000 ABNT20 KNHC 102347 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Fri Sep 10 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 western Atlantic several hundred miles southwest of Newfoundland, Canada. The northern part of a tropical wave is interacting with a surface trough over the southwestern Gulf of Mexico. The merger of these features is producing a large but disorganized area of showers and thunderstorms over the western Caribbean Sea, Central America, the Yucatan peninsula, and Gulf of Mexico. Environmental conditions are expected to be conducive for gradual development over the weekend, and a tropical depression is likely to form on Sunday or Monday before the system moves near or onshore of the western Gulf of Mexico coast. Regardless of development, this disturbance is expected to produce heavy rain across portions of Central America and the Yucatan Peninsula through Saturday which may lead to flash flooding and mudslides. By late this weekend, heavy rain will likely reach portions of the western Gulf coast, including coastal Texas and Louisiana through the middle of next week. Localized significant rainfall amounts will be possible, resulting in limited flash and urban flooding. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...80 percent. A strong tropical wave located just off the west coast of Africa is producing disorganized showers and thunderstorms. Environmental conditions appear generally conducive for additional development and a tropical depression is likely to form late this weekend or early next week as the system moves west-northwestward over the far eastern Atlantic near the Cabo Verde Islands. Interests in the Cabo Verde Islands should monitor the progress of this system. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...high...70 percent. $$ Forecaster Papin
