DISCUSSION AND OUTLOOK
----------------------
At 500 PM HST (0300 UTC), the center of Tropical Storm Lala was
located near latitude 16.2 North, longitude 147.5 West. Lala is
moving toward the west-northwest near 12 mph (19 km/h). A faster
west-northwestward motion is expected during the next several days.
On the forecast track, Lala is forecast to be near the Big Island on 
Saturday, and pass south of the remainder of the islands later in 
the weekend.
 
Maximum sustained winds have increased to near 60 mph (95 km/h) 
with higher gusts. Steady strengthening is forecast, and Lala is 
expected to become a hurricane as it approaches the Big Island.
 
Tropical-storm-force winds extend outward up to 275 miles (445 km)
from the center.

The estimated minimum central pressure is 997 mb (29.44 inches) 
based on NOAA and Air Force Hurricane Hunter data.
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Lala can be found in the Tropical
Cyclone Discussion under AWIPS header HFOTCPCP2 and WMO header
WTPA42 PHFO.
 
WIND: Hurricane conditions are expected on the Big Island of Hawaii
by early Saturday, with tropical storm conditions possible in Maui 
County by late Saturday.  Wind speeds atop and on the windward 
sides of slopes and mountains 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: Tropical Storm Lala is expected to produce rainfall totals
of 8 to 12 inches across Maui and the Big Island with maximum totals
of 25 inches possible across the Big Island. Rainfall totals of 4
to 6 inches with maximum amounts of 8 inches across the remainder of
the island chain. This rainfall may produce life-threatening
flooding and mudslides, especially in areas of steep terrain.
 
For a complete depiction of forecast rainfall associated with
Lala, please see the National Weather Service Storm Total Rainfall
Graphic available at hurricanes.gov/graphics_cp2.shtml?rainqpf
 
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 are expected to reach the
east-facing shores of the state on Friday, spreading westward
and building through the weekend. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
