HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are still expected in and near
rain bands that will affect Oahu, Maui County, and the Big Island
tonight into Saturday. Tropical storm conditions are possible on
Kauai starting Saturday.
 
RAINFALL: Excessive rainfall remains possible into the weekend,
which could lead to additional 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 Lane will impact the Hawaiian
Islands into the weekend. These swells will produce high surf along
exposed south and east shorelines through Saturday.
