...THIS IS THE LAST ADVISORY...
 
 
SUMMARY OF 500 AM HST...1500 UTC...INFORMATION
----------------------------------------------
LOCATION...20.3N 144.0W
ABOUT 720 MI...1160 KM E OF HILO HAWAII
ABOUT 900 MI...1450 KM E OF HONOLULU HAWAII
MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H
PRESENT MOVEMENT...W OR 280 DEGREES AT 17 MPH...28 KM/H
MINIMUM CENTRAL PRESSURE...1006 MB...29.71 INCHES
 
 
WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.
 
Although Linda has become post-tropical, remnants of the system are
expected to impact portions of the main Hawaiian Islands Sunday and 
Monday. Interests in Hawaii should monitor the progress of the 
remnant low.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 500 AM HST (1500 UTC), the center of Post-Tropical Cyclone Linda
was located near latitude 20.3 North, longitude 144.0 West. The
post-tropical cyclone is moving toward the west near 17 mph (28
km/h), and this general motion is expected to continue for the next 
few days, with some slowing in forward speed tonight and Saturday.
 
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Little change in strength is forecast during the next 48 hours, with 
weakening expected thereafter. Dissipation is expected early next 
week.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center.
 
The estimated minimum central pressure is 1006 mb (29.71 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Linda will affect east facing shores
of the main Hawaiian Islands over the next couple of days. Please
consult products from the National Weather Service's Honolulu
Forecast Office.
 
 
NEXT ADVISORY
-------------
This is the last public advisory issued by the Central Pacific
Hurricane Center on Linda. Future information on this system can be 
found in forecasts issued by the National Weather Service in 
Honolulu, on the web at http://weather.gov/hfo.

Post-Tropical Cyclone LINDA Forecast Discussion

Post-Tropical Cyclone Linda Discussion Number  42
NWS Central Pacific Hurricane Center Honolulu HI   EP122021

Linda's time as a tropical cyclone has come to an end. Infrared and 
VIIRS day-night satellite imagery depict an elongating low cloud 
swirl, and deep convection has been absent over the center for 
nearly 24 hours, thus Linda is deemed to be post-tropical. The 
initial intensity estimate of 35 kt for this advisory remains 
heavily influenced by a recent scatterometer pass that indicated 
winds to 40 kt north of the center.

The initial motion estimate is 280/15 kt, with Linda being steered 
by a persistent low- to mid-level ridge to the north. Tightly-
clustered track guidance indicates that the ridge will continue to 
drive the post-tropical remains of Linda toward the west, with a 
slight reduction in forward speed tonight and Saturday. The guidance 
has trended southward over the last couple of days, and the official 
forecast indicates that remnants of Linda will impact portions of 
the main Hawaiian Islands Sunday and Monday, in line with the 
corrected consensus guidance HCCA, and the GEFS mean. 

Compared to the recent rapid weakening, a relatively slow rate of 
decay of the wind field is expected over the next couple of days. 
As the system gradually spins down, gale force winds north of the 
center will be slow to diminish, due to the gradient between the 
high to the north and the remnant low. Some sporadic deep convection 
may also occur, but the combined effects of dry air in the mid- and 
upper-levels and increasing vertical wind shear will prevent 
regeneration into a tropical cyclone, and lead to system dissipation 
by day 4. This is supported by the reliable global models, as well 
as the intensity consensus IVCN.

This is the last advisory issued by the Central Pacific Hurricane 
Center on Linda. Future information on this system can be found in 
forecasts issued by the National Weather Service in Honolulu, on 
the web at http://weather.gov/hfo.
