MONTHLY TROPICAL WEATHER SUMMARY
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 AM PDT WED NOV 1 2006
 
FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..
 
FOUR TROPICAL CYCLONES FORMED DURING THE MONTH OF OCTOBER...
TROPICAL STORMS NORMAN AND OLIVIA...HURRICANE PAUL...AND TROPICAL
DEPRESSION EIGHTEEN-E.  ON AVERAGE IN THE EASTERN NORTH PACIFIC
BASIN...TWO TROPICAL STORMS DEVELOP DURING THE MONTH OF OCTOBER...
WITH ONE BECOMING A HURRICANE.

TROPICAL STORM NORMAN ORIGINATED FROM A TROPICAL WAVE THAT REACHED
THE EASTERN NORTH PACIFIC ON 1 OCTOBER.  THE WAVE MOVED WESTWARD
AND FIRST SHOWED SIGNS OF ORGANIZATION ON 8 OCTOBER.  THE SYSTEM
SPAWNED A TROPICAL DEPRESSION ON 9 OCTOBER ABOUT 645 N MI SOUTHWEST
OF CABO SAN LUCAS MEXICO.  THE CYCLONE BECAME A TROPICAL STORM
LATER THAT DAY AS IT MOVED SLOWLY NORTH-NORTHWESTWARD.  NORMAN
REACHED AN ESTIMATED PEAK INTENSITY OF 45 KT ON 10 OCTOBER...THEN
WEAKENED TO A DEPRESSION LATER THAT DAY DUE TO SOUTHWESTERLY
VERTICAL WIND SHEAR.  THE CYCLONE TURNED GENERALLY EASTWARD AND
DEGENERATED TO A NON-CONVECTIVE REMNANT LOW ON 11 OCTOBER ABOUT 
545 N MI SOUTHWEST OF CABO SAN LUCAS.  THE REMNANTS OF NORMAN MOVED
GENERALLY EAST-SOUTHEASTWARD FOR THE NEXT THREE DAYS...BECOMING
INVOLVED WITH A LARGE AREA OF DISTURBED WEATHER NEAR THE COAST OF
MEXICO.  THIS LED TO NORMAN REGENERATING INTO A TROPICAL DEPRESSION
ON 15 OCTOBER ABOUT 80 MILES SOUTHWEST OF MANZANILLO MEXICO.  THE
CYCLONE WAS ABSORBED INTO THE LARGER DISTURBANCE LATER THAT DAY
ABOUT 30 MILES WEST-NORTHWEST OF MANZANILLO.  WHILE THE REGENERATED
NORMAN PRODUCED LOCALLY HEAVY RAINS IN PORTIONS OF SOUTHWESTERN
MEXICO...THERE WERE NO REPORTS OF CASUALTIES OR DAMAGES.

TROPICAL STORM OLIVIA DEVELOPED FROM A WEST-AFRICAN TROPICAL WAVE
THAT MOVED INTO THE EASTERN PACIFIC ON 29 SEPTEMBER.  THE WAVE MOVED
WESTWARD AND DEVELOPED INTO A TROPICAL DEPRESSION LATE ON 9 OCTOBER
ABOUT 1180 N MI WEST-SOUTHWEST OF CABO SAN LUCAS.  SHORTLY
THEREAFTER...THE DEPRESSION TURNED NORTHWARD AND BECAME A TROPICAL
STORM EARLY ON 10 OCTOBER.  OLIVIA THEN MOVED NORTHEASTWARD AND
REACHED AN ESTIMATED PEAK INTENSITY OF 40 KT LATE THAT SAME DAY. 
HOWEVER...INCREASING SOUTHWESTERLY VERTICAL SHEAR INDUCED RAPID
WEAKENING...AND OLIVIA BECAME A DEPRESSION ON 11 OCTOBER ABOUT 905
N MI WEST-SOUTHWEST OF CABO SAN LUCAS.  OLIVIA TURNED EAST-
SOUTHEASTWARD AND GRADUALLY DEGENERATED INTO A REMNANT LOW EARLY ON
13 OCTOBER.  BY 15 OCTOBER ITS REMNANTS WERE ABSORBED BY THE LARGE
DISTURBANCE THAT INCLUDED THE REMNANTS OF NORMAN. THERE WERE NO
REPORTS OF CASUALTIES OR DAMAGES ASSOCIATED WITH OLIVIA.
 
HURRICANE PAUL FORMED FROM A TROPICAL WAVE THAT EMERGED OFF THE
COAST OF AFRICA ON 4 OCTOBER.  THE WAVE CROSSED CENTRAL AMERICA ON
18 OCTOBER AND MOVED INTO A PRE-EXISTING AREA OF DISTURBED WEATHER
OVER THE EASTERN PACIFIC THE NEXT DAY.  THIS RESULTED IN A LARGE
AREA OF DISORGANIZED SHOWERS AND THUNDERSTORMS EXTENDING FROM THE
ITCZ NORTHWARD TO THE SOUTHERN COAST OF MEXICO.  AN AREA OF LOW
PRESSURE DEVELOPED ON 20 OCTOBER...WHICH IS ESTIMATED TO HAVE
BECOME A TROPICAL DEPRESSION EARLY ON 21 OCTOBER ABOUT 230 N MI
SOUTH-SOUTHWEST OF MANZANILLO.  THE DEPRESSION STRENGTHENED INTO A
TROPICAL STORM SHORTLY THEREAFTER. AS PAUL MOVED WESTWARD...
EASTERLY SHEAR PREVENTED FURTHER DEVELOPMENT FOR THE NEXT 24 HOURS. 
PAUL REACHED THE WESTERN END OF THE SUBTROPICAL RIDGE ON 22
OCTOBER...WHERE DECREASING SHEAR ALLOWED RAPID STRENGTHENING.  PAUL
BECAME A HURRICANE ON 23 OCTOBER AND REACHED AN ESTIMATED PEAK
INTENSITY OF 95 KT LATER THAT DAY.  PAUL TURNED NORTH LATE THAT DAY
DUE TO A LARGE TROUGH OFF THE WEST COAST OF THE UNITED STATES...AND 
WESTERLY SHEAR ASSOCIATED WITH THE TROUGH INDUCED WEAKENING.  PAUL
ACCELERATED NORTHEASTWARD ON 24 OCTOBER AS IT WEAKENED INTO A
TROPICAL STORM.  THE CENTER PASSED JUST SOUTH OF CABO SAN LUCAS
MEXICO AS A MINIMAL TROPICAL STORM EARLY ON 25 OCTOBER...THEN
WEAKENED INTO A DEPRESSION LATER THAT DAY.  PAUL TURNED NORTHWARD
WITH A DECREASE IN FORWARD SPEED AS IT APPROACHED THE SOUTHWESTERN
COAST OF MAINLAND MEXICO...THEN MOVED INLAND AND DISSIPATED EARLY
ON 26 OCTOBER NEAR LA REFORMA MEXICO.  REPORTS FROM THE GOVERNMENT
OF MEXICO INDICATE THAT PAUL WAS RESPONSIBLE FOR THREE DEATHS.

TROPICAL DEPRESSION EIGHTEEN-E WAS A SHORT-LIVED TROPICAL CYCLONE
THAT FORMED ABOUT 135 N MI SOUTH OF MANZANILLO ON 26 OCTOBER.  THE
DEPRESSION MOVED SOUTHWESTWARD FOR A DAY OR SO AND ENCOUNTERED
UNFAVORABLE UPPER LEVEL WINDS.  ASSOCIATED THUNDERSTORM ACTIVITY
GRADUALLY DECREASED AND THE SYSTEM BECAME A REMNANT LOW EARLY ON 28
OCTOBER ABOUT 225 N MI SOUTH-SOUTHWEST OF MANZANILLO MEXICO.  THERE
WERE NO REPORTS OF CASUALTIES OR DAMAGE.
