The rains may affect the second day of the Atlanta Dogwood Festival. While temperatures should reach the mid-70s, those planning on going to Piedmont Park on Sunday should probably pack their umbrellas and ponchos.

The good news is that the dogwood trees are blooming now, which is rare as the trees don’t always flower during Atlanta’s annual event.

Speaking of flowering trees, Sunday’s wet weather should bring some welcome relief for allergy sufferers.

Saturday’s pollen count reached 6,575 particles per cubic meter of air, which is considered “extremely high.”

“The pollen count has gone way up,” Deon said. “We need the rainfall to wash this out.”

Cobb County drivers should note that the Georgia Department of Transportation is resurfacing stretches of I-75 and I-285 this weekend.

Crews will work along the 11-mile stretch of I-75 from the Chattahoochee River in Fulton County to just north of Allgood Road and along I-285 eastbound over I-75 to just west of the Chattahoochee River bridge.

The project caused major delays Saturday morning and is scheduled to continue through 5:30 a.m. Monday.

The Braves host the New York Mets at SunTrust Park on Sunday evening, and game traffic may further complicate the commute for drivers on Cobb’s interstates.

Weather permitting, first pitch is scheduled for 7:08 p.m.

While road work and Major League Baseball may cause delays near Smyrna, construction will likely stifle North Fulton traffic where Ga. 400 meets I-285.

Two rights lanes of Peachtree Dunwoody Road will be blocked from I-285 to Lake Hearn Drive until 7 p.m. Sunday, according to the Georgia Department of Transportation. Traffic pacing will also be in effect for Ga. 400 in both direction between Northridge Drive and Lenox Road from 6 a.m to 1 p.m. Sunday.
