Jaxson Russen, of Delmar, takes a leap to cool off and beat the heat at the George Murphy Community Pool on Tuesday afternoon.

DENTON — The National Weather Service in Mount Holly, N.J., is forecasting extreme heat for the Mid-Shore Wednesday through Sunday.

Heat index values near or above 100 degrees will be possible Wednesday and Thursday, potentially reaching as high as 110 degrees on Friday and 115 degrees on Saturday. It is expected to be hot and humid from Wednesday through the weekend. The heat is expected to peak Friday, Saturday and Sunday.

“It is important for people to realize the danger of extreme heat especially over a prolonged period of time and to take basic precautions to ensure their well-being,” said Clay Stamp, Talbot County Department of Emergency Services director.

There is an expectation of hot and humid weather through Thursday, and excessive heat is possible from Wednesday through Sunday. Heavy rain and flooding is possible Wednesday night into Thursday as the remnant low of Barry passes through the region.

Scattered thunderstorms are expected Thursday. Otherwise, the probability for thunderstorms will remain low each day through the weekend (and be primarily in the afternoon or evening.)

A break in the hot weather pattern as well as increased chances for thunderstorms may occur Monday or Tuesday next week.

According to the Centers for Disease Control and Prevention, the body normally cools itself by sweating. During hot weather, especially with high humidity, sweating just isn’t enough.

Body temperature can rise to dangerous levels and you can develop a heat illness. Most heat illnesses occur from staying out in the heat too long.

Exercising too much for your age and physical condition are also factors. Older adults, young children and those who are sick or overweight are most at risk. Drinking fluids, replenishing salt and minerals and limiting time in the heat can help.

Heat-related illnesses include heatstroke, which is a life-threatening illness in which body temperature may rise above 106 degrees in minutes; symptoms include dry skin, rapid, strong pulse and dizziness.

Heat exhaustion is an illness that can precede heatstroke; symptoms include heavy sweating, rapid breathing and a fast and weak pulse. Heat cramps include muscle pains or spasms that happen during heavy exercise. Heat rash is skin irritation from excessive sweating.

“Talbot County has been in contact with our partnering agencies in order to support our residents during the next few days of extreme heat and high humidity. We are getting daily updates from our local National Weather Service office,” said Stamp.

General recommendations include:

• People and animals should stay indoors, especially the very young and elderly who are more prone to heat related medical emergencies.

• If you don’t have air conditioning, go to the malls or stores, cooling locations, or public buildings.

• Drink more fluids, but avoid alcohol and high sugar drinks.

• When going out, wear light clothing and never leave any persons, especially infants or young children, or animals in a closed, parked vehicle.

• Although anyone at any time can suffer from heat-related illness, some people are at greater risk than others. Check regularly on infants and young children, people aged 65 or older, people who have a mental illness, those who are physically ill, especially with heart disease or high blood pressure

• Consider visiting adults at risk at least twice a day and closely watch them for signs of heat exhaustion or heat stroke. Infants and young children, of course, need much more frequent watching.
