None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Hurricane Watch is in effect for…
*Maui County…including the islands of Maui, Lanai, Molokai and
Kahoolawe
*Hawaii County

A Hurricane Watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours before
the anticipated first occurrence of tropical-storm-force winds,
conditions that make outside preparations difficult or dangerous.

Interests elsewhere in the main Hawaiian Islands, and across the
Northwestern Hawaiian Islands, should continue to closely monitor
the progress of Hurricane Lane. Additional Tropical Storm or
Hurricane Watches will likely be issued this afternoon or tonight.

For storm information specific to your area, please monitor
products issued by the National Weather Service office in
Honolulu Hawaii.

DISCUSSION AND OUTLOOK
———————-
At 1100 AM HST (2100 UTC), the center of Hurricane Lane was located
by U.S. Air Force Reserve Hurricane Hunter aircraft near latitude
14.3 North, longitude 153.2 West. Lane is moving toward the
west-northwest near 9 mph (15 km/h) and this motion is expected to
continue through tonight. A turn toward the northwest is expected
Wednesday into Thursday. On the forecast track, the center
of Lane will move very close to or over the main Hawaiian
Islands from Thursday through Saturday.

Maximum sustained winds are near 155 mph (250 km/h) with higher
gusts. Lane is a powerful Category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Slow weakening is
forecast during the next 48 hours, but Lane is forecast to remain a
dangerous hurricane as it draws closer to the Hawaiian Islands.

Hurricane-force winds extend outward up to 40 miles (65 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km).

The minimum central pressure as recently reported by hurricane
hunter aircraft is 941 mb (27.79 inches).

HAZARDS AFFECTING LAND
———————-
WIND: Tropical storm conditions are possible within the
Hurricane Watch area beginning Wednesday night, with hurricane
conditions possible on Thursday.

RAINFALL: Excessive rainfall associated with Lane is expected
to affect portions of the Hawaiian Islands from Wednesday into the
weekend, leading to flash flooding and landslides. Lane is expected
to produce total rain accumulations of 10 to 15 inches with isolated
maximum amounts of 20 inches over the Hawaiian Islands.

SURF: Large swells generated by Lane will impact the Hawaiian
Islands, beginning tonight on the Big Island and spreading
across the remainder of the island chain Wednesday through
Thursday. These swells will produce large and potentially
damaging surf along exposed west, south and east facing
shorelines.
