Heat Advisory, Excessive Heat Watch Issued For Maryland

MARYLAND — A heat advisory and an excessive heat watch have been issued for much of Maryland.

Heat indices will range from 100 to 110 degrees Wednesday and Thursday, according to the National Weather Service, which issued the alerts.

The heat advisory and heat watch apply to the Baltimore-Washington areas, northern Virginia, southern Maryland and the eastern panhandle of West Virginia.

These areas in Maryland are under the heat advisory and excessive heat watch:

• Anne Arundel County
• Baltimore City
• Baltimore County
• Calvert County
• Carroll County
• Cecil County
• Charles County
• Harford County
• Howard County
• Montgomery County
• Prince George's County
• St. Mary's County

From noon to 8 p.m. on Wednesday, the heat advisory is in effect. Temperatures will be 100 degrees on the heat index west of Interstate 95 and 105 degrees on the heat index east of I-95, the advisory states.

A heat advisory is issued closer to the time of an event, while a watch indicates something further out.

On Thursday, when the excessive heat watch takes effect, officials say "dangerously hot conditions" may drive heat indices from 105 degrees west of I-95 to 110 degrees east of I-95.

"Extreme heat and humidity will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities," the weather service advised.

Here are ways to stay safe in the heat:

• Hydrate.
• Stay in air-conditioning.
• Remain out of the sun.
• Do not leave children or pets unattended in vehicles.
