NATIONAL WEATHER SERVICE HONOLULU HI
5 PM HST TUE JAN 29 2002

SUMMARY...A LOW PRESSURE SYSTEM TO THE WEST OF HAWAII IS BRINGING
MOIST AND UNSTABLE AIR NORTHWARD ACROSS THE ISLANDS. THE LOW WILL
REMAIN TO THE WEST AND MOVE AWAY WESTWARD TOMORROW TO DIMINISH THE
RAIN AND SHOWERS BY THEN. MORE NORMAL TRADE WIND WEATHER WILL RETURN
LATER THIS WEEK.

DISCUSSION...THE LOW PRESSURE SYSTEM WEST OF KAUAI IS DRIFTING WEST
VERY SLOWLY...LEAVING THE STATE IN ITS VERY WET AND INCREASINGLY
WINDY EASTERN FLANK. RAINFALL IS HEAVIEST AT THIS TIME ALONG THE
BIG ISLAND KAU AND PUNA AND HILO DISTRICTS WHERE THE SOUTHEAST AND
EAST WINDS MOVE INLAND OVER THE SLOPING TERRAIN. THE WINDS WILL
BECOME MORE TRADE LIKE WITH TIME...THAT IS...THEY WILL BECOME MORE
EASTERLY FROM THE PRESENT SOUTHEAST DIRECTION. THIS WILL MOVE THE
RAINFALL TO THE MORE EASTWARD FACING SLOPES SUCH AS THE HAMAKUA
COAST AND EAST MAUI SLOPES OF HALEAKALA. STRONG EASTERLY WINDS NEAR
30 MPH ARE PRESENT JUST EAST OF THE STATE. THESE WINDS WILL LIKELY
OVERSPREAD THE ISLANDS DURING THE NIGHT AND TOMORROW AS THE KONA LOW
OUT TO THE WEST MOVES AWAY WESTWARD AND WEAKENS AND THE HIGH TO THE
NORTH SPREADS ITS INFLUENCE INTO OUR AREA. THE EASTERLY SWELL WILL
ALSO INCREASE AS THESE WINDS ARRIVE.  ROSENDAL
