Extreme Weather-Heat

The heat index is a measurement that combines the effects of heat and humidity. It tells how hot it really feels when the effects of humidity are added to high temperatures. When heat and humidity combine to reduce the amount of evaporation of sweat from the body, outdoor exercise becomes dangerous even for those in good shape.

In the event of extreme heat, you should take the following precautions:

  • Stay indoors as much as possible.
  • Turn on the air-conditioner or fan.
  • DO NOT leave children or pets in vehicles.
  • Drink plenty of water.
  • Wear light-colored, lightweight and loose-fitting clothes.
  • Apply sunscreen at least 20 minutes before going outside. SPF 15-30 is best.
  • Limit exposure to the sun, especially between 10 AM and 3 PM when it is strongest
  • Watch for symptoms of heat cramps, heat exhaustion and heat stroke.


Hurricanes are violently rotating windstorms, usually including heavy rains and winds of 74 miles per hour or higher. Hurricanes can cause flash flooding, downed trees, downed power lines, power outages and massive amount of debris on roads. The peak months for hurricanes are August and September, however, hurricane season extends from June 1 to November 30.

A hurricane WATCH means that a hurricane is possible within 36 hours.

  • Stay inside if you do not evacuate.
  • Move to a small room, closet or hallway.
  • Go to the first or second floor if you're in a multi-story building.
  • Avoid using elevators.
  • DO NOT walk or drive through moving water and find shelter immediately.
