Isaias Brings Flooding and Severe Weather Threat Further North

ORLANDO, Fla. – Hurricane Isaias made landfall near Destin in Florida’s Panhandle on Friday evening as a Category 2 storm. The system quickly weakened into a post-tropical low, losing its tropical characteristics and organized structure. Even so, its deep tropical moisture and broad circulation continue to spread northward.

A large area of rain is moving into the Tennessee Valley and eastward across the Carolinas Saturday morning. The combination of abundant moisture, the Appalachian Mountains and hilly terrain stretching from the Tennessee Valley into the Mid-Atlantic is raising the threat of flooding across much of the South. A flood watch is in effect Saturday from western Mississippi and Tennessee eastward through all of Georgia and much of South Carolina. A moderate risk of excessive rainfall, Level 3 of 4, covers areas from the eastern Atlanta metro northward into western North Carolina, while a slight risk, Level 2 of 4, includes most of Georgia and South Carolina.

In addition to heavy rain and flooding, severe weather remains a concern. Isaias’s circulation and the resulting atmospheric instability, combined with high low-level moisture and pockets of deeper convection east of the system, could support supercell thunderstorms and tornadoes. Parts of the Southeast face a slight risk for severe weather Saturday afternoon. That threat is expected to extend northward into the Mid-Atlantic and southern portions of the Northeast on Sunday.
