Multiple wrecks — and even a dangling car — have slowed traffic to a crawl across the metro area on this dry, warm and overcast afternoon.

A car is dangling above the I-20 westbound ramp to the Downtown Connector in Atlanta. The ramp is blocked and traffic is starting to back up in the area.

An overturned dump truck on I-75 South past Wade Green Road in Cobb County has caused a big jam and multiple lanes have closed, according to the WSB 24-hour Traffic Center.

There are also lingering backups on I-75 North near Barrett Parkway in Cobb as the result of a wreck involving a tractor-trailer, the Traffic Center reported. Debris has been cleared and all lanes are back open, but traffic was gridlocked back to I-285 earlier this afternoon.

A passenger issue at Five Points has caused 10-minute delays on MARTA’s Gold and Red lines, MARTA said in a tweet.

The evening commute could also be impacted by those heading to the Fox Theatre to see “Hamilton” and to the Verizon Amphitheatre in Alpharetta for the Poison and Cheap Trick concert.

Metro Atlanta warmed up after Tuesday got off to a comfortable start with temperatures in the 50s and 60s in parts of North Georgia. An overcast sky has kept Atlanta cooler than expected, and the temperature is currently 82 degrees.

Channel 2 Action News meteorologist Brian Monahan said Atlanta hadn’t seen temperatures this cool since May 11.

The clouds will start to push out later this evening, Monahan said, so North Georgia should wake up Wednesday to another comfortable morning with mostly clear skies.

The sunshine is expected to stick around through the rest of the week, but more rain is forecast for the weekend. Saturday’s chance of rain is 30 percent, while Sunday has a 40 percent chance.

“There are some storms for the weekend. It’s not going to be a washout, though,” Monahan said.

The storms will be isolated Saturday and more widespread Sunday, Channel 2 reported.

Even though this week is dry and sunny, authorities say people should not let their guard down when boating or swimming in Georgia’s waterways. Several popular swimming areas are closed at Lake Lanier, and it might be at least a couple of weeks before they reopen, The Atlanta Journal-Constitution previously reported.

The U.S. Army Corps of Engineers has advised that any swimming or boating in the Chattahoochee River is unsafe due to high water levels and turbulent flows.

“At 1,074.69 feet, Lake Lanier is the highest it’s been in any June going back to at least 1960,” Monahan said. “Heavy rain from the last several weeks — including more than a foot over parts of the Hooch in northeast Georgia — continues to flow down into the lake.”
