After a fiery Friday and an expected sizzling Saturday, D.C. is reminding residents and visitors heading to the National Mall for the festival marking the 50th anniversary of the Apollo 11 moon landing to be prepared.
“People should not underestimate the heat,” said Christopher Rodriguez, director of the D.C. Homeland Security and Emergency Management Agency.
The National Weather Service issued an excessive heat warning Friday, and that warning returns Saturday from 11 a.m. to 9 p.m. The extreme conditions are expected to stretch into Sunday.
Friday’s excessive heat warning lasts until 9 p.m., but even when night falls, the area will only cool off into the mid-70s and low 80s.
By Saturday morning, around 7-8 a.m., Storm Team 4 meteorologist Amelia Draper said it will already feel like 90 degrees, likely climbing into the triple digits by lunchtime.
Periods of high heat and humidity can cause medical problems, such as heat exhaustion and stroke.
“We want to make sure that the folks who come out for that event are properly hydrated,” Rodriguez said. “We’ll work with the Park Police to distribute water, and we’ll be on the lookout for anyone who might be suffering from heat exhaustion.”
Rodriguez said his agency will work to ensure that people know where to go if they are feeling the effects of the heat and need to cool off.
“This is going to be a pretty severe weather event, so we want to make sure people are aware of that and don’t take that for granted,” he said.
The festival kicked off Thursday between 4th and 7th streets, and returns from 9 a.m. to 8 p.m. Saturday. The festival is in addition to the Friday night and Saturday night 17-minute film that recreates the Apollo 11 launch.

D.C. Mayor Muriel Bowser has activated the District’s Heat Emergency Plan, opening cooling centers, and extending service hours for low-barrier shelters and select outdoor pools and splash parks.
