"Temperatures can rise especially quickly inside hot cars," Maryland Deputy Health Secretary Dr. Howard Haft said in a statement Monday.

“Never leave children or pets inside a car, even for a minute, even if the windows are cracked," Haft said. "It could be deadly."

While Anne Arundel, Baltimore, Charles, Howard, Montgomery, Prince George's and Washington counties as well as Baltimore City and the District of Columbia are under the heat advisory, temperatures around the state will feel like triple digits.


There may be a record temperature set on Monday, June 18, at Dulles, where the record of 94 degrees was set in 2007. Weather officials say that BWI and Reagan airports will likely not break records, since theirs were 97 degrees for that day.

Prepare Your Vehicle

AAA Mid-Atlantic is anticipating a surge in calls for assistance from drivers as the temperature rises.

"You can bet your last money, SOS calls for roadside assistance to AAA’s switchboard will rise as the temperature rises," AAA Mid-Atlantic Roadside Assistance Manager Bruce Jenkins said in a statement Friday. "Automobile engines work extra hard in the summer or summer-like heat waves, and it is the cooling system’s job to protect the engine from overheating. When that fails to happen, you end up stranded on the roadside or stalled by the wayside."

Overheating is the most common cause of vehicle breakdowns during periods of extreme heat, according to AAA. During summer 2017, the agency said it responded to more than 1.2 million rescue calls from motorists in the DMV: 495,551 Maryland motorists; 67,937 drivers in Washington, D.C.; and 561,337 Virginia drivers.
Said Jenkins: "In this heat, the engine cooling system can fail without warning."

People are advised to drink plenty of water and pack emergency kits for their cars in case they encounter problems.
