Heat to Feel Like 104 Degrees in Baltimore County

Several areas in central Maryland, including Baltimore County, are under a heat advisory Monday. Environmental officials have also issued an air quality alert for the Baltimore metropolitan region.

The National Weather Service issued the heat advisory from noon to 8 p.m. for parts of Baltimore, Harford, Howard, Montgomery, Prince George’s, St. Mary’s, Calvert and Charles counties as well as areas in Virginia and the District of Columbia.

A heat advisory means that high temperatures and humidity will create an environment where heat-related illnesses are possible. While temperatures will be in the mid to upper 90s, they will feel up to 109 degrees across the region.

To stay safe, people should make sure they are hydrated; reschedule strenuous activities to the early morning or evening; wear loose-fitting clothing; and take frequent breaks in the shade or air conditioning if working outside.

If people start feeling ill, they should be moved to a cool, shaded location. Call 911 if concerned about heat stroke.

Air Quality Alert

Sensitive groups including children, the elderly, asthmatics and those with heart and lung conditions should avoid strenuous activity and outdoor activity on Monday due to the concentration of pollution particles in the air, according to the Maryland Department of the Environment.

The department issued an air quality alert Monday, deeming the air “code orange,” or unhealthy for sensitive groups.
