The D.C. area on Monday hit record temperatures for the second day in a row, with another high of 101. The weather forced officials to shutter outdoor day camps and sporting events and prompted Prince George’s County to push trash pickup an hour earlier through September.

The Washington Post’s Capital Weather Gang forecasts the earlier half of this week is expected to reach the upper 90s and 100s through Wednesday. Elected leaders from across the region are warning residents to be careful.

“Reminder: we are in an Extended Heat Emergency through Wednesday, July 17,” D.C. Mayor Muriel E. Bowser (D) posted on X Monday morning. “Please stay cool and check on seniors and neighbors.”

The District has opened up nearly 120 cooling stations across the city for residents at community pools, community centers, and shelters for anyone in need of relief as the city braces for another week of triple-digit weather.

Luminis Health Anne Arundel Medical Center in Annapolis and the company’s Doctors Community Medical Center have seen increased numbers of patients reporting to emergency rooms with symptoms of heat exhaustion, including employees who work outdoors, according to Sunil Madan, chief medical officer at the Lanham site.

Physical conditions can deteriorate over hours if people don’t take the proper precautions to replenish fluids and to rest frequently, in cool environments if possible, Madan said.

More severe heat illnesses can result in organ failure, especially for people who suffer from co-morbidity conditions, Madan said.

“Hydrate. Take breaks. Wear sunscreen. Wear a hat,” Madan said. “The information is out there, the warnings. But I do think the public needs to be more aware and heed. It’s a serious thing.”

D.C. Fire and EMS Captain Renaldo Bell said medics have responded to treat patients dealing with cramping, heat exhaustion and, in rare cases, heat stroke. Many calls result from people who get overheated while exercising in extreme heat and children who play in pools and lie out in the sun but fail to continually hydrate.

“The pool will keep you cool, but you’re actually sweating with the energy and playing and you’re losing a lot of sodium and electrolytes,” Bell said.

The city’s pools and cooling centers help lessen the number and severity of calls, Bell said, but responders still have concerns about elderly residents who may not venture outside.

“A lot of the time the elderly don’t like a lot of air, and then it gets hotter than they expect,” Bell said. “At this point you’re dealing with the heat stroke type of environments.”

Mild heat-related symptoms include cramping from a lack of replenishment of fluids. But as conditions worsen, heat exhausted patients may feel faint, sweat profusely and deal with nausea symptoms or vomiting, Bell said. People suffering from heat stroke may have headaches, dry skin, vomiting or fall unconscious.

Maryland’s most populated county — Montgomery — has opted to not open cooling centers, but is urging residents seeking relief to head to public buildings such as libraries and community centers this week.

“We don’t specifically set up specific buildings for cooling centers because historically we believe the majority of residents have access to air conditions,” said Mary Anderson, a county spokesperson. “That said, at the drop of the hat, we are ready to set up cooling stations if, for example, we knew all of Wheaton was without power.”

Free water will be available on Montgomery County Ride On buses.

In Prince George’s County, outdoor programs have been canceled while cooling stations remain open. The county has also opted to move trash removal one hour earlier due to conditions outside. Outdoor recreational programs in Prince George’s have been canceled for Monday.

Fairfax County in Virginia has also opened cooling stations. The county school district announced all activities such as team practices and other outdoor extracurriculars have been canceled.

As of Monday afternoon, the county had not closed any camps or parks. “We continue to encourage all parents — particularly those parents of participants in outdoor camps — to make sure their child comes prepared with appropriate clothing, water bottle and sun protection,” said county spokesperson Ben Boxer.

The city of Alexandria has suspended all outdoor programming until 8 p.m. Monday. This includes organized sports and camps, according to Ebony Fleming, the chief spokesperson. The parks are still open.

Loudoun County has also not yet closed parks or community facilities, according to Kraig Troxell, a spokesperson for the Department of Parks, Recreation and Community Services. Cooling centers are open for residents.
