The rain that moved into metro Atlanta Sunday afternoon had tapered off by Monday’s morning rush hour, but by late morning, another round of rain was approaching from Alabama.

A wide swath of the state from metro Atlanta southward to Macon remained under a flash flood watch until 1 p.m. The flood watch for extreme north Georgia was canceled after only light rain fell across those counties.

Rainfall totals through 6 a.m. Monday ranged from 1.09 inches in Marietta and 1.34 inches in downtown Atlanta to 1.56 inches at Hartsfield-Jackson International Airport, 1.61 inches in Alpharetta and 1.72 inches in Peachtree City.

South of metro Atlanta, Pine Mountain recorded 3.03 inches, while 1.91 inches had fallen in Columbus, and Macon reported 1.95 inches.

So far this year, 12.51 inches of rain has fallen in Atlanta’s official rain gauge at the airport, a surplus of 2.76 inches.

Investigators have not said whether the heavy overnight rain contributed to a multi-vehicle wreck that shut down I-285 northbound on the west side of town for a couple of hours.

A tractor-trailer hauling sewage sludge and a dumptruck loaded with sand overturned in the wreck, which happened just north of I-20. All lanes of I-285 were reopened by 5 a.m.

At 10:30 a.m. Monday, an area of light to moderate rain covered much of the northern suburbs, and stretched well back into Alabama, while radar showed heavier rain moving into south Georgia from the southwest.

Channel 2 Action News meteorologist Karen Minton said isolated showers would be likely Monday afternoon across metro Atlanta, followed by heavier rain again on Tuesday into Wednesday.

Minton put the chance of rain at 80 percent Monday, 90 percent Tuesday and 60 percent Wednesday.

Afternoon highs will be in the low 60s Monday and mid-50s Tuesday and Wednesday, with overnight lows in the mid-40s.

Thursday and Friday should be sunny, with highs in the 50s and lows in the 30s.
