Shower and thunderstorm activity is limited and disorganized this afternoon in association with a broad area of low pressure located several hundred miles to the south of the Cabo Verde Islands.

While environmental conditions are currently only marginally favorable for slow development over the next couple of days, they are forecast to become more favorable by early next week. A tropical depression could form by the middle of next week as this system moves generally westward across the eastern and central tropical Atlantic.
