Disorganized showers and thunderstorms are associated with a broad area of low pressure located several hundred miles southwest of the Cabo Verde Islands. Environmental conditions are forecast to be conducive for further development of this disturbance, and a tropical depression is likely to form around midweek while it moves westward to west-northwestward at 5 to 10 mph over the central tropical Atlantic. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...high...80 percent. A tropical wave is expected to move off of the west coast of Africa later today. Upper-level winds are forecast to be conducive for gradual development thereafter, and a tropical depression is likely to form in a few days while the system moves westward to west-northwestward at 10 to 15 mph over the far eastern tropical Atlantic. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...high...80 percent. $$ Forecaster Reinhart
