MONTHLY TROPICAL WEATHER SUMMARY
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 AM PDT FRI AUG 1 2008

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

TROPICAL CYCLONE ACTIVITY DURING JULY WAS NEAR AVERAGE.  FOUR
TROPICAL STORMS FORMED DURING THE MONTH.  THREE OF THESE BECAME
HURRICANES BUT NONE BECAME A MAJOR HURRICANE.  IN ADDITION...AT THE
BEGINNING OF THE MONTH HURRICANE BORIS WAS ONGOING AND TROPICAL
DEPRESSION CRISTINA WAS DISSIPATING.  ALSO...ONE TROPICAL
DEPRESSION OCCURRED THAT DID NOT REACH STORM STRENGTH.  ON
AVERAGE...ABOUT FOUR TROPICAL STORMS DEVELOP IN JULY...WITH TWO
BECOMING HURRICANES... AND ONE BECOMING A MAJOR HURRICANE.  SO FAR
THE EASTERN PACIFIC HAS HAD SEVEN TROPICAL STORMS...FOUR
HURRICANES...AND NO MAJOR HURRICANES.  THIS IS PRETTY CLOSE TO THE
LONG-TERM AVERAGE OF SEVEN TROPICAL STORMS...THREE HURRICANES...AND
ONE MAJOR HURRICANE.  2008 HAS ALREADY HAD AS MANY HURRICANES AS
ALL OF 2007 IN THE EASTERN PACIFIC.  

AT THE START OF JULY...BORIS WAS A CATEGORY ONE HURRICANE LOCATED
ABOUT 1140 MILES WEST-SOUTHWEST OF THE SOUTHERN TIP OF BAJA
CALIFORNIA.  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 1420 MILES
WEST-SOUTHWEST OF THE SOUTHERN TIP OF BAJA CALIFORNIA.   

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 AND BEGAN TO WEAKEN. IT BECAME A REMNANT LOW ON 3
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 400 MILES
SOUTHEAST OF ACAPULCO AND BECAME A TROPICAL STORM LATER THAT 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 335 MILES
SOUTH-SOUTHWEST OF CABO CORRIENTES. 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
1570 MILES WEST OF THE SOUTHERN TIP OF BAJA CALIFORNIA. BY 21
JULY...THE WESTWARD-MOVING REMNANT LOW HAD DISSIPATED.

FAUSTO DEVELOPED FROM A TROPICAL WAVE THAT MOVED WESTWARD FROM THE
COAST OF AFRICA ON ON 5 JULY.  THIS SYSTEM SHOWED SIGNS OF
ORGANIZATION UPON REACHING THE EASTERN PACIFIC ON 13 JULY...AND
GRADUAL DEVELOPMENT CONTINUED DURING THE NEXT COUPLE OF DAYS.  A
TROPICAL DEPRESSION FORMED ON 16 JULY ABOUT 560 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 100 MPH EARLY ON 21 JULY.  LATER
THAT DAY...A TURN TOWARD THE WEST-NORTHWEST BROUGHT FAUSTO OVER
COOLER WATERS AND IT QUICKLY WEAKENED TO A TROPICAL STORM. 
ADDITIONAL WEAKENING CAUSED THE CYCLONE TO DECAY TO A REMNANT LOW
ON 22 JULY ABOUT 750 MILES WEST OF THE SOUTHERN TIP OF BAJA
CALIFORNIA.  THE LOW DISSIPATED ON 24 JULY ABOUT 1200 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 DISSIPATING A LITTLE LATER THAT DAY.  GENEVIEVE'S
REMNANT LOW CONTINUED TO MOVE WESTWARD FOR SEVERAL DAYS AND BY
MONTH'S END BECAME INDISTINCT AS IT CROSSED INTO THE CENTRAL
PACIFIC HURRICANE BASIN.
