TROPICAL WEATHER SUMMARY FOR THE CENTRAL NORTH PACIFIC
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
500 AM HST SAT OCT 01 2005

FOR THE CENTRAL NORTH PACIFIC...BETWEEN 140W AND 180

THERE WERE TWO HURRICANES IN THE CENTRAL PACIFIC HURRICANE CENTER 
AREA OF RESPONSIBILITY DURING THE MONTH OF SEPTEMBER 2005.

THE FIRST ADVISORY FOR HURRICANE JOVA WAS ISSUED BY THE CENTRAL 
PACIFIC HURRICANE CENTER AT 1100 PM HST ON SEPTEMBER 17 AS IT MOVED 
WESTWARD ACROSS LONGITUDE 140W. PRIOR TO THAT TIME...THE TROPICAL 
PREDICTION CENTER /TPC/ IN MIAMI...FLORIDA HAD ISSUED ADVISORIES ON 
THIS TROPICAL CYCLONE SINCE SEPTEMBER 10. JOVA HAD MAXIMUM SUSTAINED 
WINDS OF 90 KT...OR 105 MPH...WHEN IT ENTERED THE CENTRAL PACIFIC. 
THE HURRICANE BEGAN TO INTENSIFY AS IT MOVED TOWARD THE WEST- 
NORTHWEST AT 7 TO 10 MPH DURING THE NEXT COUPLE OF DAYS. IN FACT...A 
WELL DEFINED EYE DEVELOPED BY SEPTEMBER 19...AND JOVA/S SUSTAINED 
WINDS INCREASED TO 100 KT...OR 115 MPH. JOVA REMAINED A CATEGORY III 
HURRICANE ON THE SAFFIR-SIMPSON SCALE UNTIL SEPTEMBER 21 WHEN IT 
BEGAN TO ENCOUNTER AN INCREASINGLY HOSTILE ENVIRONMENT FAR EAST OF 
THE HAWAIIAN ISLANDS. STRONG UPPER LEVEL WINDS PRODUCED SIGNIFICANT 
VERTICAL WIND SHEAR AND THE HURRICANE MOVED ACROSS COOLER SEA 
SURFACE TEMPERATURES. JOVA WEAKENED RAPIDLY AS ITS DEEP CONVECTION 
BECAME DISPLACED AWAY FROM THE CENTER. THE SYSTEM WAS DOWNGRADED TO 
A TROPICAL STORM AT 500 PM HST ON SEPTEMBER 22. JOVA CONTINUED TO 
WEAKEN DURING THE NEXT DAY...AND WAS DOWNGRADED TO A TROPICAL 
DEPRESSION 24 HOURS LATER. THE FINAL BULLETIN WAS ISSUED FOR 
TROPICAL DEPRESSION JOVA AT 500 PM HST ON SEPTEMBER 24. NO REPORTS 
OF DEATHS OR PROPERTY DAMAGE IN THE CENTRAL PACIFIC DIRECTLY 
ATTRIBUTABLE TO HURRICANE JOVA WERE RECEIVED. HOWEVER...SWELLS 
GENERATED BY THE HURRICANE PRODUCED HIGH SURF ALONG THE EAST FACING 
SHORES OF THE HAWAIIAN ISLANDS...ESPECIALLY ALONG THE WINDWARD AND 
SOUTHEASTERN FACING BEACHES OF THE BIG ISLAND. MOISTURE FROM THE 
REMNANTS OF JOVA ALSO MOVED ACROSS THE HAWAIIAN ISLANDS AND LIKELY 
CONTRIBUTED TO SOME LOCAL FLOODING...ESPECIALLY ON OAHU DURING THE 
AFTERNOON AND EARLY EVENING OF SEPTEMBER 24.

THE FIRST ADVISORY FOR HURRICANE KENNETH WAS ISSUED BY THE CENTRAL 
PACIFIC HURRICANE CENTER AT 1100 PM HST ON SEPTEMBER 25 AFTER IT 
RELUCTANTLY CROSSED 140W. BEFORE THAT...THE TPC HAD BEEN ISSUING 
ADVISORIES ON THIS TROPICAL CYCLONE IN THE EAST PACIFIC SINCE 
SEPTEMBER 13. KENNETH HAD MAXIMUM SUSTAINED WINDS OF 65 KT...OR 75 
MPH...WHEN IT ENTERED THE CENTRAL PACIFIC. HOWEVER...THE HURRICANE 
IMMEDIATELY BEGAN TO WEAKEN...AND WAS DOWNGRADED TO A TROPICAL STORM 
6 HOURS LATER WITH MAXIMUM SUSTAINED WINDS OF 60 KT...OR 70 MPH. 
INCREASING VERTICAL WIND SHEAR WAS THE LIKELY REASON FOR THIS 
WEAKENING. TROPICAL STORM KENNETH CHURNED SLOWLY SOUTHWESTWARD 
DURING THE NEXT DAY...BEFORE TURNING TOWARD THE WEST-NORTHWEST AT 
ABOUT 10 MPH EARLY ON SEPTEMBER 27. KENNETH HAD MAXIMUM SUSTAINED 
WINDS OF 50 KT...OR 60 MPH AT THE SAME TIME...BUT THESE WINDS 
DIMINISHED TO 45 KT...OR 55 MPH...LATER THAT MORNING. THE VERTICAL 
WIND SHEAR BECAME EVEN MORE HOSTILE DURING THE NEXT DAY...AND BY 500 
AM HST SEPTEMBER 28...KENNETH BECAME A TROPICAL DEPRESSION. THIS 
WEAKENING SWIRL OF LOW CLOUDS MOVED WESTWARD AT ABOUT 12 MPH AND 
DISSIPATED JUST EAST OF THE BIG ISLAND AFTER 1100 AM HST SEPTEMBER 
30. NO REPORTS OF DEATHS OR PROPERTY DAMAGE IN THE CENTRAL PACIFIC 
DIRECTLY ATTRIBUTABLE TO HURRICANE KENNETH WERE RECEIVED. AGAIN... 
SWELLS GENERATED BY THIS HURRICANE PRODUCED HIGH SURF ALONG THE EAST 
FACING SHORES OF MOST OF THE HAWAIIAN ISLANDS. MOISTURE FROM THE 
REMNANTS OF KENNETH WAS ALSO SPREADING ACROSS THE HAWAIIAN ISLANDS 
AS OF THE TIME OF THE ISSUANCE OF THIS SUMMARY.
