DISCUSSION AND OUTLOOK
----------------------
At 200 PM HST (0000 UTC), the eye of Hurricane Lala was located
near latitude 18.3 North, longitude 155.7 West. Lala is moving
toward the northwest near 8 mph (13 km/h). Some erratic motion 
remains possible into tonight while Lala interacts with the Big
Island of Hawaii. After passing the Big Island, Lala is expected to 
turn westward on Sunday with an increase in forward speed, 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. Intensity is forecast to remain steady over the next several 
hours as Lala remains near South Point of the Big Island. 
Thereafter, significant weakening is expected tonight into Sunday as 
Lala passes south of the smaller main Hawaiian Islands. Some 
restrengthening is possible early 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: Hurricane conditions will persist on the Big Island of Hawaii 
into tonight, with the strongest winds expected in areas of higher 
terrain. Tropical storm conditions will continue to spread westward 
across portions of the smaller islands from Maui County and Oahu 
later today through tonight, then to Kauai County on 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 rainfall totals of 10 to 20
inches across the Big Island, with maximum totals of 25 inches
possible. Rainfall of 8 to 12 inches is expected across eastern
Maui, with totals of 4 to 6 inches, and maximum amounts of 8 inches,
across western Maui and the remainder of the island chain. 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 through the
weekend. Swells will also build along exposed southern shores 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.
