south of the Big Island on Saturday, and pass south of the smaller 
islands during the remainder of the weekend.
 
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. 
 Steady strengthening is forecast, and Lala could be near hurricane 
strength as it approaches the Big Island.

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 possible in the Big Island of Hawaii
by early Saturday.  Wind speeds atop and on the windward sides of
hills 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 5 to 10 inches across much of the Island chain, with maximum
totals of 20 inches possible. This rainfall may produce
life-threatening flooding and mudslides, especially in areas of
steep terrain.
 
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.
