SUMMARY OF INFORMATION
-----------------------------------
LOCATION...NEAR    ...
MAXIMUM SUSTAINED WINDS...MPH...KM/H
MINIMUM CENTRAL PRESSURE...MB
 
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
-----------------------------------
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
