Hawaiian Islands early next week.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Little change in strength is expected tonight, but a gradual
weakening trend is forecast to begin on Sunday.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The minimum central pressure is 999 mb (29.50 inches) based on data
from NOAA and Air Force Reserve reconnaissance aircraft.


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Moke can be found in the Tropical
Cyclone Discussion under AWIPS header HFOTCDCP3 and WMO header
WTPA43 PHFO.

WIND: Gusty winds are expected across the Hawaiian Islands late
tonight and Sunday, especially in areas of high terrain.

RAINFALL: Moke is expected to produce rainfall totals of 5 to 10
inches with maximum amounts of 15 inches across the Big Island.
Rainfall totals of 3 to 6 inches are expected on eastern Maui. These
rainfall amounts may produce life-threatening flooding and mudslides

terrain and over areas that were affected recently by Lala.

Across western Maui and the remainder of the islands, moisture drawn
northward from Moke may bring up to 1 or 2 inches of rain.
