Wider weather episode

After making landfall in the Big Bend area of Florida as a Category 1 hurricane on August 5, Debby weakened to a tropical storm as it slowly moved across southeastern Georgia and offshore. Tropical Storm Debby then came ashore in South Carolina after stalling off the southeast coast for several days. Debby gradually progressed northward through central North Carolina and eventually into southern Virginia.

The circulation brought strong moisture advection to eastern NC priming conditions for a long duration rainfall and flash flooding event. Impacts included a widespread 3-10 inches of rain across the forecast area and flash flooding in several locations. Winds were not as much of an issue, though some gusts to tropical storm force were noted for some areas near the coast, which produced some minor tree damage. A tornado formed and touched down in Greene County, and was rated an EF-2. Storm surge was negligible.
