DISCUSSION AND OUTLOOK
----------------------
At 1100 AM HST (2100 UTC), the center of Hurricane Lala was located
near latitude 18.2 North, longitude 155.2 West. Lala is moving
toward the northwest near 8 mph (13 km/h). Some erratic motion is
likely later today and 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, with the
core of the storm staying south of remainder of the 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.  Some slight strengthening is possible during the next few
hours, but significant weakening is likely tonight after Lala
interacts with the Big Island of Hawaii. 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: Tropical storm conditions, including gusts to hurricane force,
are occurring on the Big Island of Hawaii, especially in areas of
higher terrain. Winds will continue to increase on the Big Island
during the next few hours. Tropical storm conditions are spreading
westward across portions of Maui County and Kauai, and are expected
to reach 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.
