DISCUSSION AND OUTLOOK
----------------------
At 200 AM HST (1200 UTC), the center of Hurricane Olivia was located
near latitude 21.7 North, longitude 147.6 West. Olivia is moving
toward the west near 10 mph (16 km/h). This general motion is
expected to continue early today, followed by a turn toward the
west-southwest starting later today. This west-southwest motion is
expected to continue through Tuesday evening. On this forecast
track, tropical storm conditions are possible over some parts of
Hawaii starting Tuesday.
 
Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Little change in strength is forecast today, with gradual
weakening possible starting some time on Tuesday.
 
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 120
miles (195 km).
 
The estimated minimum central pressure is 980 mb (28.94 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
 
WIND: Tropical storm conditions are possible within the watch area
starting Tuesday.
 
RAINFALL: Olivia is expected to produce total rainfall accumulations
of 10 to 15 inches. Isolated maximum amounts of 20 inches are
possible, especially over windward sides of Maui and the Big Island.
This rainfall may produce life-threatening flash flooding.
 
SURF: Large swells generated by Olivia will spread from east to
west across the Hawaiian Islands early this week. This will cause
surf to build along exposed east facing shorelines as Olivia
approaches. This surf may become damaging across parts of the state.
