DISCUSSION AND OUTLOOK

———————-

At 200 AM HST (1200 UTC), the center of Hurricane Lane was located

near latitude 14.9 North, longitude 155.0 West. Lane is moving

toward the west-northwest near 9 mph (15 km/h) and this motion is

expected to continue tonight. A turn toward the northwest is

expected later today, followed by a turn to the north-northwest on

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 160 mph (260 km/h) with higher

gusts.  Lane is a category 5 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 estimated minimum central pressure is 935 mb (27.61 inches).

HAZARDS AFFECTING LAND

———————-

WIND: Tropical storm conditions are expected within the

Hurricane Warning area beginning late tonight into

early Thursday morning, with hurricane conditions expected

somewhere within the warning area on Thursday. Tropical storm

conditions are possible within the Hurricane Watch area beginning

Thursday into Thursday night, with hurricane conditions possible

late Thursday night into Friday.

RAINFALL: Excessive rainfall associated with Lane is expected

to affect portions of the Hawaiian Islands from late today

into the weekend, leading to flash flooding and landslides. Lane is

expected to produce total rain accumulations of 10 to 15 inches with

isolated amounts greater than 20 inches over the Hawaiian Islands.

SURF: Large swells generated by Lane will impact the Hawaiian

Islands, beginning this morning on the Big Island, spreading

across the remainder of the island chain on today. These

swells will produce large and potentially damaging surf along

exposed west, south and east facing shorelines.
