Active Systems: The National Hurricane Center is issuing advisories on Hurricane Danielle, located several hundred miles north-northwest of the Azores, and on Hurricane Earl, located a few hundred miles south of Bermuda. 1. Eastern Tropical Atlantic: An area of low pressure located almost a thousand miles west of the Cabo Verde Islands continues to produce disorganized showers and thunderstorms. Environmental conditions appear conducive for additional development of this system, and a tropical depression is likely to form within the next day or so while it moves westward to west-northwestward at 15 to 20 mph over the central tropical Atlantic. After that time, upper-level winds are forecast to become less conducive for development. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...70 percent. 2. West Coast of Africa: A tropical wave currently located near the west coast of Africa is forecast to emerge into the eastern Atlantic later this morning. Environmental conditions appear conducive for some gradual development thereafter as the system moves west-northwestward over the eastern tropical Atlantic. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...30 percent.
