A tropical wave is currently located just off the west coast of Africa. Environmental conditions are forecast to be conducive for gradual development, and a tropical depression is likely to form late this week or this weekend while the system moves generally westward at 10 to 15 mph across the eastern and central tropical Atlantic.
* Formation chance through 48 hours...low...10 percent.

A non-tropical area of low pressure is expected to form east of the Florida peninsula late this week. This system could acquire some subtropical characteristics by this weekend while it moves generally northward. Regardless of development, this low is likely to bring gusty winds to gale force, heavy rain, and high surf to portions of the Southeast and Mid-Atlantic United States late this week and into this weekend.
