000 ABNT20 KNHC 041128 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Sun Oct 4 2020 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Gamma, located just north of the Yucatan Peninsula over the extreme southern Gulf of Mexico. A tropical wave accompanied by a low pressure system is located over the central Caribbean Sea a couple of hundred miles southeast of Jamaica. The associated shower and thunderstorm activity is beginning to show some signs of organization. Environmental conditions are expected to be conducive for additional development, and a tropical depression is likely to form within the next day or two. The system should move west-northwestward at 10 to 15 mph across the central and western Caribbean Sea today through Tuesday, and then move into the southern or southeastern Gulf of Mexico on Tuesday night and Wednesday. Locally heavy rainfall and gusty winds will be possible across portions of Hispaniola, Jamaica, Cuba, and the Cayman Islands during the next few days, and interests on those islands should monitor the progress of this disturbance. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...80 percent. Disorganized showers and thunderstorms continue in association with a tropical wave located over the central tropical Atlantic. This system has not become any better organized, and any development during the next day or so should be slow to occur while it moves west-northwestward or northwestward at 10 to 15 mph. Significant development is not expected beyond that time due to the system moving into a region of strong upper-level winds. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. An area of disorganized showers and thunderstorms over the central Atlantic about 1000 miles east-southeast of Bermuda is associated with a surface trough of low pressure. This system is expected to move toward the west-southwest at around 10 mph, and some slow development is possible during the next couple of days before it too encounters strong upper-level winds. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. $$ Forecaster Brown
