MONTHLY TROPICAL WEATHER SUMMARY...CORRECTED
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 AM PST MON DEC 1 2008

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

NOVEMBER HAD ONE SHORT-LIVED TROPICAL STORM...POLO.  THE EASTERN
PACIFIC HAS ABOUT ONE NOVEMBER TROPICAL STORM EVERY THREE
YEARS...AND THE LAST TROPICAL CYCLONE TO OCCUR IN NOVEMBER WAS
SERGIO IN 2006.  

OVERALL TROPICAL CYCLONE ACTIVITY DURING THE 2008 EASTERN NORTH
PACIFIC SEASON WAS BELOW AVERAGE. SIXTEEN TROPICAL STORMS
OCCURRED...OF WHICH SEVEN BECAME HURRICANES AND TWO BECAME MAJOR
HURRICANES.  ALTHOUGH THE NUMBER OF TROPICAL STORMS WAS NEAR
AVERAGE...THE NUMBERS OF HURRICANES AND MAJOR HURRICANES WERE BELOW
AVERAGE.  IN TERMS OF THE ACCUMULATED CYCLONE ENERGY (ACE)
INDEX...2008 HAD ABOUT 75% OF THE LONG-TERM MEDIAN VALUE.  MANY OF
THE TROPICAL CYCLONES THIS YEAR EXPERIENCED STRONG EASTERLY
SHEAR...WHICH LED TO SEVERAL WEAK AND SHORT-LIVED STORMS.  HURRICANE
NORBERT AND TROPICAL STORM JULIO MADE LANDFALL IN MEXICO AND 
TROPICAL STORM ALMA MADE LANDFALL ALONG THE PACIFIC COAST OF
NICARAGUA EARLY IN THE SEASON.

ALMA ORIGINATED FROM A BROAD AREA OF LOW PRESSURE THAT FORMED EARLY
ON 27 MAY ABOUT 260 MILES SOUTHWEST OF THE COAST OF NICARAGUA.  THE
LOW SUBSEQUENTLY MOVED SLOWLY EASTWARD.  THE ASSOCIATED SHOWER AND
THUNDERSTORM ACTIVITY BECAME BETTER ORGANIZED...AND EARLY ON 29 MAY
A TROPICAL DEPRESSION FORMED ABOUT 100 MILES WEST-NORTHWEST OF CABO
BLANCO COSTA RICA.  THE DEPRESSION TURNED NORTHWARD AND REACHED
TROPICAL STORM STRENGTH LATER THAT DAY.  ALMA REACHED ITS PEAK
INTENSITY OF 65 MPH WHILE CENTERED ABOUT 50 MILES SOUTHWEST OF
MANAGUA NICARAGUA.  A FEW HOURS LATER...ALMA MADE LANDFALL AT THAT
SAME INTENSITY ALONG THE NORTHWESTERN PACIFIC COAST OF NICARAGUA
NEAR LEON.  AFTER LANDFALL...ALMA CONTINUED NORTHWARD AND WEAKENED
TO A TROPICAL DEPRESSION OVER HONDURAS.  THE LOW-LEVEL CIRCULATION
OF ALMA DISSIPATED OVER THE MOUNTAINS OF WESTERN HONDURAS ON 30
MAY.

ALMA WAS THE FIRST TROPICAL STORM TO MAKE LANDFALL ALONG THE 
PACIFIC COAST OF HONDURAS SINCE RECORDS BEGAN IN 1949.  MEDIA
REPORTS INDICATE THAT ALMA CAUSED TWO FATALITIES...ONE FROM FLOODING
IN NICARAGUA AND ONE WHEN A FISHING VESSEL SANK OFFSHORE.  TWO
OTHER INDIVIDUALS ON THE VESSEL AND SEVEN OTHERS ON ANOTHER BOAT
THAT SANK REMAIN MISSING. 

BORIS FORMED ON 27 JUNE FROM AN AREA OF LOW PRESSURE ASSOCIATED WITH
AN AFRICAN EASTERLY WAVE. THIS WAVE LEFT THE COAST OF WEST AFRICA
ON 14 JUNE...MOVED ACROSS THE TROPICAL NORTH ATLANTIC AS A HIGH
AMPLITUDE DISTURBANCE...AND CROSSED INTO THE EASTERN NORTH PACIFIC
ON 22 JUNE. CONVECTION SLOWLY BECAME ORGANIZED DURING THE NEXT FEW
DAYS AS THE WAVE CONTINUED MOVING SLOWLY WESTWARD. BY EARLY ON 27
JUNE...THE SYSTEM HAD DEVELOPED INTO A TROPICAL DEPRESSION WHEN IT
WAS ABOUT 605 MILES SOUTH-SOUTHWEST OF MANZANILLO MEXICO. LATER
THAT DAY...THE DEPRESSION STRENGTHENED AND REACHED TROPICAL STORM
INTENSITY. BORIS MOVED GENERALLY TOWARD THE WEST DURING THE NEXT
TWO DAYS WITH LITTLE CHANGE IN INTENSITY. ON 29 JUNE...THE CYCLONE
STRENGTHENED TO NEAR HURRICANE INTENSITY WHILE A RAGGED EYE WAS
APPARENT FOR SEVERAL HOURS. BORIS MAINTAINED THAT APPROXIMATE
STRENGTH ON 30 JUNE BEFORE BECOMING A HURRICANE EARLY ON 1 JULY.
ON 2 JULY...BORIS WEAKENED INTO A TROPICAL STORM DUE TO THE EFFECTS
ON COOLER SEA SURFACE TEMPERATURES.  SLOW WEAKENING CONTINUED AND
BORIS BECAME A TROPICAL DEPRESSION ON 3 JULY...DEGENERATING INTO A
REMNANT LOW THE NEXT DAY ABOUT 1460 MILES WEST-SOUTHWEST OF THE
SOUTHERN TIP OF BAJA CALIFORNIA.   

CRISTINA HAD ITS ORIGINS IN A TROPICAL WAVE THAT CROSSED CENTRAL
AMERICA ON 21 JUNE AND MOVED INTO THE EASTERN NORTH PACIFIC BY 22
JUNE.  FOR THE NEXT FEW DAYS...AN AREA OF SHOWERS AND THUNDERSTORMS
ASSOCIATED WITH THE WAVE MOVED WESTWARD WITHIN THE INTERTROPICAL
CONVERGENCE ZONE WITH LITTLE CHANGE IN ORGANIZATION.  BY 26 JUNE
THE CLOUD PATTERN ASSOCIATED WITH THE SYSTEM BEGAN TO BECOME BETTER
ORGANIZED...AND A DEPRESSION FORMED ON 27 JUNE ABOUT 1050 MILES
SOUTHWEST OF THE SOUTHERN TIP OF BAJA CALIFORNIA.  THE TROPICAL
CYCLONE INITIALLY MOVED WEST-NORTHWESTWARD AND STRENGTHENED INTO A
TROPICAL STORM ON 28 JUNE WHILE TURNING WESTWARD.  CRISTINA REACHED
AN INTENSITY OF 50 MPH EARLY ON 29 JUNE.  THE SYSTEM THEN BEGAN TO
LOSE STRENGTH IN A LESS FAVORABLE ENVIRONMENT.  CRISTINA WEAKENED
TO A DEPRESSION ON 30 JUNE...AND DEGENERATED INTO A REMNANT LOW BY
1 JULY.  THE SYSTEM DRIFTED SOUTHWESTWARD FOR A COUPLE OF DAYS
BEFORE LOSING ITS IDENTITY.

DOUGLAS WAS A WEAK...SHORT-LIVED TROPICAL CYCLONE THAT FORMED FROM
AN AREA OF LOW PRESSURE ON 1 JULY ABOUT 280 MILES SOUTHWEST OF
MANZANILLO MEXICO.  DOUGLAS MOVED TOWARD THE NORTHWEST PARALLELING
THE SOUTHWESTERN COAST OF MEXICO WHERE IT PRODUCED HEAVY RAINS. THE
CYCLONE REACHED ITS MAXIMUM INTENSITY OF 40 MPH BEFORE MOVING OVER
COOLER WATERS WHERE IT BEGAN TO WEAKEN. IT BECAME A REMNANT LOW ON 4
JULY.

TROPICAL DEPRESSION FIVE-E WAS A SHORT-LIVED TROPICAL CYCLONE THAT
FORMED FROM A TROPICAL WAVE ON 5 JULY ABOUT 170 MILES
SOUTH-SOUTHEAST OF ACAPULCO MEXICO.  THE CYCLONE INITIALLY MOVED
NORTHWESTWARD BUT TURNED NORTH-NORTHWESTWARD THE NEXT DAY AND
SLOWED DOWN.  A VERY LARGE AREA OF SHOWERS AND THUNDERSTORMS
ACCOMPANIED THE DEPRESSION ON 6 JULY...BUT MOST OF THAT ACTIVITY
REMAINED OFFSHORE FROM MEXICO UNTIL LATE THAT DAY.  CONTINUING
SLOWLY NORTHWARD...THE CENTER OF THE DEPRESSION MADE LANDFALL VERY
EARLY ON 7 JULY JUST WEST OF LAZARO CARDENAS MEXICO WITH MAXIMUM
WINDS OF ABOUT 35 MPH...AND THE CIRCULATION DISSIPATED INLAND OVER
MOUNTAINOUS TERRAIN A FEW HOURS LATER.  HEAVY RAINS WERE DUMPED AT
SOME LOCATIONS ALONG THE COAST OF MEXICO...INCLUDING MORE THAN FIVE
AND A HALF INCHES AT MANZANILLO...BUT NO CASUALTIES...FLOODS...OR
OTHER SIGNIFICANT IMPACTS HAVE BEEN REPORTED.

ELIDA WAS A CATEGORY TWO HURRICANE THAT DID NOT AFFECT LAND. IT
FIRST FORMED AS A TROPICAL DEPRESSION ON 11 JULY ABOUT 360 MILES
SOUTH-SOUTHEAST OF ACAPULCO AND BECAME A TROPICAL STORM THE NEXT
DAY. ELIDA MOVED WEST-NORTHWESTWARD ON A TRACK ROUGHLY PARALLEL TO
THE PACIFIC COAST OF MEXICO WHILE GRADUALLY STRENGTHENING OVER THE
NEXT COUPLE OF DAYS...BECOMING A HURRICANE ON 14 JULY ABOUT 345
MILES SOUTHWEST OF MANZANILLO. ELIDA TURNED WESTWARD...AND VERY
LITTLE ADDITIONAL STRENGTHENING OCCURRED OVER THE NEXT TWO DAYS
WHILE THE CYCLONE EXPERIENCED SOME EASTERLY VERTICAL WIND SHEAR. BY
16 JULY THIS SHEAR HAD DIMINISHED...AND ELIDA BEGAN TO
STRENGTHEN...REACHING ITS PEAK INTENSITY OF 105 MPH...SHORTLY
BEFORE THE CENTER OF THE HURRICANE REACHED COOLER WATERS. GRADUAL
WEAKENING BEGAN THE NEXT DAY...AND ELIDA BECAME A TROPICAL STORM ON
18 JULY AND A DEPRESSION ON 19 JULY. LACKING ORGANIZED THUNDERSTORM
ACTIVITY...ELIDA DEGENERATED TO A REMNANT LOW LATER THAT DAY ABOUT
1500 MILES EAST OF THE HAWAIIAN ISLANDS. BY 22 JULY...THE
WESTWARD-MOVING REMNANT LOW HAD DISSIPATED.

FAUSTO DEVELOPED FROM A TROPICAL WAVE THAT MOVED WESTWARD FROM THE
COAST OF AFRICA ON 4 JULY.  THIS SYSTEM SHOWED SIGNS OF ORGANIZATION
UPON REACHING THE EASTERN PACIFIC ON 13 JULY...AND SLOW DEVELOPMENT
OCCURRED DURING THE NEXT COUPLE OF DAYS.  A TROPICAL DEPRESSION
FORMED ON 16 JULY ABOUT 550 MILES SOUTHEAST OF ACAPULCO...AND THE
CYCLONE REACHED TROPICAL STORM STRENGTH LATER THAT DAY.  AFTER AN
INITIAL WESTWARD MOTION...FAUSTO MOVED WEST-NORTHWESTWARD...
BECOMING A HURRICANE ON 18 JULY.  THE HURRICANE THEN TURNED
NORTHWESTWARD AND UNSTEADILY STRENGTHENED TO AN ESTIMATED PEAK
INTENSITY OF 90 MPH ON 20 JULY.  THE NEXT DAY...A TURN TOWARD THE
WEST-NORTHWEST BROUGHT FAUSTO OVER COOLER WATERS AND IT WEAKENED TO
A TROPICAL STORM.  ADDITIONAL WEAKENING CAUSED THE CYCLONE TO DECAY
TO A REMNANT LOW EARLY ON 23 JULY ABOUT 765 MILES WEST OF THE
SOUTHERN TIP OF BAJA CALIFORNIA.  THE LOW DISSIPATED ON 24 JULY
ABOUT 1050 MILES WEST OF THE SOUTHERN TIP OF BAJA CALIFORNIA.

GENEVIEVE DEVELOPED FROM A TROPICAL WAVE THAT ALMOST PRODUCED AN
ATLANTIC TROPICAL DEPRESSION NEAR THE COAST OF NICARAGUA ON 17
JULY.  THE WAVE MOVED WESTWARD INTO THE PACIFIC ON 18 JULY AND THE
ASSOCIATED CLOUDINESS AND THUNDERSTORMS SHOWED SIGNS OF
ORGANIZATION AS THE SYSTEM MOVED WESTWARD TO THE SOUTH OF CENTRAL
AMERICA AND MEXICO ON 19-20 JULY.  THE DISTURBANCE EVOLVED INTO A
TROPICAL DEPRESSION ON 21 JULY ABOUT 250 MILES SOUTH-SOUTHWEST OF
ACAPULCO AND INTENSIFIED INTO A TROPICAL STORM LATER THAT DAY.  OVER
THE NEXT FEW DAYS...GENEVIEVE MOVED ON A WESTWARD TO
WEST-NORTHWESTWARD TRACK WITH SOME FLUCTUATIONS IN STRENGTH.  IT
EVENTUALLY BECAME A HURRICANE ON 25 JULY WHILE LOCATED ABOUT 575
MILES SOUTHWEST OF CABO SAN LUCAS MEXICO. GENEVIEVE WEAKENED BACK
TO A TROPICAL STORM BY EARLY THE FOLLOWING DAY.  THE WESTWARD-
MOVING CYCLONE CONTINUED TO SPIN DOWN...BECOMING A DEPRESSION EARLY
ON 27 JULY AND DEGENERATING TO A REMNANT LOW A LITTLE LATER THAT
DAY.  GENEVIEVE'S REMNANT LOW CONTINUED TO MOVE WESTWARD FOR
SEVERAL DAYS.

HERNAN DEVELOPED FROM A TROPICAL WAVE THAT DEPARTED THE WEST COAST
OF AFRICA ON 24 JULY AND ENTERED THE EASTERN NORTH PACIFIC OCEAN ON
2 AUGUST. THE WAVE SPAWNED A BROAD AREA OF LOW PRESSURE ABOUT 600
MILES SOUTH OF MANZANILLO MEXICO ON 5 AUGUST. THE NEXT DAY...
THE LOW BECAME A TROPICAL DEPRESSION ABOUT 775 MILES SOUTH-SOUTHWEST
OF THE SOUTHERN TIP OF BAJA CALIFORNIA. THE DEPRESSION STRENGTHENED
INTO A TROPICAL STORM TWELVE HOURS LATER. HERNAN INITIALLY MOVED
WEST-NORTHWESTWARD WHILE GRADUALLY STRENGTHENING OVER THE OPEN
WATERS OF THE EASTERN PACIFIC. BY 8 AUGUST...HERNAN TURNED WESTWARD
AND REACHED HURRICANE STRENGTH ABOUT 900 MILES SOUTHWEST OF THE
SOUTHERN TIP OF BAJA CALIFORNIA. OVER THE NEXT DAY OR SO...HERNAN
MOVED WEST-NORTHWESTWARD AND CONTINUED TO STRENGTHEN...REACHING A 
A PEAK INTENSITY OF 120 MPH AT 1200 UTC 9 AUGUST. SHORTLY
THEREAFTER...THE HURRICANE MOVED OVER COOLER WATERS WHICH INITIATED
WEAKENING...AND HERNAN BECOME A TROPICAL STORM EARLY ON 12 AUGUST.
THE STORM TURNED WESTWARD TO WEST-SOUTHWESTWARD AND ASSOCIATED
THUNDERSTORM ACTIVITY DIMINISHED THAT DAY. HERNAN DEGENERATED INTO
A REMNANT LOW PRESSURE SYSTEM BY 13 AUGUST WHILE LOCATED 
1600 MILES WEST-SOUTHWEST OF BAJA CALIFORNIA. THE REMNANT LOW
CONTINUED MOVING WEST-SOUTHWESTWARD AND EVENTUALLY DISSIPATED ABOUT
450 MILES SOUTHEAST OF THE HAWAIIAN ISLANDS ON 16 AUGUST. THERE ARE
NO REPORTS OF CASUALTIES OR DAMAGE ASSOCIATED WITH HERNAN.

ISELLE WAS A RELATIVELY SHORT-LIVED TROPICAL STORM THAT DID NOT
THREATEN LAND. ISELLE DEVELOPED AS A DEPRESSION ON 13 AUGUST ABOUT
210 MILES SOUTH-SOUTHWEST OF MANZANILLO MEXICO AND BECAME A
TROPICAL STORM SIX HOURS LATER. HOWEVER...STRONG UPPER-LEVEL WINDS
INHIBITED STRENGTHENING THROUGHOUT ISELLE'S LIFETIME...AND THE
CYCLONE PEAKED EARLY ON 15 AUGUST WITH 50 MPH WINDS WHEN IT WAS
ABOUT 355 MILES SOUTH OF THE SOUTHERN TIP OF BAJA CALIFORNIA.
CONTINUING WESTWARD BENEATH HOSTILE UPPER-LEVEL EASTERLY SHEAR
CONDITIONS...ISELLE WEAKENED TO A TROPICAL DEPRESSION ON 16
AUGUST...AND DEGENERATED INTO A NON-CONVECTIVE REMNANT LOW PRESSURE
SYSTEM EARLY THE NEXT DAY ABOUT 350 MILES SOUTH-SOUTHWEST OF THE
SOUTHERN TIP OF BAJA CALIFORNIA. THE REMNANT LOW CONTINUED SLOWLY
WESTWARD FOR THE NEXT TWO DAYS BEFORE TURNING SHARPLY SOUTHWESTWARD
ON 19 AUGUST. THE LOW DISSIPATED THREE DAYS LATER ON 22 AUGUST
ABOUT 1200 MILES SOUTHWEST OF THE SOUTHERN TIP OF BAJA CALIFORNIA.
THERE ARE NO REPORTS OF CASUALTIES OR DAMAGE.

JULIO FORMED ABOUT 375 MILES SOUTH-SOUTHEAST OF THE SOUTHERN TIP OF
BAJA CALIFORNIA ON 23 AUGUST.  THE TROPICAL DEPRESSION QUICKLY
INTENSIFIED INTO A TROPICAL STORM AND MOVED NORTHWESTWARD TO
NORTH-NORTHWESTWARD.  JULIO REACHED ITS PEAK INTENSITY OF 50 MPH ON
24 AUGUST AS ITS CENTER NEARED CABO SAN LUCAS MEXICO.  LATER THAT
DAY...THE STORM MADE LANDFALL NEAR CABO SAN LUCAS. JULIO MOVED
ALONG THE SOUTHERN AND CENTRAL BAJA CALIFORNIA PENINSULA OVER THE
NEXT DAY OR SO WHILE VERY SLOWLY LOSING STRENGTH. HOWEVER...THE
CYCLONE PRODUCED LOCALLY HEAVY RAINFALL ACROSS THE BAJA PENINSULA. 
JULIO WEAKENED TO A TROPICAL DEPRESSION EARLY ON 26 AUGUST AND
DISSIPATED OVER THE GULF OF CALIFORNIA LATER THAT DAY.  MEDIA
REPORTS OF CASUALTIES HAVE NOT YET BEEN CONFIRMED.  THERE ARE
NO REPORTS OF SIGNIFICANT DAMAGE.

KARINA WAS A SHORT-LIVED TROPICAL CYCLONE. A TROPICAL DEPRESSION
FORMED 260 MILES SOUTH OF THE SOUTHERN TIP OF BAJA CALIFORNIA EARLY
ON 2 SEPTEMBER FROM A PERSISTENT AREA OF DISTURBED WEATHER. KARINA
WAS EMBEDDED WITHIN A STRONG SHEARING ENVIRONMENT...ALTHOUGH IT WAS
ABLE TO REACH AN INTENSITY OF 40 MPH LATE ON 2 SEPTEMBER.
THEREAFTER...THE SHEAR INCREASED FURTHER AND KARINA DEGENERATED TO
A REMNANT LOW LATE ON 3 SEPTEMBER.

LOWELL FORMED FROM A STRONG TROPICAL DISTURBANCE EARLY ON 7
SEPTEMBER WHILE IT WAS LOCATED ABOUT 265 MILES SOUTH-SOUTHWEST OF
MANZANILLO MEXICO. DESPITE BEING UNDER THE INFLUENCE OF
NORTHEASTERLY SHEAR...THE STORM GRADUALLY STRENGTHENED OVER THE
NEXT DAY AND REACHED A PEAK INTENSITY OF 60 MPH WHEN IT WAS LOCATED
ABOUT 325 MILES SOUTH OF THE SOUTHERN TIP OF BAJA CALIFORNIA.
LOWELL CONTINUED TO MOVE NORTHWESTWARD WELL OFF THE COAST OF MEXICO
BUT STARTED TO WEAKEN ON 9 SEPTEMBER AS IT BEGAN TO INGEST STABLE
AIR AND REMAINED UNDER THE INFLUENCE OF NORTHEASTERLY SHEAR. THE
CYCLONE ULTIMATELY WEAKENED TO A TROPICAL DEPRESSION ON 10
SEPTEMBER AND TURNED SLOWLY TO THE NORTHEAST IN RESPONSE TO A
MID-LATITUDE TROUGH TO ITS NORTH. LOWELL MADE LANDFALL OVER THE FAR
SOUTHERN BAJA PENINSULA EARLY ON 11 SEPTEMBER...MOVED ACROSS THE
GULF OF CALIFORNIA...THEN DISSIPATED ALONG THE COAST OF MAINLAND
MEXICO NEAR LOS MOCHIS EARLY ON 12 SEPTEMBER. ALTHOUGH NO DEATHS
HAVE BEEN REPORTED...HEAVY RAINFALL AND FLOODING FROM THE REMNANTS
OF LOWELL LEFT MORE THAN 26500 PEOPLE HOMELESS IN THE MEXICAN
STATES OF MICHOACAN...SONORA...AND SINALOA.

MARIE DEVELOPED FROM A TROPICAL WAVE...THAT WAS ACCOMPANIED BY A LOW
PRESSURE SYSTEM...EARLY ON 1 OCTOBER ABOUT 585 MILES SOUTHWEST OF
THE SOUTHERN TIP OF BAJA CALIFORNIA. WHILE MOVING IN A GENERAL
WESTERLY DIRECTION...THE DEPRESSION STRENGTHENED INTO A TROPICAL
STORM LATER THAT DAY. AFTER TURNING WEST-SOUTHWESTWARD...MARIE
BECAME A HURRICANE LATE ON 3 OCTOBER ABOUT 870 MILES WEST-SOUTHWEST
OF BAJA CALIFORNIA. AFTER MARIE REACHED ITS PEAK INTENSITY ON 4
OCTOBER...STEADY WEAKENING OCCURRED UNTIL THE CYCLONE DEGENERATED
INTO A REMNANT LOW PRESSURE SYSTEM ON 7 OCTOBER ABOUT 990 MILES
WEST-SOUTHWEST OF BAJA CALIFORNIA. MARIE LASTED LONGER AS A REMNANT
LOW THAN IT DID AS A TROPICAL CYCLONE. AFTER MOVING SOUTHWESTWARD
FOR THE NEXT 12 DAYS...THE SYSTEM WAS FINALLY ABSORBED INTO THE
INTERTROPICAL CONVERGENCE ZONE ON 19 OCTOBER ABOUT 1200 MILES
EAST-SOUTHEAST OF THE HAWAIIAN ISLANDS.

NORBERT FORMED OUT OF A BROAD AND NEARLY STATIONARY AREA OF LOW
PRESSURE...BECOMING A DEPRESSION ON 4 OCTOBER ABOUT 230 MILES SOUTH
OF ACAPULCO MEXICO.  IT MOVED LITTLE INITIALLY...BUT BUILDING HIGH
PRESSURE TO THE NORTH OF THE CYCLONE INDUCED A WESTWARD TRACK BY
LATE THAT DAY.  THE SYSTEM BECAME A TROPICAL STORM ON 5 OCTOBER AND
SLOWLY STRENGTHENED...REACHING HURRICANE STRENGTH ON 7 OCTOBER
ABOUT 315 MILES SOUTH-SOUTHWEST OF MANZANILLO MEXICO.  NORBERT
CONTINUED TO STRENGTHEN AS IT MOVED WEST-NORTHWESTWARD...REACHING A
PEAK INTENSITY OF 135 MPH...CATEGORY FOUR ON THE SAFFIR-SIMPSON
SCALE...ON 8 OCTOBER ABOUT 445 MILES SOUTH OF THE SOUTHERN TIP OF
BAJA CALIFORNIA.  NORBERT THEN TURNED NORTHWESTWARD AND WEAKENED TO
A CATEGORY ONE HURRICANE THE FOLLOWING DAY.  RECURVING AHEAD OF A
DEEP-LAYER TROUGH...NORBERT TURNED NORTH-NORTHEASTWARD TOWARD THE
BAJA CALIFORNIA PENINSULA...BRIEFLY REGAINING MAJOR HURRICANE
STATUS ON 11 OCTOBER.  NORBERT MADE LANDFALL NEAR PUERTO CHARLEY ON
THE WEST COAST OF THE PENINSULA AROUND 1630 UTC 11 OCTOBER AS A
CATEGORY TWO HURRICANE...WITH MAXIMUM WINDS ESTIMATED AT 105 MPH. 
MOVING NORTHEASTWARD...NORBERT CROSSED THE PENINSULA AND MADE A
SECOND LANDFALL IN MAINLAND MEXICO ABOUT 25 MILES SOUTHEAST OF
HUATABAMPO AROUND 0400 UTC 12 OCTOBER WITH MAXIMUM WINDS NEAR 85
MPH...CATEGORY ONE STRENGTH.  NORBERT WEAKENED RAPIDLY AFTER
LANDFALL AND DISSIPATED OVER THE MOUNTAINS OF MEXICO LATER THAT
DAY.  INFORMATION ON DAMAGE AND CASUALTIES IS STILL BEING COMPILED.

TROPICAL STORM ODILE HAD A COMPLEX ORIGIN...WITH TWO TROPICAL WAVES
AND THE REMAINS OF A FRONTAL SYSTEM INVOLVED IN THE INITIAL
DEVELOPMENT.  THE DISTURBANCE THAT BECAME ODILE REACHED THE EASTERN
PACIFIC ON 4 OCTOBER AND ALMOST IMMEDIATELY SHOWED SIGNS OF
ORGANIZATION.  HOWEVER...EASTERLY VERTICAL WIND SHEAR STOPPED
DEVELOPMENT THE NEXT DAY AS THE SYSTEM STALLED SOUTH OF EL
SALVADOR.  LITTLE MOTION OR CHANGE IN ORGANIZATION OCCURRED DURING
THE NEXT COUPLE OF DAYS.  DEVELOPMENT RESUMED ON 8 OCTOBER...AND A
TROPICAL DEPRESSION FORMED THAT DAY ABOUT 120 MILES SOUTH-SOUTHWEST
OF SAN SALVADOR EL SALVADOR.  THE CYCLONE MOVED WEST-NORTHWESTWARD
AND BECAME A TROPICAL STORM ON 9 OCTOBER.  THE STORM TURNED
NORTHWESTWARD ON 10 OCTOBER...THEN IT MOVED WEST-NORTHWESTWARD
NEAR THE SOUTHWESTERN COAST OF MEXICO ON 11 OCTOBER.  ODILE REACHED
AN ESTIMATED PEAK INTENSITY OF 60 MPH ON 10 OCTOBER.  SOUTHEASTERLY
VERTICAL WIND SHEAR CAUSE THE STORM TO WEAKEN THE NEXT DAY...AND IT
WEAKENED TO A DEPRESSION EARLY ON 12 OCTOBER.  THE CYCLONE
DEGENERATED TO A REMNANT LOW EARLY ON 13 OCTOBER ABOUT 50 MILES
SOUTH OF MANZANILLO MEXICO.  THE LOW MOVED SLOWLY SOUTHWESTWARD
BEFORE DISSIPATING LATER THAT DAY.

WHILE ODILE WAS CLOSE ENOUGH TO THE COAST OF MEXICO TO REQUIRE
WATCHES AND WARNINGS...THERE ARE NO REPORTS OF DAMAGE OR
CASUALTIES.

TROPICAL DEPRESSION SEVENTEEN-E ORIGINATED FROM A REGION OF
CONVECTION THAT DEVELOPED SOUTH OF THE GULF OF TEHUANTEPEC ON 20
OCTOBER IN ASSOCIATION WITH A SLOW-MOVING TROPICAL WAVE THAT MOVED
INTO THE REGION AFTER EMERGING FROM THE WEST COAST OF AFRICA ON 30
SEPTEMBER.  A TROPICAL DEPRESSION FORMED ON 23 OCTOBER ABOUT 470
MILES SOUTH OF MANZANILLO MEXICO.  THE DEPRESSION INITIALLY MOVED
NORTHWARD AND THEN TURNED TOWARD THE NORTHWEST EARLY ON 24
OCTOBER...REMAINING WELL OFFSHORE DURING ITS SHORT LIFESPAN. 
STRONG VERTICAL WIND SHEAR HINDERED ANY FURTHER DEVELOPMENT OF THE
DEPRESSION...WHICH HAD A PEAK INTENSITY OF 35 MPH.  THE STRONG
UPPER-LEVEL WINDS BROUGHT RAINFALL FROM THE DEPRESSION TO THE
SOUTHWESTERN COAST OF MEXICO ON 24 OCTOBER...AND ULTIMATELY LED TO
THE DEGENERATION OF THE DEPRESSION INTO A REMNANT LOW LATE ON 24
OCTOBER ABOUT 280 MILES SOUTH-SOUTHWEST OF MANZANILLO.  THE REMNANT
LOW MOVED TOWARD THE WEST-NORTHWEST AND WEST UNTIL IT DISSIPATED
EARLY ON 28 OCTOBER ABOUT 690 MILES SOUTHWEST OF THE SOUTHERN TIP
OF BAJA CALIFORNIA. 

POLO WAS A SHORT-LIVED LOW-LATITUDE TROPICAL CYCLONE THAT FORMED
FROM A TROPICAL WAVE ALONG THE INTERTROPICAL CONVERGENCE ZONE.  THE
TROPICAL DEPRESSION FIRST FORMED ON 2 NOVEMBER ABOUT 810 MILES
SOUTH-SOUTHWEST OF MANZANILLO MEXICO AND THEN STRENGTHENED TO A
TROPICAL STORM EARLY ON 3 NOVEMBER AS THUNDERSTORM ACTIVITY
DEVELOPED AROUND A SMALL CENTER.  POLO REACHED A PEAK INTENSITY OF
40 MPH BEFORE DEGENERATING INTO AN OPEN TROUGH EARLY ON 5 NOVEMBER
ABOUT 1130 MILES SOUTHWEST OF THE SOUTHERN TIP OF BAJA CALIFORNIA.
