A flash flood watch went into effect for most of north Georgia Monday night and lasts through 2 p.m. Wednesday.

Flooding caused problems on roadways Monday afternoon. Several lanes of GA 400 northbound were blocked by flooding in the road at Windsor Parkway before the afternoon commute.

Two to four inches of rainfall are possible over the next few days, Severe Weather Team 2's Brad Nitz said.

"We expect widespread 2-4" rainfall totals (on top of what we saw over the weekend, 1-4" in many spots) through Wednesday," Severe Weather Team 2's Brian Monahan said

There is also a marginal risk of severe storms across the southern half of the area on Wednesday. Storms with locally strong wind gusts are the biggest threat, Monahan said.

Heavy rains causes flooding:

Monahan went to Clayton County Monday where he found a park underwater in Morrow.

When he arrived a Paradise Park, he found the park’s playground, baseball field and basketball court under several inches of water.

Monahan said the water had started to recede from the parking lot.

He described one of the baseball outfields looking more like a swampy marsh from the heavy rain.

Monahan spoke with neighbors who said they were frustrated because the park floods after every heavy rain.

The rain will start to clear, making way for nice weather starting late Thursday through much of Memorial Day weekend.

Temperatures will be cool on Thursday – in the low to mid 70s – but warm toward 90 degrees over the weekend.

Blown transformer impacts school:

Elementary school students had to been evacuated Monday morning after a transformer blew.

“I just got a phone call from the teacher saying the power is out and the kids are getting hot and we need to come pick them up if possible,” parent Aaliyah Graham told Channel 2’s Tyisha Fernandes.

The day had started out fine at McGarrah Elementary School, but Monday’s storms blew the transformer nearby.

Fernandes was there when Georgia Power crews arrived to restore power.

Staff and students were left without air conditioning, so teachers started calling parents.

Hundreds of parents couldn’t leave work to pick up their children, so the school implemented an emergency meal plan to feed the children.

Backup generators did kick on at the school.

Parts of Atlanta saw weather damage after strong winds and rain moved through this weekend.

Channel 2’s Rikki Klaus went to one neighborhood in southwest Atlanta Sunday afternoon where an old oak tree snapped, and landed in the yard next door.

The tree brought down power lines along Carter Avenue.
