Maryland made it through another oppressively hot day. But the impact of the weather was clearly felt.

Marylanders roasted again as the region sweltered, with the temperature hitting 100 degrees in some areas.

“It’s hot. It’s really hot,” Alex Hickey said.

A heat advisory for much of the state had those outside trying to stay cool, and those inside trying to avoid going out. Staying hydrated and taking breaks were a must.

Thursday’s hot weather was intense and officials say it did produce some heat-related injuries.

The cases included an 11-year-old girl in Kent County who burned her bare feet walking on metal stairs.

“Obviously, on hot days like this we have an increase in patients that are coming in with heat strokes,” Dr. Peter Andrews, a physician’s assistant at Sinai Hospital, said.

The hot weather puts a strain on people and the power grid.

Baltimore Gas and Electric (BGE) says customers heeded warnings about conserving energy in an effort to avoid the worst case scenario of a brownout.

“Our grid was actually able to handle the heat and handle the stress from increased usage very well,” Rachael Lighty, a spokesperson for BGE, said.

The tough job of firefighters is even harder when they have to put on hot, heavy gear to battle fires.

Those who do yard work for a living also felt the heat.

“It pays the bills. you know. But yeah, I would advise nobody be out here,” Melvin Turner of Baltimore said.

In Baltimore, one person was taken to the hospital and treated for a heat-related illness.

Health experts are also warning those with respiratory issues or heart conditions to be aware of the air quality.

Eleven cooling centers will be open in Baltimore for those who need them. They open at 9 a.m. and close at 7 p.m.
