HAWAIIAN ISLANDS SYNOPTIC DISCUSSION AND GUIDANCE
NATIONAL WEATHER SERVICE HONOLULU HI
10 AM HST FRI FEB 9 2001

SUMMARY...A WET WEEKEND IN STORE FOR THE WESTERN END OF THE STATE...
KAUAI IN PARTICULAR...WITH A STRONG CHANCE FOR HEAVY SHOWERS AND
THUNDERSTORMS AND POSSIBLE FLASH FLOODING. THE OTHER ISLANDS WILL
SEE CONSIDERABLE CLOUDINESS WITH SHOWERS AT TIMES...SOME MAY BE
HEAVY WITH CHANCE OF THUNDERSTORMS.

DISCUSSION...CONVERGENT SURFACE AIR FLOW BENEATH DIVERGENT AIR FLOW
ALOFT WITH THE ADDED SPARK OF THE BIG ISLAND CONVERGENCE PLUME
TURNING NORTHWESTWARD JUST TO THE SOUTH OF KAUAI HAS PROMPTED A
FLASH FLOOD WATCH FOR THAT ISLAND. HEAVY SHOWERS AND THUNDERSTORMS
HAVE BEEN OCCURRING OVER KAUAI THIS MORNING...WITH 7.25 INCHES OF
RAINFALL REPORTED AT THE HANALEI GAGE OVER THE PAST 24 HOURS...WITH
NEARLY 5.5 INCHES OF THAT IN THE LAST 6 HOURS. WAINIHA CONTINUES TO
SEE HEAVY SHOWERS THIS MORNING...AND BARKING SANDS ALSO REPORTING A
THUNDERSTORM CONTINUING FOR THE PAST SEVERAL HOURS. THIS HAS
PROMPTED THE ISSUANCE AND CONTINUATION OF AN URBAN AND SMALL STREAM
FLOOD ADVISORY FOR THE ENTIRE ISLAND OF KAUAI.

FORECAST CHARTS ARE NOT INDICATING MUCH CHANGE IN THIS SITUATION
RIGHT THROUGH THE WEEKEND...AND THIS COULD SPELL TROUBLE FOR THE
WESTERN ISLANDS OF KAUAI AND OAHU. FOR THE REST OF THE STATE EXPECT
SKIES TO REMAIN CLOUDY THROUGH THE WEEKEND...WITH SOME SHOWERS AT
TIMES. SOME OF THESE SHOWERS COULD BE HEAVY...ESPECIALLY ON THE BIG
ISLAND DUE TO LOCAL EFFECTS. WILL WATCH THE CONVERGENT PLUME WEST OF
THE BIG ISLAND...ESPECIALLY WITH THE AVIATION MODEL TURNING WINDS
MORE SOUTHERLY WITH TIME. THIS COULD BRING SOME OF THE HEAVYIER
SHOWERS AND THUNDERSTORMS OVER TO OAHU AS WELL AS KAUAI.
