WEATHER-TRAFFIC: Concrete pumper truck tips over in Cobb, causes hazmat situation

First it was a police standoff. Then it was a car crash. Now, an overturned concrete pumper truck is affecting metro Atlanta traffic.

It’s just a normal Tuesday in Atlanta.

The vehicle toppled over at a construction site on Lake Acworth, and authorities have blocked an eastbound lane of Lake Acworth Drive as a result, according to the WSB 24-hour Traffic Center.

No injuries were reported, but a fuel spill is being cleaned by a hazmat company, Cobb County fire said.

Delays linger in Cobb and Douglas counties on I-20 after a crash blocked all westbound lanes at Ga. 92, the Traffic Center reported. The wreck has been moved to the right shoulder, but delays are still extensive.

Southside drivers are also moving again on I-75 after a police standoff nearby that shut down the interstate ended.

I-75 South past Tara Boulevard was blocked for more than two hours, but it finally reopened about 3 p.m. when the man involved in the standoff was taken into custody. Most of the delays have dissipated as of 5:30 p.m.

The Westside saw some spotty showers about noon Tuesday, and that rain moved out of metro Atlanta through Gwinnett County earlier in the afternoon. Atlanta has a 40% rain chance Tuesday.

Temps started in the 60s in town, a few degrees lower than on Monday morning. Even cooler air could move in by the weekend, dropping morning lows into the 40s in some areas, according to Channel 2 meteorologist Brian Monahan.

“That cold front that came through a couple of days ago really helped things out,” Monahan said. “It knocked us out of the 90s, back down into the 70s (for highs). Eventually these cooler snaps will help take care of the pollen season, but not yet.”

Tree and grass pollens are fairly low, but mold pollen is inching closer to extremely high territory. Now that we are settling into a more fall-like pattern, Monahan said allergy triggers shift from grass to weeds. North Georgia is looking at several more weeks of pollen season before the first hard freeze signals an end, he said.

Metro Atlanta has reached 83 degrees Tuesday, which is eight degrees above average for this time of year, according to Channel 2.

Overnight, North Georgia is forecast to turn partly cloudy and start Wednesday dry under a mixture of clouds and sunshine.

“By the afternoon, we've got sunshine in the forecast for tomorrow, and that is great news for Game 5 Braves baseball out at SunTrust Park,” Monahan said. “It should be really nice as we head toward Wednesday afternoon.”

The Braves return home Wednesday for the decisive fifth game in the National League Division Series against the St. Louis Cardinals. First pitch is at 5:02 p.m.

Temperatures should stay in the upper 70s Wednesday and Thursday as rain chances stay low, according to Channel 2. Another cold front moving in for the weekend could bring more widespread rain and much lower numbers.

“By Sunday morning, we're going to have some 40s and 50s for lows as another cold front comes in,” Monahan said.
