A meteorologist from the National Weather Service said on Wednesday afternoon that a heat advisory will be in effect on the Seacoast until 8 p.m. on Friday night and it won't cool down during the overnight hours.

"It's going to remain warm and sticky overnight so that can have a building effect on heat stress," Greg Cornwell said.

High temperatures are predicted to be in the mid-90s, with Thursday being the hottest day.

Combined with dew points in the lower to mid-70s, heat index values are expected to rise into the upper 90s.

On Wednesday and Thursday nights temperatures are expected to remain in the 70s, providing little relief.

Officials in the city of Dover are reminding people of the ways they can cool off. Here is what they have to say:

Staying cool tips

  • Stay out of the sun as much as possible. Avoid strenuous activity during the hottest part of the day and take regular breaks from physical activity.
  • Wear sunscreen and loose, lightweight, light-colored clothing to help keep cool.
  • Never leave children, seniors, pets, or people with health conditions in a parked vehicle, even briefly. Temperatures can become dangerous within a few minutes.
  • Check on your neighbors, especially seniors and people with a chronic illnesses, to see if they need assistance.
  • Use air conditioning to cool down. People who do not have an air conditioner can go to an air-conditioned public building, such as a public library or shopping mall, for a few hours.
  • Drink plenty of fluids – don't wait until you're thirsty to drink. Water is best. Avoid alcohol, caffeine and sugary drinks.
  • Be aware that some medicines affect the body's ability to sweat and stay cool. Do NOT stop taking medication unless instructed to do so by your healthcare provider.

    These are the signs of heat-related illnesses 

  • Heat exhaustion is the body’s response to an excessive loss of water and salt, usually through excessive sweating. Those most prone to heat exhaustion include the elderly, those with high blood pressure, and those working in hot environments. Symptoms include headache, nausea, dizziness, weakness, irritability, thirst, heavy sweating, elevated body temperature and decreased urine output.
  • If you are experiencing heat exhaustion, drink cool beverages, seek air conditioning, rest, and remove unnecessary clothing, including shoes and socks. Cool the body with cold compresses and/or wash the head, face and neck with cold water. If left untreated, heat stroke can result.
  • Heat stroke is life-threatening. It occurs when the body is unable to control its temperature. The body temperature can rise rapidly, and its sweating mechanism fails, and the body cannot cool down. When heat stroke occurs, the body temperature can rise to 106 degrees or higher within 10 to 15 minutes. Call 911 for emergency medical care. Heat stroke can cause death or permanent disability if emergency treatment is not given.
  • Heat stroke symptoms include red skin that is hot to the touch, changes in consciousness, confusion, altered mental status, and slurred speech. Other signs include rapid, weak pulse and rapid, shallow breathing. The body temperature may rise dramatically, and the skin may feel dry. Move someone experiencing heat stroke to a cool place and seek emergency medical assistance.

Heat-related deaths and illnesses are preventable. Despite this fact, more than 600 people in the United States are killed by extreme heat every year.
