800 AM EDT Tue Sep 10 2019
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Tropical Storm Gabrielle, located over the far north Atlantic Ocean.
- A weak area of low pressure, associated with a tropical wave located a little more than 900 miles east of the Lesser Antilles is producing disorganized showers and thunderstorms. Although some slight development of this system is possible today or tomorrow, by Thursday, upper-level winds are forecast to become unfavorable for tropical cyclone formation. This disturbance is expected to move slowly westward across the tropical Atlantic Ocean for the next several days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.
- Shower activity associated with a surface trough interacting with an upper-level low near the north coast of Hispaniola northeastward over the southwestern Atlantic has increased a little since yesterday. Little, if any, development of this disturbance is expected during the next few days while it moves west-northwestward across the Bahamas and the Florida peninsula. However, environmental conditions could become a little more conducive for development when the system moves into the Gulf of Mexico over the weekend. Regardless of development, this disturbance will produce periods of locally heavy rainfall across the Bahamas through Thursday, and across Florida on Friday and continuing into the weekend.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.
- A tropical wave located just off the west coast of Africa is expected to move quickly westward during the next several days. Some slow development is possible late this week and over the weekend when the system is several hundred miles east of the Lesser Antilles.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
