Formation chance through 48 hours...high...70 percent and formation chance through 5 days...high...90 percent.

Disturbance 2. Central Subtropical Atlantic

A well-defined low pressure area is located several hundred miles east of Bermuda. A short-lived tropical depression or storm is likely to form later today while the system drifts slowly over the central Atlantic. Thereafter, the system is forecast to turn northeastward and merge with a strong cold front by the middle part of this week. Formation chance through 48 hours...high...70 percent and formation chance through 5 days...high...70 percent.
