Heat Advisory Issued In Maryland

MARYLAND — A heat advisory is in effect Wednesday for six jurisdictions in Maryland Wednesday, according to the National Weather Service. Authorities issue a heat advisory when the combination of high temperatures and humidity may cause heat-related illnesses to occur.

To avoid becoming ill, people should reschedule strenuous activities to the early morning or evening; drink water; and wear loose, light-fitting clothing.

Those working outside should take frequent breaks in shade or air-conditioning. Never leave children or pets alone in vehicles during a heat advisory, officials warn.

Heat indices of up to 105 degrees are expected Wednesday, according to the advisory.

The heat advisory is in effect from noon to 8 p.m. Wednesday for the following areas:

• Anne Arundel County
• Baltimore City
• Baltimore County
• Calvert County
• Cecil County
• Harford County

Temperatures across much of the state are expected to be above 90 degrees Wednesday, according to authorities.

Storms Ahead After Heat

An isolated severe thunderstorm with damaging wind gusts is possible late Wednesday afternoon and evening, mainly across the greater Washington and Baltimore metropolitan areas.

Forecasters expect thunderstorms Thursday that may bring damaging winds and heavy rain that could lead to flooding or flash flooding.

"A brief tornado can't be ruled out" on Thursday as well, according to a hazardous weather outlook from the National Weather Service.

Flood threats may continue Friday for southern Maryland.

How To Stay Safe In The Heat

If someone has signs of heat-related illness, move the person to a cool, shaded area and call 911. Put cold, wet compresses on the person if possible.

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.

Here are several ways to stay safe during the heat advisory period:

Lighten up. 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.
