NWS National Hurricane Center Miami FL
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Hurricane Florence, located over the western Atlantic Ocean, on Hurricane Helene, located over the eastern Atlantic Ocean, on Tropical Storm Isaac, located near the Lesser Antilles, and on Subtropical Storm Joyce, located a little less than a 1000 miles west-southwest of the Azores.
1. A trough of low pressure located over the western Gulf of Mexico is producing disorganized showers and thunderstorms. While upper-level winds are generally conducive for the development of a tropical depression, the system only has about a day before it reaches the western Gulf coast. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the disturbance later today, if necessary. Regardless of development, heavy rainfall and gusty winds are expected across portions of northeastern Mexico, Texas, and Louisiana on Friday and Saturday. Interests there should monitor the progress of this system, and refer to products from their local weather office.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.
2. An area of low pressure is expected to develop near Bermuda late this weekend or early next week. Some gradual development is possible after that time while the system drifts westward over the western Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
