MONTHLY TROPICAL WEATHER SUMMARY
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 AM PDT THU NOV 1 2007

FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..

ONLY ONE TROPICAL STORM...KIKO...FORMED IN THE EASTERN NORTH PACIFIC
DURING THE MONTH OF OCTOBER.  THIS IS BELOW THE CLIMATOLOGICAL MEAN
OF TWO TROPICAL STORMS DEVELOPING DURING THE MONTH OF OCTOBER...WITH
ONE BECOMING A HURRICANE.  SO FAR...2007 IS THE SECOND QUIETEST
SEASON (BASED ON RELIABLE RECORDS SINCE 1971) BEHIND 1977 IN TERMS
OF ACE...ACCUMULATED CYCLONE ENERGY...WHICH IS A MEASURE OF THE
STRENGTH AND DURATION OF NAMED STORMS AND HURRICANES.
JULIETTE...A SEPTEMBER TROPICAL STORM...DISSIPATED EARLY IN
OCTOBER.

JULIETTE FORMED FROM A TROPICAL WAVE THAT MOVED OFF THE COAST OF
WEST AFRICA ON 12 SEPTEMBER AND ENTERED THE EASTERN PACIFIC OCEAN
ON 23 SEPTEMBER.  SHOWERS AND THUNDERSTORMS ASSOCIATED WITH THE
WAVE GRADUALLY BECAME BETTER ORGANIZED AND AN AREA OF LOW PRESSURE
FORMED ON 27 SEPTEMBER APPROXIMATELY 300 N MI SOUTHWEST OF ACAPULCO
MEXICO.  CONVECTION CONTINUED TO BECOME BETTER ORGANIZED AND A
DEPRESSION IS ESTIMATED TO HAVE FORMED AT 0000 UTC 29 SEPTEMBER
APPROXIMATELY 365 N MI SOUTHWEST OF MANZANILLO MEXICO.  THE
DEPRESSION INTENSIFIED TO A TROPICAL STORM...THE TENTH OF THE 2007
EASTERN PACIFIC SEASON...LATER THAT DAY AND REACHED ITS PEAK
INTENSITY OF 45 KT AT 1200 UTC 30 SEPTEMBER. THEREAFTER...STRONG
VERTICAL SHEAR...COOLER SSTS...AND A MORE STABLE AIR MASS RESULTED
IN WEAKENING AND JULIETTE QUICKLY DEGENERATED INTO A REMNANT LOW AT
1200 UTC 2 OCTOBER.

KIKO ORIGINATED FROM THE SAME TROPICAL WAVE THAT SPAWNED TROPICAL
STORM MELISSA OVER THE EASTERN TROPICAL ATLANTIC OCEAN.  THE WAVE
CONTINUED WESTWARD AND ENTERED THE EASTERN PACIFIC ON 8 OCTOBER.
AN AREA OF LOW PRESSURE...ACCOMPANIED BY SHOWERS AND
THUNDERSTORMS...DEVELOPED ALONG THE WAVE AXIS AND THE SYSTEM
EVENTUALLY ACQUIRED ENOUGH ORGANIZATION TO BE CLASSIFIED AS A
TROPICAL DEPRESSION EARLY ON 15 OCTOBER...WHILE CENTERED ABOUT 350 N
MI SOUTHWEST OF MANZANILLO MEXICO.  THE DEPRESSION DRIFTED
SOUTHWARD FOR A LITTLE OVER A DAY.  IT BRIEFLY BECAME A TROPICAL
STORM ON OCTOBER 16...BUT WEAKENED BACK TO A DEPRESSION SHORTLY
THEREAFTER.  THE CYCLONE MOVED EASTWARD AND EAST- NORTHEASTWARD
WITH A SLOWLY INCREASING FORWARD SPEED.  KIKO BECAME A TROPICAL
STORM...ONCE AGAIN...EARLY ON 17 OCTOBER WHILE CENTERED ABOUT 335 N
MI SOUTH-SOUTHWEST OF MANZANILLO.  FOR THE NEXT DAY OR TWO...KIKO
MOVED TOWARD THE EAST-NORTHEAST AS A MINIMAL STORM...TOWARD THE
SOUTHWESTERN COAST OF MEXICO.  BY EARLY ON 19 OCTOBER...KIKO TURNED
TOWARD THE NORTHWEST AS A RIDGE DEVELOPED OVER MEXICO.  DURING THE
NEXT COUPLE OF DAYS...KIKO MOVED SLOWLY TOWARD THE NORTHWEST AND
GRADUALLY STRENGTHENED...AND REACHED ITS MAXIMUM INTENSITY OF 60 KT
AROUND ON 20 OCTOBER WHILE CENTERED ABOUT 150 N MI WEST-SOUTHWEST
OF MANZANILLO.  KIKO GRADUALLY WEAKENED DUE TO BOTH INCREASING
SOUTHERLY SHEAR AND A MORE STABLE ENVIRONMENT AND BECAME A TROPICAL
DEPRESSION ON 22 OCTOBER.  THE DEPRESSION MOVED WESTWARD AND
DEGENERATED INTO A REMNANT LOW EARLY ON 24 OCTOBER. THE REMNANT LOW
CONTINUED TO MOVE GENERALLY WESTWARD FOR THE NEXT COUPLE OF DAYS
WITHIN THE LOW-LEVEL STEERING FLOW THEN TURNED NORTHWARD BEFORE
DISSIPATING EARLY ON 27 OCTOBER.
