"We may have the wettest climatological fall we've ever had in Atlanta," Taylor said.
More rain fell throughout the metro area on Tuesday, prompting a flood watch for dozens of counties that ended in the early evening.
Although no major flooding was reported, the Weather Service issued a flood warning for Big Creek near Alpharetta. The warning affects both Fulton and Forsyth counties and lasts until Thursday morning. At 2:30 a.m. Wednesday, the water level in the creek was 7.59 feet. Flood level is 7 feet, and the water was expected to rise another inch or two later Wednesday morning, meteorologists said.
That level is still far below the 15.41 feet the creek reached during September's record floods.
High temperatures reached only the 50s on Tuesday, but expect a warmer Wednesday, Taylor said.
"Believe it or not, after the morning, clouds should be decreasing," Taylor said. "If we're lucky, we should see some sunshine by the afternoon."
But don't put away the umbrellas yet. Showers will return by Thursday night or Friday, and there's a 50 percent chance of rain for Halloween night.
