One good thing about the former hurricane that knocked out power to thousands is the cooler temperatures left behind when Hermine moved up the east coast.

An estimated 20,000 people in the Savannah area and surrounding southeast Georgia counties were without power Saturday, after Hermine was downgraded to a tropical storm Saturday.

High pressure on Sunday was strengthening over the southeast, bringing drier air and more sunshine to Atlanta for Labor Day weekend, Channel 2 Action News meteorologist Katie Walls said.

“The downside of the stretch of dry weather ahead is that it’ll worsen our already severe and extreme drought,” Walls said.

Sunday started out in the high 60s across metro Atlanta, which are the coolest temperatures people have felt in more than two months.

At 70 miles per hour and about 300 miles from Ocean City, Maryland, on Sunday, Hermine was considered a post-tropical cyclone before noon, Walls said.

Like Hurricane Sandy, this storm will majorly impact the Mid-Atlantic and Northeast from Virginia to Massachusetts, where tropical storm warnings are in effect, Walls said.

“Serious coastal flooding, high winds and large waves will inevitably cause destruction, keeping Hermine in the news this week,” Walls said.

Temperatures were 85 degrees in Atlanta, 81 degrees in Blairsville and 89 degrees in Griffin just before 6 p.m.
