Small Craft Advisory 31, NWS Honolulu, HI

Area Forecast Discussion...UPDATED
National Weather Service Honolulu HI
1232 AM HST Sat Aug 25 2018

.SYNOPSIS...
Tropical Storm Lane is moving toward the north-northwest near 3
mph, and this general motion is expected to continue through
Saturday morning. This will likely be followed by a turn toward
the west with an increase in forward speed starting Saturday
afternoon. Although Lane will continue to weaken along this track,
the threat for flash flooding remains in the forecast through the
weekend. The wet pattern will likely hold through the first half
of next week across the western end of the state. A drying trend
will gradually fill in from east to west through midweek.

.DISCUSSION...
The 11 pm HST advisory from the Central Pacific Hurricane Center
(CPHC) has Tropical Storm Lane positioned around 135 miles south-
southwest of Honolulu tracking toward the north-northwest around 3
mph. Maximum sustained winds associated with Lane remain at 65
mph near the center. Lane is forecast to gradually make a turn
toward the west Saturday afternoon, passing south of Kauai.

Although Lane will continue to weaken along the forecast track,
the threat for flash flooding will continue over the weekend. The
latest radar imagery showed the heaviest rainfall continuing to
focus over Maui County and the Big Island this morning. No changes
are anticipated through daybreak (1-3 inch per hour rates in the
heaviest activity). Later today through Sunday, the rainfall and
flash flooding threat will slowly shift westward toward Oahu and
Kauai. As a result, the flash flood warning will likely be
extended through Saturday night in later forecasts this morning.

For the extended period (next week), a trailing deep tropical
moisture axis is forecast to hold over the western end of the state
through the first half of the week as Lane turns northward well west
of Kauai. This will keep the threat for heavy rainfall and flooding
in place, mainly for Kauai and Oahu. A gradual drying trend is
anticipated from east to west through midweek.

For additional details with regard to impacts for each island
associated with Lane, refer to the latest local statements issued
with each advisory package (next issuance 11 pm - midnight;
TCV/HLS).

.AVIATION...
AIRMET Sierra for mountain obscuration is in effect for NE
sections of the Big Island, Maui, Molokai, Oahu and Kauai. These
conditions are likely to continue through Saturday. Heavy showers
and isolated thunderstorms over NE sections of the Big Island and
Maui and over waters within 40nm NE of those islands will produce
isolated IFR ceilings and visibilities.

AIRMET Tango is in effect for moderate low level turbulence in
areas south through west of the mountains of all islands and for
strong surface winds from the Big Island to Molokai.

Light rime icing is expected in layered clouds above FL200.

&&

.MARINE...
Tropical Storm Lane is forecast to make a turn toward the west
and pass south of Kauai late Saturday and Saturday night. Heavy
precipitation associated with Lane will continue to fall over
the coastal waters, through the weekend.

Surf will remain elevated along exposed shores through Saturday
as Lane begins to move off to the west. Heights along the south
shores will likely lower into average range no later than Sunday.
East shores will remain elevated beyond Saturday due to expected
strong onshore winds filling in as Lane exits.

See the Coastal Hazard Message (HFOCFWHFO) for surf advisories and
the Marine Weather Message (HFOMWWHFO) for marine warnings over
the coastal waters.
