Although the disturbance is not well organized 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 through the Lesser Antilles and across the Caribbean Sea. Regardless of development, this system will likely produce gusty winds and locally heavy rainfall across portions of the Windward and Leeward Islands today. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...low...30 percent. Another tropical wave is located over the eastern Atlantic Ocean, several hundred miles southwest of the Cabo Verde Islands. This system is producing very limited shower activity, but some development will be possible later this week over the eastern or central tropical Atlantic while it moves slowly westward. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...medium...40 percent. An area of low pressure is expected to form off of the southeastern coast of the United States in a day or two. Subsequent development of this system is possible and a tropical depression could 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...40 percent. * Formation chance through 5 days...medium...50 percent. $$ Forecaster Zelinsky
