All public schools in Prince George’s County will close early on Wednesday because of the hot weather, and two schools in the county will close for the full day, officials said. At least two other Maryland jurisdictions said they would dismiss classes early at some of their schools.

In Prince George’s County, the school system said all schools would be dismissed two hours early “due to high temperatures.” Two schools in Prince George’s County — Margaret Brent Regional in New Carrollton and Riverdale Elementary in Riverdale — will close for the day because of repairs to their air conditioning systems.

The school system said the matter would be reassessed on Thursday.

All schools in Prince George’s have air conditioning, a school system spokesman said. However, he said, “40 schools had different levels of problems “ with their air conditioning.

It was necessary to close all schools to coordinate transportation for all students, the spokesman said.

Temperatures in the Washington area were abnormally high Tuesday.

In Baltimore, the school system said several schools that have air conditioning systems under repair would send students home three hours early.

Baltimore County listed 10 schools and centers that were to close early on Wednesday. It said the shortened days were the result of “forecasted excessive heat.”
