEREAFTER. 
THE HURRICANE MOVED RAPIDLY NORTHEASTWARD OVER THE WESTERN ATLANTIC
AND LOST TROPICAL CHARACTERISTICS ABOUT 205 MILES SOUTH-SOUTHEAST
OF HALIFAX NOVA SCOTIA ON 25 OCTOBER.

AT THIS TIME...25 DEATHS HAVE BEEN DIRECTLY ATTRIBUTED TO WILMA...12
IN HAITI...1 IN JAMAICA...6 IN MEXICO...AND 6 IN FLORIDA.  WILMA
CAUSED EXTENSIVE DAMAGE IN NORTHEASTERN YUCATAN...INCLUDING CANCUN
AND COZUMEL...AND SOUTHERN FLORIDA.  THE HURRICANE ALSO PRODUCED
MAJOR FLOODING OVER WESTERN CUBA.  DAMAGE FIGURES ARE INCOMPLETE.  

TROPICAL STORM ALPHA FORMED FROM A VIGOROUS TROPICAL WAVE WHICH
CROSSED THE WINDWARD ISLANDS ON 21 OCTOBER.  SHOWER ACTIVITY
BECAME CONCENTRATED SOUTH OF PUERTO RICO...AND RADAR DATA FROM THE
ISLAND HELPED DETERMINE THAT A TROPICAL DEPRESSION FORMED EARLY ON
22 OCTOBER.  THE DEPRESSION BECAME TROPICAL STORM ALPHA LATER THAT
DAY.  ALPHA MOVED NORTHWESTWARD AND DATA FROM HISPANIOLA INDICATE
THAT THE CYCLONE MADE LANDFALL NEAR BARARHONA IN THE DOMINICAN
REPUBLIC WITH 50 MPH WINDS.  ALPHA WEAKENED TO  A TROPICAL
DEPRESSION OVER THE HIGH TERRAIN OF HISPANIOLA...AND IT CONTINUED
NORTHWESTWARD AND NORTHWARD OVER THE SOUTHEASTERN BAHAMAS AND THE
ATLANTIC ON 23 OCTOBER.  THE CYCLONE WEAKENED TO A TROUGH AS IT
APPROACHED THE MUCH LARGER CIRCULATION OF HURRICANE WILMA ON 24
OCTOBER.  ALPHA CAUSED 20 DEATHS IN HISPANIOLA...PRIMARY FROM
FLOODING CAUSED BY HEAVY RAINS.

BETA DEVELOPED OVER THE EXTREME SOUTHWESTERN CARIBBEAN SEA FROM A
TROPICAL WAVE.  A SURFACE LOW PRESSURE SYSTEM FORMED ALONG THE WAVE
AXIS NEAR THE COAST OF COLOMBIA ON 25 OCTOBER.  THE SYSTEM BECAME A
TROPICAL DEPRESSION THE NEXT DAY ABOUT 170 MILES EAST OF THE COSTA
RICA-NICARAGUA BORDER.  THE DEPRESSION MOVED SLOWLY NORTHWARD FOR A
COUPLE OF DAYS...BECOMING A TROPICAL STORM ON 27 OCTOBER.  BETA 
STRENGTHENED INTO A HURRICANE ON 29 OCTOBER NEAR PROVIDENCIA
ISLAND.   IT THEN TURNED WESTWARD AND WEST-SOUTHWESTWARD AND
STRENGTHENED INTO A CATEGORY THREE HURRICANE ON 30 OCTOBER.  BETA
WEAKENED SLIGHTLY LATER THAT DAY AND MADE LANDFALL AS A CATEGORY
TWO HURRICANE ON THE CENTRAL EAST COAST OF NICARAGUA NEAR LA BARRA. 
THE CYCLONE MOVED WESTWARD OVER LAND AND DISSIPATED OVER WESTERN
NICARAGUA EARLY ON 31 OCTOBER. 

BETA CAUSED WIDESPREAD DAMAGE ON PROVIDENCIA ISLAND.  EXTENSIVE
DAMAGE TO STRUCTURES WAS REPORTED ALONG THE CENTRAL NICARAGUAN
COAST.  SIGNIFICANT FLOODING ALSO OCCURRED IN HONDURAS.
