For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
- Showers and thunderstorms associated with a tropical wave are gradually moving westward away from the Lesser Antilles. Although the disturbance remains disorganized at this time, some gradual development of this system is possible during the next several days while it moves westward at 15 to 20 mph across the Caribbean Sea. Regardless of development, this system will continue to produce gusty winds and locally heavy rainfall across portions of the Windward and Leeward Islands this morning before diminishing this afternoon.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.
- A westward-moving tropical wave is located over the eastern Atlantic Ocean, several hundred miles southwest of the Cabo Verde Islands. This system is producing limited shower activity, and any further development is expected to be slow to occur while it moves slowly westward over the eastern or central tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.
- An area of low pressure is expected to form off the southeastern coast of the United States in a day or two. Subsequent development of this system is possible, and a tropical depression is likely to form by the middle of the week while the system moves northeastward or east-northeastward, initially parallel to the southeastern coast of the U.S. and then away from land.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.
- A new tropical wave is expected to emerge off the coast of Africa in a couple of days. Some gradual development of this system will be possible through the end of the week while it moves slowly westward over the far eastern tropical Atlantic Ocean.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
