The center of Lane will remain close to central Hawaiian islands
today and tonight.

HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are already occurring on the Big
Island, Maui County and Oahu. Hurricane conditions are expected over
portions of of Maui County and Oahu starting tonight. Tropical storm
conditions are possible on Kauai starting Saturday.
 
RAINFALL: Rain bands from Lane will continue to affect the main
Hawaiian Islands with excessive rainfall possible into the weekend.
These rains could lead to additional major flash flooding and
landslides. Lane is expected to produce total rain accumulations of
10 to 20 inches in some areas. Localized storm total amounts up to
40 inches are possible, mainly on the windward side of the Big
Island where over 30 inches of rain has already fallen in some
areas.
 
SURF: Large swells generated by the slow moving hurricane will
impact the Hawaiian Islands into the weekend. These swells
will produce high and possibly damaging surf along exposed south
shorelines today through Saturday. In addition, a prolonged period
of high surf may lead to significant coastal erosion.
