Extreme Heat Porterville College

excessive heat warning

Criteria for an Excessive Heat Warning is a heat index of 105 °F or greater that will last for 2 hours or more. Excessive Heat Warnings are issued by county when any location within that county is expected to reach criteria. For example: If you expected the heat index to reach 105°F in the city of Porterville, an Excessive Heat Warning would be issued for that zone.

Extreme Heat

Extreme heat is a period of high heat and humidity with temperatures above 90 degrees for at least two to three days. In extreme heat your body works extra hard to maintain a normal temperature, which can lead to death. In fact, extreme heat is responsible for the highest number of annual deaths among all weather-related hazards.

Remember:

  • Extreme heat can occur quickly and without warning.
  • Older adults, children and sick or overweight individuals are at greater risk from extreme heat.
  • Humidity increases the feeling of heat as measured by a heat index.
Safety Campaign

If you are under an extreme heat warning

  • Find air conditioning.
  • Avoid strenuous activities.
  • Wear light clothing.
  • Check on family members and neighbors.
  • Drink plenty of fluids.
  • Watch for heat cramps, heat exhaustion and heat stroke.
  • Never leave people or pets in a closed car.

Prepare Now

Find places in your community where you can get cool.

Try to keep your home cool:

  • Cover windows with drapes or shades.
  • Weather-strip doors and windows.
  • Use window reflectors such as aluminum foil-covered cardboard to reflect heat back outsid.
  • Add insulation to keep the heat out.
  • Use a powered attic ventilator, or attic fan, to regulate the heat level of a building’s attic by clearing hot air.
  • Install window air conditioners and insulate around them.
Safety Campaign
  • Never leave a child, adult, or animal alone inside a vehicle on a warm day.
  • Find places with air conditioning. Libraries, shopping malls, and community centers can provide a cool place to take a break from the heat.
  • If you’re outside, find shade. Wear a hat wide enough to protect your face. Wear loose, lightweight, light colored clothing.
  • Drink plenty of fluids to stay hydrated. If you or someone you care for is on a special diet, ask a doctor what would be best.
  • Do not use electric fans when the temperature outside is more than 95 degrees. You could increase the risk of heat-related illness. Fans create air flow and a false sense of comfort, but do not reduce body temperature.
  • Avoid high-energy activities. Check yourself, family members, and neighbors for signs of heat related illness.

Heat Stroke

  • Signs: Extremely high body temperature (above 103 degrees) indicated by an oral thermometer; red, hot, and dry skin with no sweat; rapid, strong pulse; dizziness; confusion; and unconsciousness.
  • Actions: Call 9-1-1 or get the person to a hospital immediately. Cool down with whatever methods are available until medical help arrives.
Safety Campaign

Everyone can be affected by hot weather and it is important that you take care whenever the temperatures start to rise. A heatwave over a period of days, or even a single day of extreme heat, may cause illnesses such as heat cramps, heat exhaustion, and heatstroke.

It's important to stay aware of the weather during summer, especially when there are risks of heatwaves.
