The national radar mosaic for the moment the first event began.
2 heavy rain, 2 flood. Local standard time, as filed.
The USGS site at the Brunswick Village Pier measured 4.76 inches of rainfall in 3 hours.
The ASOS at the St Simons Island airport measured 4.06 inches of rainfall since 6:45 pm.
Several cars stalled in Waycross due to flooded roads.
Flooded marshes overflowed onto roads on St. Simons Island likely due to the combination of heavy rainfall and high tide near a full moon. Several homes reported water almost inside and some businesses did flood. One call stalled due to flooding on the roads. About 6 to 8 inches of standing water was reported in many locations. Some of the flooded areas included the Village, Mallory Street and Ocean Blvd. Barricades where placed through the city where roads were flooded.
