Kirk is moving toward the north near 16 mph (26 km/h) and this motion is expected to continue through tonight. A faster northeastward motion is expected on Sunday and Monday. 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. Weakening is forecast through early next week, but Kirk will remain a large hurricane for the next couple of days. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The estimated minimum central pressure is 949 mb (28.03 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Kirk are affecting the Leeward Islands, Bermuda, and the Greater Antilles. These swells are expected to spread westward to the east coast of the United States, Atlantic Canada, and the Bahamas Saturday night and Sunday, and to the Azores on Monday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Issued at 1100 AM AST Sat Oct 05 2024 000 WTNT43 KNHC 051450 TCDAT3 Hurricane Leslie Discussion Number 13 NWS National Hurricane Center Miami FL AL132024 1100 AM AST Sat Oct 05 2024 Deep convection continues to burst over the center of Leslie this morning. Some of the latest satellite images depict a little bit of shear starting to impact the system, with a sharper convective edge on the western side. Subjective and objective satellite intensity estimates range from 65 to 75 kt. Using a blend of these estimates, the initial intensity is held at 70 kt for this advisory. Leslie continues to move slowly west-northwestward (295/6 kt), steered by a mid-level subtropical ridge over the eastern Atlantic. The ridge will continue to steer Leslie the next several days with a turn more northwestward, with an increase in forward speed by the middle of the forecast period. The NHC track forecast is very close to the previous, and lies near the simple and corrected consensus aids. The intensity forecast continues to trend downward with Leslie. The system has about 12-24 hours left within a favorable environment where some slight additional strengthening may occur. By Sunday, increased shear, drier mid-level, and the track taking Leslie over Kirk's cold wake, this could cause some weakening after 24 hours. There is better agreement with the weakening trend, however they differ on how significantly and how quickly weakening will occur. Therefore, downward adjustments were made to the NHC intensity forecast and now has Leslie weakening below hurricane strength beyond 48 h. If trends continue further downward adjustments may be required in future advisories.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Sat Oct 5 2024

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Kirk, located over the central subtropical Atlantic Ocean, and on
Hurricane Leslie, located over the eastern tropical Atlantic
Ocean.

Gulf of Mexico (AL92):
Showers and thunderstorms associated with a broad area of low
pressure located over the southwestern Gulf of Mexico are gradually
becoming better organized. Development of this system is expected,
and a tropical depression or storm is likely to form later today or
on Sunday while it moves slowly eastward over the southwestern Gulf
of Mexico. By early next week, the system is forecast to move
faster eastward or northeastward across the central and eastern Gulf
of Mexico where additional strengthening is likely. Interests on
the Yucatan peninsula of Mexico, the Florida Peninsula, the Florida
Keys, and the northwestern Bahamas should monitor the progress of
this system. Regardless of development, locally heavy rains could
occur over portions of Mexico during the next day or two, and over
much of Florida late this weekend through the middle of next week.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...90 percent.

Far Eastern Tropical Atlantic:
A tropical wave is expected to move off the west coast of Africa on
Monday or Tuesday. Some development of this system is possible
thereafter while it moves westward or west-northwestward across the
eastern tropical Atlantic. The system is expected to move near or
over the Cabo Verde Islands on Wednesday and Thursday, and interests
there should monitor its progress.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

Issued at 500 AM AST Sat Oct 05 2024 000 WTNT42 KNHC 050840 TCDAT2 Hurricane Kirk Discussion Number 24 NWS National Hurricane Center Miami FL AL122024 500 AM AST Sat Oct 05 2024 The eye of Kirk has become ragged and cloud filled during the past several hours. The satellite presentation suggests that southwesterly shear and intrusions of dry air are negatively affecting the hurricane, as a pronounced dry slot is noted on the western side of Kirk. As a result of these structural changes, the satellite intensity estimates have decreased overnight. Based on a blend of the latest subjective Dvorak Current Intensity estimates from TAFB and SAB with recent UW-CIMSS objective estimates, the initial intensity is lowered to 110 kt. Kirk continues to turn more northward (340/11 kt) within the flow between a shortwave trough over the west-central Atlantic and a subtropical ridge to the east of the hurricane. The track models agree that Kirk should keep recurving to the northeast and east-northeast through early next week while accelerating within strong mid-latitude flow. The NHC forecast track shows the center of Kirk passing to the north of the Azores on Monday as an extratropical cyclone, and then moving across the northeastern Atlantic and over western Europe by the middle of next week. No significant changes were made to the updated NHC prediction. The environmental conditions are expected to become increasingly hostile over the coming days, with a marked increase in shear and a drier environment surrounding the hurricane while it moves over progressively cooler waters. Therefore, steady weakening is forecast through early next week. Kirk should lose tropical characteristics and transition to a strong extratropical cyclone between 60-72 h, which is supported by the global model fields and simulated satellite imagery. The updated NHC intensity forecast shows a slightly faster rate of weakening, close to or slightly above the latest HCCA aid. However, note that the wind field of the cyclone is forecast to remain quite large through the 5-day forecast period. Large and powerful Kirk is producing ocean swells that are propagating far away from the hurricane. These large swells will likely increase the risk of dangerous surf and rip currents across the Leeward Islands, Bermuda, and the Greater Antilles beginning later today, much of the U.S. East Coast, Atlantic Canada, and the Bahamas by Sunday, and the Azores by Monday.

Interests in the Azores should monitor the progress of Kirk. DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Hurricane Kirk was located near latitude 26.2 North, longitude 50.2 West. Kirk is moving toward the north-northwest near 13 mph (20 km/h). A turn to the north is expected today, followed by a faster northeastward motion on Sunday and Monday. Maximum sustained winds are near 125 mph (205 km/h) with higher gusts. Kirk is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Weakening is forecast through early next week, but Kirk will remain a large hurricane for the next couple of days. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 220 miles (350 km). The estimated minimum central pressure is 945 mb (27.91 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Kirk are affecting the Leeward Islands, Bermuda, and the Greater Antilles. These swells are expected to spread westward to the east coast of the United States, Atlantic Canada, and the Bahamas Saturday night and Sunday, and to the Azores on Monday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Issued at 500 AM AST Sat Oct 05 2024 000 WTNT43 KNHC 050837 TCDAT3 Hurricane Leslie Discussion Number 12 NWS National Hurricane Center Miami FL AL132024 500 AM AST Sat Oct 05 2024 A 0552 UTC SSMIS microwave pass showed that Leslie still has a well-defined mid-level eye, and deep convection continues to burst over the center. Dvorak estimates from TAFB and SAB are both T4.0/65 kt, while objective numbers are overall a bit higher than that. Therefore, Leslie's intensity is now estimated to be 70 kt. Leslie continues to move slowly west-northwestward (290/6 kt), with the cyclone still located along the southern periphery of the subtropical ridge. The ridge is expected to remain entrenched and strengthen over the eastern Atlantic during the next several days, which should cause Leslie to move northwestward and accelerate a bit by Tuesday and Wednesday. The NHC forecast is close to a blend of the TVCA and HCCA consensus aids, and nearly lies on top of the previous prediction. The intensity forecast is the most challenging part of this advisory. Deep-layer shear is relatively low at the moment and should remain so for the next 24 hours or so. This is the period where the NHC forecast shows additional strengthening, and is close to the statistical-dynamical models near the top end of the guidance. Increased shear, combined with Leslie potentially moving over Kirk's cold wake, could cause some weakening after 24 hours. All of the intensity models support this scenario, however they differ significantly in how much weakening will occur. The NHC forecast continues to show Leslie maintaining hurricane status through day 5, mainly following the SHIPS model. However, the IVCN and HCCA consensus aids, as well as several of the hurricane regional models, suggest that Leslie could weaken below hurricane intensity by 48 hours. Downward adjustments to the intensity forecast may be required in future advisories if this trend continues.
