DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the center of Hurricane Kirk was located
near latitude 20.0 North, longitude 45.0 West. Kirk is moving
toward the northwest near 10 mph (17 km/h), and this general motion
is expected to continue through early Friday. A turn toward the
north and north-northeast at a faster forward speed is forecast
over the weekend.
Maximum sustained winds are near 120 mph (195 km/h) with higher
gusts. Kirk is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some strengthening is forecast during the
next day or so.
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 185 miles
(295 km).
The estimated minimum central pressure is 955 mb (28.20 inches).
HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Kirk are spreading westward and are
expected to reach portions of the Leeward Islands on Friday,
Bermuda and the Greater Antilles on Saturday, and the east coast
of the United States and the Bahamas on Sunday. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

Hurricane Kirk Discussion Number 16
NWS National Hurricane Center Miami FL AL122024
500 AM AST Thu Oct 03 2024
After going through a period of rapid intensification, Kirk appears
to have stopped intensifying, at least temporarily, and there are
signs in satellite imagery that a dry slot has wrapped into the
circulation. Subjective final-T numbers have decreased slightly
from TAFB and SAB, and the initial intensity is set at 105 kt, near
the CI numbers.
Kirk continues to move northwestward (315/9 kt), which should
continue for the next 36 hours while the hurricane moves along the
southwestern periphery of the subtropical high. After 36 hours,
Kirk is forecast to recurve between the high and a deep-layer trough
over the western/central Atlantic, eventually moving northeastward
by late Sunday or Monday. There is lower-than-normal spread among
the track guidance, including the global model ensembles, and
overall the new NHC track prediction is not changed much from the
previous advisory.
The hurricane is expected to move through a moist, low-shear
environment for the next 36 hours or so, with sea surface
temperatures actually warming by a degree or two up to 30 deg
Celsius. If Kirk can avoid further intrusions of dry air into the
eye, then the environment should be able to support strengthening to
category 4 strength. The NHC intensity forecast is near the top end
of the guidance during the short term. After 36 hours, increasing
deep-layer shear is likely to induce a gradual weakening trend, but
interaction with a baroclinic energy source should help the storm to
maintain hurricane-force winds through the end of the forecast
period. Based on thickness fields from the global models, Kirk is
now forecast to be extratropical by day 5.
Kirk is expected to grow in size and send out ocean swells across
the central and western Atlantic. These swells will likely increase
the risk of dangerous surf and rip currents along the Leeward
Islands by Friday, Bermuda and the Greater Antilles by Saturday, and
the U.S. East Coast and the Bahamas by Sunday.
