Hurricane Lowell Discussion Number  33

There has not been any significant changes with Lowell over the past 
several hours. The major hurricane is maintaining an eye in 
satellite imagery with an intense ring of deep convection around the 
center. The convective pattern is a little asymmetric with the 
strongest thunderstorms currently occurring south of the center. The 
latest satellite intensity estimates range from 102 to 120 kt, and 
based on that data, the initial wind speed is held at 110 kt. The 
Air Force Hurricane Hunters are scheduled to investigate Lowell 
later today, and the information they collect will be very helpful 
in assessing the cyclone's intensity and structure.
 
Lowell has been losing some latitude this morning, with the initial 
motion estimated to be just south of due west, or 265/7 kt. A 
general westward motion is expected through Saturday as Lowell 
remains steered by the flow on the southeastern side of a mid-level 
ridge. On Sunday, the steering pattern is expected to change when a 
mid- to upper-level low moves southwestward north of the Hawaiian 
Islands, eroding the southern portion of the ridge. This pattern 
change should cause a sharp turn to the north or north-northeast 
with a gradual increase in forward speed, bringing the system close 
to the westernmost Hawaiian Islands on Monday and Monday night. It 
should be noted that predicting where and how sharply Lowell turns 
is challenging as it will depend on the location and amplitude of 
the mid- to upper-level low relative to the hurricane's location. 
Although the models agree on the overall setup and all show Lowell 
turning, there is a notable amount of spread on how close the core 
of Lowell gets to Kauai County. This forecast is quite similar to 
the previous one and near a blend of the best-performing aids so far 
this season, the Google DeepMind ensemble mean and consensus aids 
HCCA and TVCN.
 
The atmospheric and oceanic conditions are expected to be conducive 
for strengthening over the next two to three days, and it seems 
likely that Lowell will restrengthen back to a category 4 hurricane 
during that period. Beyond that time, a notable increase in 
southwesterly vertical wind shear and cooler waters should cause 
steady weakening. However, Lowell is still forecast to be near major 
hurricane strength when makes its closest approach to the Hawaiian 
Islands. The NHC intensity forecast lies near the high end of the 
model guidance, in best agreement with HCCA.
 
 
KEY MESSAGES:
 
1. Lowell could be near major hurricane strength when it moves 
close to the western Hawaiian Islands late Monday and Monday night. 
Regardless of the hurricane's exact track and intensity, there is a 
risk of storm surge, wind, and rainfall impacts for portions of 
Hawaii, particularly Kauai County, early next week.

2. Interests in Hawaii should continue to closely monitor the 
progress of Lowell through the upcoming Labor Day weekend, listen to 
the advice of local officials, and ensure they have their hurricane 
plan and supply kit in place. Watches are likely to be issued for a 
portion of the state on Saturday.

3. Swells from Lowell are likely to cause life-threatening surf 
and rip current conditions in portions of the Hawaiian Islands 
during the next several days.  These swells are likely to increase 
early next week.
