DISCUSSION AND OUTLOOK
----------------------
At 1100 PM HST (0900 UTC), the center of Hurricane Lala was located
near latitude 19.6 North, longitude 157.0 West. Lala is moving
toward the northwest near 15 mph (24 km/h), and this general
motion is expected to continue overnight. A gradual westward turn
with an increase in forward speed is expected on Sunday, as the
core of the storm remains south of the smaller main Hawaiian Islands
and the easternmost Northwestern Hawaiian Islands through the early
part of next week.
 
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. This intensity of Lala is forecast to remain steady
for a few more hours, followed by a gradual weakening trend on 
Sunday as Lala passes south of the smaller main Hawaiian Islands. 
Some restrengthening is possible next week.
 
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 175 miles
(280 km).
 
The estimated minimum central pressure is 988 mb (29.18 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Lala can be found in the Tropical Cyclone
Discussion under AWIPS header HFOTCDCP2 and WMO header WTPA42 PHFO.
 
WIND: Damaging winds will persist across portions of the Big Island 
of Hawaii overnight, with the strongest winds expected in areas of 
higher terrain. Tropical storm conditions will continue to spread 
westward from Maui County to Oahu into early Sunday, then to Kauai 
County through the day Sunday. Wind speeds atop mountains and on the 
windward and leeward slopes are often up to 30 percent stronger than 
the near-surface winds indicated in this advisory, and in some 
elevated locations could be even greater.
 
RAINFALL: Lala is expected to produce additional rainfall of 4 to 8
inches across the Big Island and windward Maui, with maximum storm
total of 30 to 35 inches over the windward Big Island. Across the
remainder of the island chain total rainfall of 4 to 6 inches, with
maximum amounts of 8 inches, is expected. This rainfall will produce
life-threatening flooding and mudslides, especially in areas of
steep terrain.

For a list of rainfall observations and wind reports associated with
Lala, see the companion storm summary at WBCSCCNS2 with the WMO
header ACUS42 KWBC or at the following link:
www.wpc.ncep.noaa.gov/discussions/nfdscc2.html.
 
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
 
Hawaii...1 to 3 ft
 
The deepest water will occur along the immediate coast, where the
surge will be accompanied by large and dangerous waves.
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.
 
For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_cp2.shtml?peakSurge.
 
SURF: Swells generated by Lala will continue to build westward
across the exposed windward waters through Sunday. Swells will also
build over the exposed leeward waters as Lala passes south of the
islands. These swells are likely to cause life-threatening surf and
rip current conditions. Please consult products from your local
weather office.
