Disorganized system drifts near Bermuda

Satellite images indicate that showers and thunderstorms are showing some signs of organization associated with an area of low pressure located about 400 miles southeast of Bermuda. Further development of the low is possible, and this system could become a short-lived tropical depression or storm during the next couple of days while it moves northward and north-northeastward, well northeast of Bermuda.

• Formation chance through 48 hours: Medium — 40%
• Formation chance through 7 days: Medium — 40%

Tropical wave to emerge off Africa Monday

A tropical wave is expected to move off the west coast of Africa on Monday, and an area of low pressure could form in association with the wave early this week. Environmental conditions are forecast to be marginally conducive for development, and a tropical depression could form by the middle to latter portions of the week while the system moves generally westward at 15 to 20 mph across the eastern and central tropical Atlantic.

• Formation chance through 48 hours: Low — near 0%
