Widespread showers and thunderstorms put a damper on Memorial Day activities, compliments of a low-pressure system that extended across Florida.

Showers and thunderstorms associated with a broad area of low pressure are over extreme Northeast Florida, adjacent Atlantic waters and the northwestern Bahamas, according to a 9 a.m. advisory from the National Hurricane Center.

Although a weak surface low has formed within the trough near Orlando, little if any further development of this system is expected.

The broad disturbance is forecast to move north today and Wednesday, remaining inland or near the coasts of northeastern Florida and Georgia.

Regardless of development, heavy rainfall could cause flash flooding over portions of coastal sections of Northeast Florida and Georgia today, and over portions of the Carolinas today and Wednesday.

Gusty winds could produce rough marine conditions and life-threatening surf and rip currents along the coasts of northeastern Florida, Georgia and the Carolinas through Wednesday.

Formation chance through 48 hours: low, 20 percent.

Formation chance through 5 days: low, 20 percent.
