691 ABNT20 KNHC 010532 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Tue Oct 1 2024 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Active Systems: The National Hurricane Center is issuing advisories on Tropical Storm Kirk, located over the eastern Atlantic Ocean. The National Hurricane Center has issued the last advisory on Tropical Depression Joyce, whose remnants are located over the central Atlantic Ocean. Northwestern Caribbean Sea and Gulf of Mexico: Disorganized showers and thunderstorms located over the southwestern Caribbean Sea are associated with a trough of low pressure. Environmental conditions could support some gradual development of this system, and a tropical depression could form over the next several days while it moves generally northwestward over the northwestern Caribbean Sea and the southern Gulf of Mexico. Interests along the U.S. Gulf Coast should continue to monitor the progress of this system. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...medium...40 percent. Eastern Tropical Atlantic (AL91): Showers and thunderstorms show some signs of organization in association with a broad area of low pressure located a few hundred miles south of the Cabo Verde Islands. Environmental conditions appear conducive for further development of this system, and a tropical depression is very likely to form during the next few days while it moves slowly westward over the eastern tropical Atlantic. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 7 days...high...90 percent. $$ Forecaster Pasch

Tropical Storm Kirk Forecast Discussion Number 6
2024-10-01 04:34:38| National Hurricane Center (Atlantic)
Issued at 1100 PM AST Mon Sep 30 2024 000 WTNT42 KNHC 010234 TCDAT2 Tropical Storm Kirk Discussion Number 6 NWS National Hurricane Center Miami FL AL122024 1100 PM AST Mon Sep 30 2024 Satellite images indicate Kirk is an asymmetric tropical storm with curved bands of deep convection primarily over the eastern half of the circulation. Recent scatterometer winds indicate the center of Kirk is slightly north of previous estimates, with a large tropical-storm-force wind field over the eastern semicircle. Based on the scatterometer data and a blend of the various satellite intensity estimates, the initial intensity is held at 50 kt. Kirk is now moving west-northwestward (285/10 kt). This general motion should continue for the next couple of days while Kirk moves around the southwestern periphery of a deep-layer subtropical ridge over the eastern Atlantic. A gradual turn toward the northwest is anticipated during the middle part of the week, followed by a recurvature to the north-northwest and north over the central Atlantic by the end of the 5-day forecast period. The track guidance remains in very good agreement, and only minor adjustments were made to the NHC track forecast. Very warm waters, weak vertical wind shear, and a moist environment should support steady to perhaps rapid strengthening of Kirk during the next several days. The tropical storm is currently broad and lacks an inner core, but the forecast shows a faster rate of strengthening by midweek as Kirk is expected to become better organized within this favorable environment. No significant changes were made to the NHC intensity forecast, which lies on the higher side of the guidance envelope in best agreement with the statistical-dynamical aids and some of the regional hurricane models. The models agree that the wind field of Kirk will grow quite large later in the period as the cyclone gains latitude over open waters. Ultimately, Kirk is forecast to become a large, major hurricane over the open central Atlantic later this week.
