Sunday afternoon, the National Hurricane Center identified three areas of concern:
1. Western Atlantic (AL95): Showers and thunderstorms have increased in association with a non-tropical area of low pressure located a few hundred miles east of the North Carolina coast. While satellite wind data show that the low is now producing gale-force winds, the system remains attached to a frontal boundary. However, environmental conditions are conducive for this system to acquire additional tropical characteristics, and a tropical storm is likely to form by Monday well east of the North Carolina coast.
Formation chance through 48 hours are high at 70%.
Formation chance through 7 days are high at 70%.
2. Central Tropical Atlantic: A tropical wave is forecast to move off the west coast of Africa by late Monday. Thereafter, some gradual development of the wave is possible, and a tropical depression could form late this week while it moves generally west-northwestward across the central tropical Atlantic.
Formation chance through 48 hours are low near 0%.
Formation chance through 7 days are medium at 40%.
3. Off the Southeastern United States: An area of low pressure could form in a couple of days a few hundred miles southeast of the Carolinas. Some gradual development of this system is possible by midweek as the system drifts to the northwest.
Formation chance through 48 hours are low near 0%.
Formation chance through 7 days are low at 20%.
