It was a whirlwind weather day for metro Atlanta.

A morning of heavy rain brought strong winds and downed trees.

The afternoon wasn’t much better.

The National Weather Service issued tornado warnings for Henry and Rockdale counties. Those warnings expired and gave way to thunderstorm warnings in DeKalb and Rockdale counties.

The bright spot? No severe damage was reported during the warnings, which were canceled before 4:45 p.m.

Other parts of metro Atlanta may not be as lucky.

While the heavy rain has subsided for now and become more scattered, a flood warning has been extended in Forsyth and Fulton counties.

The warning, originally set to expire Tuesday night, is now set to last through Wednesday afternoon, according to the NWS.

A warning means flooding is imminent. A watch means conditions are favorable for flooding.

There is a 40 percent chance or rain Tuesday. Atlanta is also expected to reach a high of 70.

By 10 a.m. Monday, the water level at Big Creek near Alpharetta had reached 7.1 feet, which is just above the 7-foot flood stage, according to the weather service.

The water is expected to "continue to rise to near 8.3 feet by this evening," the weather service said in a statement.

Earlier, a tree fell on a house on Woodacres Road in Chamblee, according to Channel 2. A man was sleeping in the home but was not injured.

The Atlanta Police Department received reports of flooding at 335 Fairburn Road and at the intersection of Ralph David Abernathy and Joseph E. Lowery boulevards.

Currently, 1,203 Georgia Power customers are without service, according to the agency.

Beyond power outages and downed trees, the rain has not had a major impact on North Georgia or resulted in serious crashes or injuries so far.

There have been some positive benefits from the wet weather. Atlanta has received about 1.96 inches of rain since showers started Sunday, Channel 2 meteorologist Katie Walls said in a tweet.

All that rain washed away the pollen, sending the count from 681 particles per cubic meter of air Sunday to 30 Monday, according to Atlanta Allergy and Asthma.

Both totals are well below this season’s high of 5,354.

Currently, the temperature is 64 degrees.
