Heat Advisory Issued For Montgomery County Thursday

ROCKVILLE, MD — A heat advisory is in effect for much of Maryland from noon to 8 p.m. on Thursday, July 13. During a heat advisory, high temperatures and high humidity create an environment where heat-related illnesses are possible. Those without air conditioning and people working outside are at the greatest risk.

Heat indices of 105 degrees are expected on Thursday, July 13, the National Weather Service says; actual temperatures will be in the mid 90s.

The hottest period of the day will be from 2 to 6 p.m., based on the forecast. Isolated thunderstorms may crop up in the afternoon and evening, weather officials said.

The following are included in the heat advisory: Anne Arundel, Baltimore, Calvert, Charles, Harford, Howard, Montgomery, Prince George's and St Mary's counties, as well as the District of Columbia and parts of Virginia.

People in sensitive groups should avoid strenuous and outdoor activities on Thursday.

How to Stay Safe in the Heat

Heat stroke, the most serious heat-related illness, can be fatal if not treated immediately. It occurs when the body's temperature rises rapidly and the sweating mechanism fails, leading to overheating without a way to cool down.
Symptoms include confusion; slurred speech; seizures; hot, dry skin or extreme sweating; altered mental status; very high body temperature; and loss of consciousness/coma. If someone exhibits signs of heat-related illness, move the person to a cool, shaded area and call 911.
Here are several ways to stay safe during the heat advisory period:

• Dress light. Wear lightweight, light-colored clothing. Light colors reflect away some of the sun's energy. It is also a good idea to wear hats or to use an umbrella.
• Drink water. Carry water or juice with you and drink continuously even if you don't feel thirsty. Avoid alcohol and caffeine, which dehydrate the body. Avoid salt tablets unless directed by a physician.
• Eat small meals and eat more often. Avoid high-protein foods, which increase metabolic heat.
• Slow down. Avoid strenuous activity. If you must do strenuous activity, do it during the coolest part of the day, which is usually in the morning between 4 and 7 a.m.
• Stay inside. If air-conditioning is not available, go to the lowest floor out of the sunshine. Remember that electric fans do not cool; they simply circulate the air.
• Be a good neighbor. During heat waves, check in on elderly residents in your neighborhood and those who do not have air conditioning.
