DISCUSSION AND OUTLOOK
----------------------
At 1100 PM HST (0900 UTC), the center of Hurricane Lane was located
near latitude 18.2 North, longitude 158.0 West. Lane is moving
toward the north near 6 mph (9 km/h), and this general motion is
expected to continue through Friday. A turn toward the west is
anticipated Saturday, with an increase in forward speed. On the
latest forecast track, the center of Lane will move over, or
dangerously close to portions of the main Hawaiian islands late
Friday and Friday night.
 
Maximum sustained winds are near 120 mph (195 km/h) with higher
gusts. Lane remains a powerful category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Some weakening is forecast
from Friday through late Saturday, but Lane is expected to remain a
hurricane as it approaches the islands.
 
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 125 miles
(205 km).
 
The estimated minimum central pressure is 956 mb (28.23 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are already occurring on the Big
Island, Maui County and Oahu. These conditions will likely
persist through early Friday morning. Hurricane conditions are
expected over some areas of Maui County and Oahu starting Friday
and continuing through Friday night. Tropical storm or hurricane
conditions are possible on Kauai starting late Friday or Friday
night.
 
RAINFALL: Rain bands will continue to overspread the Hawaiian
Islands well ahead of Lane. Excessive rainfall associated with this
slow moving hurricane will continue to impact the Hawaiian Islands
into the weekend, leading to significant and life-threatening flash
flooding and landslides. Lane is expected to produce total rain
accumulations of 10 to 20 inches, with localized amounts of 30 to 40
inches possible over portions of the Hawaiian Islands. Over two feet
of rain has already fallen at a few locations on the windward side
of the Big Island.
 
SURF: Very large swells generated by the slow moving hurricane will
severely impact the Hawaiian Islands over the next couple of days.
These swells will produce extremely large and damaging surf along
exposed west and south facing shorelines. A prolonged period of high
surf will likely lead to significant coastal erosion.
 
STORM SURGE: The combination of a dangerous storm surge and large
breaking waves will raise water levels by as much as 2 to 4 feet
above normal tide levels along south and west facing shores near
the center of Lane. The surge will be accompanied by large and
destructive waves.
