000 ABNT20 KNHC 051122 TWOAT 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. $$ Forecaster Kelly

Hurricane Kirk Forecast Discussion Number 24
2024-10-05 10:40:20| National Hurricane Center (Atlantic)
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.
