A jet stream over the Gulf of Mexico will likely reach an area it doesn't typically hit: the Southeastern United States.
Beginning this weekend into Monday and Tuesday, widespread rainfall across the region could result in 4 to 6 inches of rain, the National Weather Service said. Isolated spots are expected to see as much as 12 inches of rain.
Florida, Tennessee, Georgia, South Carolina, and North Carolina are forecast to see most of the effects of the atmospheric river.
The chances of rain in the area "will increase later this weekend, with the potential for heavy rainfall Monday through Tuesday, which could result in flooding," the NWS said early Saturday.
