The National Weather Service has issued a hazardous weather outlook for the Danville area. Hot conditions are expected to continue for the remainder of the week, especially Friday into the weekend. Heat index values may exceed 100 degrees.

The heat index refers to a number in degrees Fahrenheit (F) that tells how hot it feels when relative humidity is added to the air temperature. Exposure to full sunshine can increase the heat index by 15 degrees.

Tim Duffer, deputy emergency management coordinator for the Danville Fire Department, said the heat index will be in extreme caution to danger range.

“If you have any heat-related illness, then please take steps to move to a cooler place,” Duffer said. “If you need further help, then call 9-1-1. Heatstroke is a true emergency.”

Heatstroke is a serious failure of the body's heat-regulation mechanisms resulting from excessive exposure to intense heat and characterized by high fever, dry skin, collapse, and sometimes convulsions or coma

Here are more tips on that you should do when the weather is extremely hot:

  • Listen to NOAA Weather Radio for critical updates from the National Weather Service (NWS).
  • Never leave children or pets alone in closed vehicles.
  • Stay indoors as much as possible, and limit exposure to the sun.
  • Stay on the lowest floor out of the sunshine if air conditioning is not available.
  • Postpone outdoor games and activities.
  • Consider spending the warmest part of the day in public buildings such as libraries, schools, movie theaters, shopping malls, and other community facilities. Circulating air can cool the body by increasing the perspiration rate of evaporation.
  • Eat well-balanced, light, and regular meals. Avoid using salt tablets unless directed to do so by a physician.
  • Drink plenty of water; even if you do not feel thirsty. Avoid drinks with caffeine. Persons who have epilepsy or heart, kidney, or liver disease; are on fluid-restricted diets; or have a problem with fluid retention should consult a doctor before increasing liquid intake.
  • Limit intake of alcoholic beverages.
  • Dress in loose-fitting, lightweight, and light-colored clothes that cover as much skin as possible. Avoid dark colors because they absorb the sun’s rays.
  • Protect face and head by wearing a wide-brimmed hat.
  • Avoid strenuous work during the warmest part of the day. Use a buddy system when working in extreme heat, and take frequent breaks.
  • Check on family, friends, and neighbors who do not have air conditioning and who spend much of their time alone.
  • Avoid extreme temperature changes.
  • Check on your animals frequently to ensure that they are not suffering from the heat.
