Scorching temperatures and stifling humidity are expected to continue in the Washington area through Tuesday.
The National Weather Service has extended a heat advisory until 8 p.m. Tuesday, and regional officials have declared Monday and Tuesday Code Red days for poor air quality. Temperatures are expected to reach 95 to 100 degrees both days. It could feel more like 105 with the humidity.
Children and people with respiratory or heart ailments are advised to limit outdoor activities on Code Red days. Healthy people should limit strenuous outdoor work and exercise. Residents are also encouraged to limit driving, and bus rides in the D.C. suburbs are free.
Meanwhile, more than 2,000 people are still without power following last week's storm.
