Ahead of Sunday’s high temperatures and storms, 7News First Alert Meteorologist Mark Peña highlighted the impact that increasing temperatures could have around the region.
“Take the heat alerts seriously. This level of rare and/or long-duration extreme heat with little to no overnight relief affects anyone without effective cooling and/or adequate hydration,” he said.
Showers and thunderstorms are also expected around the region later Sunday evening and could remain around the D.C. metro area through early Monday morning.
Peña reports that some of these storms “could be on the strong to severe side” and advised caution when planning outdoor activities this evening.
Monday morning temperatures are expected to linger on the cooler side with less humidity and a brief return to 90-degree days.
Outages:
Saturday’s heat continued to prove challenging for residents in the District, with thousand reportedly without power in the Petworth area and parts of Prince George’s County, Maryland.
A spokesperson for Pepco, the major utility provider for D.C. homes, told WTOP power crews are on the ground working to restore electricity.
“There are scattered underground issues that are impacting customers in the District and Prince George’s Counties. Our crews are investigating the cause and will work safely and quickly to restore power to impacted customers,” the utility said.
Pepco couldn’t confirm if heat or another factor was behind the outage, saying the issue remains under investigation by its crews. Customers impacted by the outage should see power restored before 7 a.m.
Loudoun County, Virginia, residents are also dealing with power outages caused by a downed power line amid the heatwave. Officials expect power to return to most customers by 5 a.m. on Sunday.
Anyone who notices downed power lines or damaged equipment around their home is encouraged to maintain a safe distance and call to report the issue.
