A flood watch has been issued for Hall and surrounding counties, starting at 8 tonight and ending Monday evening, according to the National Weather Service.
Some of the rain will be heavy, with amounts of 2 to 4 inches.
The weather service warns that, because soils are still saturated from heavy rains in late September, rainfall could run off quickly into creeks and streams, leading to rises that could flood roads and other property.
The chance for rain should ease up Tuesday, but thunderstorms are likely on Wednesday.
Sunny skies are predicted to return to the area Thursday. Temperatures are expected to rise this week, peaking at 80 degrees on Wednesday.
Lake Lanier, meanwhile, will continue to benefit from the rains of late. As of Sunday afternoon, the lake stood at 1,069.13 feet above sea level, according to the U.S. Geological Survey.
Lanier, which just two weeks ago was at 1,065 feet, has a full pool of 1,071 feet.
Full rainfall benefits typically aren't seen until a day or two after the rainfall, officials have said.
