BALTIMORE (WJZ) —  Another hot day is ahead Tuesday as temperatures continue to hold in the 90s and it’ll feel like it’s 100 degrees or more. A heat advisory remains in effect from 11 a.m. to 8 p.m. for southern Maryland and the Eastern Shore.

The counties included in the advisory are Caroline, Calvert, Cecil, Charles, Dorchester, Kent, Queen Anne’s, St. Marys, Somerset, Talbot, and Wicomico.

The heat index could reach up to 106 degrees in those areas. Hot temperatures and high humidity may cause heat illnesses to occur.

Baltimore City also issued a Code Red Extreme Heat Alert for Tuesday.

There’s also the potential for an afternoon thunderstorm. Much of Maryland, including areas east of Hagerstown and west of Salisbury, including Baltimore and Washington, D.C., are under a marginal risk for severe weather.

At a worksite in Baltimore, empty water bottles covered the ground as workers tried to stay cool and hydrated in the heat.

Equipment operator Brandon Clagatt said he knows firsthand what heat exhaustion feels like.

“I got real tired around 1 o’clock to the point I wanted to doze off and that’s when I knew it was getting hot out and the boss did shut it down,” he said.

Avery Cheley is in his fifth summer working outside, and on every hot day, he listens to what his body needs.

“You kind of learn the tricks of the trade staying cool,” he said. “Mostly we find spots around the building where the shade is at and sit there 15 minutes to cool down a little bit then get back to it.”

Their site supervisor gives them freeze pops to keep them hydrated and energized on hot days. They also start work early to make sure they’re done by the time the hottest temperatures of the day arrive.

It’s not just humans that need extra attention on hot days; pets can suffer burned paws if the pavement they’re walking on is too hot.

Vehicles, too, may see adverse effects from the heat: just last week, AAA reported more than 41,000 calls for service because of batteries and tires alone.

“Make sure your batteries and tires are good. Because of the heat, your tires expand and they tend to pop,” Garland Amaker from the Baltimore AAA said.
