DISCUSSION AND OUTLOOK
----------------------
At 200 AM HST (1200 UTC), the center of Tropical Storm Olivia was
located near latitude 20.8 North, longitude 155.0 West. Olivia is
moving toward the west-southwest near 7 mph (11 km/h). A general
motion toward the west-southwest, with a gradual increase in forward
speed, is expected this morning as the center of Olivia approaches
Maui and the Big Island. On the forecast track, Olivia will move
very close to Maui later this morning. After Olivia moves past the
islands, a somewhat faster west-southwest motion is expected to
resume and continue for the next couple of days.
 
Maximum sustained winds are near 45 mph (75 km/h) with higher
gusts. Some weakening is forecast during the next 48 hours, but
Olivia is expected to remain a tropical storm for the next day or
so.
 
Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center, mainly to the north of the center.
 
The estimated minimum central pressure is 1005 mb (29.68 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected over portions of
Maui County and the Big Island today. Tropical storm conditions are
expected to begin over Oahu later this morning. Remember that wind
gusts can be much stronger near higher terrain, and in the upper
floors of high-rise buildings. Winds can also be especially gusty
through gaps between mountains and where winds blow downslope.
 
RAINFALL: Showers will continue to increase over the main Hawaiian
Islands today. Olivia is expected to produce total rainfall
accumulations of 5 to 10 inches in some areas, with isolated maximum
amounts of 15 inches possible, especially in higher terrain. This
rainfall may produce life-threatening flash flooding. Up to three
inches of rain has already fallen over parts of Maui. 
 
SURF: Large swells generated by Olivia will impact the main Hawaiian
Islands over the next couple of days. This will result in
dangerously high and potentially damaging surf, mainly along
exposed east facing shores.
