000 ABNT20 KNHC 022334 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Thu Sep 2 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Hurricane Larry, located over the eastern tropical Atlantic several hundred miles west of the southernmost Cabo Verde Islands. A small area of low pressure and associated surface trough over eastern Honduras is producing disorganized shower and thunderstorm activity over portions of the western Caribbean Sea. A portion of the low's circulation could move over the Gulf of Honduras on Friday. However, development there, if any, is expected to be slow to occur. This system could then move over the southwestern Gulf of Mexico during the weekend, but by then unfavorable upper-level winds are likely to limit significant development early next week while the system moves northwestward or northward over the western Gulf of Mexico. Regardless of development, heavy rains are possible across portions of Central America and the Yucatan Peninsula through the weekend. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent. Showers and thunderstorms associated with an area of low pressure located a couple of hundred miles southeast of the southernmost Cabo Verde Islands continue to show some signs of organization. Some limited development of this system could occur tonight and on Friday as the low moves generally westward at 10 to 15 mph. After that time, conditions are expected to become less conducive for development. Interests in the Cabo Verde Islands should monitor the progress of this system. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...low...30 percent. $$ Forecaster Brown
