DISCUSSION AND OUTLOOK
----------------------
At 1100 PM HST (0900 UTC), the center of Tropical Depression Olivia
was located near latitude 20.0 North, longitude 160.6 West. The
depression is moving toward the west-southwest near 18 mph (30
km/h), and this general motion is expected to continue through
early Thursday with a slight decrease in forward speed, followed by
a turn toward the west late Thursday. Olivia, or its remnant low,
is forecast to turn toward the west-northwest on Friday.
 
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Little change in strength is forecast through Thursday evening.
Olivia is expected to become a post-tropical remnant low late
Thursday night or Friday.
 
The estimated minimum central pressure is 1008 mb (29.77 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
RAINFALL: Areas of heavy rainfall will likely persist through
Thursday night. Moisture associated with Olivia is expected to
produce total rainfall accumulations of 5 to 10 inches in some
areas, with isolated amounts of up to 15 inches, especially over
higher terrain. This rainfall may produce life-threatening flash
flooding. Nine inches of rain have already fallen over parts of
Maui.
 
SURF: Large swells generated by Olivia will impact parts of the
main Hawaiian Islands tonight. This will result in dangerous
surf along east facing shores.
