DISCUSSION AND OUTLOOK
----------------------
At 1100 AM HST (2100 UTC), the center of Hurricane Nolo was located 
near latitude 16.7 North, longitude 156.0 West. Nolo is moving 
toward the west near 5 mph (7 km/h) and is expected to accelerate 
westward through the weekend. Then, a turn toward the northwest and 
north-northwest is forecast on Monday and Tuesday. On the forecast 
track, the center of Nolo will remain well south and southwest of 
the main Hawaiian Islands.
 
Maximum sustained winds are near 90 mph (150 km/h) with higher 
gusts. Nolo is predicted to strengthen into a major hurricane on 
Sunday and peak in intensity by early Monday. Thereafter, steady 
weakening is expected.
 
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 150 miles
(240 km).
 
The minimum central pressure based on aircraft data is 977 mb (28.85 
inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Nolo can be found in the Tropical Cyclone
Discussion under AWIPS header HFOTCDCP2 and WMO header WTPA42 PHFO.
 
WIND: Tropical storm conditions are occurring on portions of the Big
Island and are possible in Maui County in areas of steep terrain.
Strong and gusty winds are possible for all of the Hawaiian Islands
through the weekend.
 
RAINFALL: For the eastern and southern portions of the Big Island,
Nolo will produce additional rainfall totals 3 to 6 inches, bringing
storm totals to 10 to 20 inches with isolated maximum amounts of 25
inches. This rainfall could produce significant, life-threatening
flooding and mudslides, especially in areas of steep terrain.
 
For the western portions of the Big Island, rainfall totals of 1 to
2 inches are expected. For eastern Maui, additional rainfall totals
of 1 to 2 inches are expected, bringing storm totals to 4 to 8
inches. Life-threatening flooding and mudslides are possible,
especially in areas of high terrain.
 
Across the remainder of the Hawaiian Islands, maximum storm total
rainfall amounts of 1 to 3 inches are expected.
 
For a complete depiction of forecast rainfall associated with Nolo,
please see the National Weather Service Storm Total Rainfall Graphic
available at hurricanes.gov/graphics_cp2.shtml?rainqpf
 
STORM SURGE: The threat of significant storm surge has diminished,
yet water levels along the coast will remain elevated through
upcoming tide cycles due to persistent, dangerous wave action.
 
SURF: Swells generated by Nolo are affecting exposed east- and
south-facing shores of the Big Island and are expected to spread
westward and build through the weekend. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
