National Weather Service Issues Excessive Heat Watch for this Weekend

The National Weather Service has issued an excessive heat watch from Saturday afternoon through Saturday evening. Heat index values may rise to around 105 degrees during the afternoon hours Saturday and remain above 105 degrees until early Saturday evening.

An excessive heat watch means that a prolonged period of hot temperatures is expected. The combination of hot temperatures and high humidity can combine to create a dangerous situation in which heat illnesses are possible.

To provide the public with relief from the heat, City of Los Angeles facilities are utilized as cooling centers. A list of these facilities is available at on the banner that says Cooling Facilities to beat the heat.

These facilities include Senior Citizen Centers, Recreation and Parks facilities, and Libraries. Hours vary by facility, please check with the facility for their current hours of operation.

During periods of excessive heat there is an increased risk of unhealthy air quality, heat exhaustion, heat cramps and sunstroke. People that have sensitive health conditions should take the necessary precautions and limit outdoor activities.

Since energy use does tend to spike during periods of hot weather the Department of Water and Power offers a few ways to conserve energy during this heat wave:

  • Turn off lights when not in use.
  • Adjust thermostat to 78 degrees to reduce energy usage.
  • Limit the use of appliances during peak hours of the day—use washing machines, dishwashers, vacuum cleaners and other heavy appliances during evening hours.
  • Try to avoid cooking during peak hours of the day since it will add to the heat inside the home.
  • Ventilate your home at night by opening windows and doors to clear out the heat and allow cooler air to circulate.

During periods of excessive heat there is an increased risk of heat exhaustion, heat cramps and sunstroke. Here’s what you can do when the weather gets extremely hot:

  • 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.
  • 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. 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.
  • Protect face and head by wearing a wide-brimmed hat.
  • Check on family, seniors, friends, and neighbors who do not have air conditioning and who spend much of their time alone.
  • Never leave children or pets alone in closed vehicles.
  • Avoid strenuous work during the warmest part of the day. Use a buddy system when working in extreme heat, and take frequent breaks.

And finally, never, ever leave children, the elderly or pets in enclosed automobiles, even for a short period of time. Even if the windows are partially open, temperatures can quickly rise to life-threatening levels.
