48 hours.
 
Interests elsewhere in the main Hawaiian Islands, and in the

DISCUSSION AND OUTLOOK
----------------------
At 1100 PM HST (0900 UTC), the center of Tropical Storm Lala was 
located near latitude 16.7 North, longitude 148.9 West. Lala is 
moving toward the west-northwest near 10 mph (17 km/h). A 
west-northwestward motion is expected during the next several days, 
with some slowing in forward speed as Lala approaches the Big Island 
on Saturday, followed by an increase in forward speed later in the 
weekend.
 
Maximum sustained winds are 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 minimum central pressure estimated from Air Force Reserve 
Hurricane Hunter aircraft data is 997 mb (29.44 inches).
 
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.
