HAZARDS AFFECTING LAND
----------------------
Key messages for Lala can be found in the Tropical Cyclone
Discussion under AWIPS header HFOTCDCP2 and WMO header WTPA42 PHFO.
 
WIND: Tropical storm conditions, especially in gusts, are ongoing 
across portions of Kauai County, with the strongest winds occurring 
in areas of higher terrain. Wind speeds atop mountains and on the 
windward and leeward slopes 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: Outer bands from Lala are expected to produce additional 
rainfall of 1 to 2 inches across windward portions of the Big Island 
and windward Maui, with maximum storm totals of 30 to 40 inches over 
the windward Big Island. Across the remainder of the island chain an 
additional 2 to 4 inches of rainfall is expected, with isolated 
additional totals around 6 inches. This rainfall may produce 
flooding and mudslides, especially in areas of steep terrain.

STORM SURGE: Water levels may remain elevated through the next tide 
cycle due to persistent large and dangerous wave activity.
 
SURF: Large waves generated by Lala will continue to impact exposed 
waters of the Hawaiian Islands through tonight, with a gradual 
downward trend expected from east to west by Monday. 
Life-threatening surf and rip current conditions will continue.
