What is a heat wave?
According to meteorologist Jim O’Brien, a heat wave is classified as at least four straight days of 90-degree temperatures.
Temperatures on Tuesday and Wednesday may break records that go all the way back to the 1950s.
The National Weather Service says hot temperatures and high humidity could cause heat-related illnesses to occur during a heat wave.
Staying safe during the heat
You’re advised to drink plenty of fluids, stay in air-conditioned rooms, limit time outdoors, and check up on relatives and neighbors. Also, never leave pets or children unattended in a vehicle.
If you do have to spend time outdoors, then try to schedule any strenuous activity to the early morning or evening. Wear loose-fitting and lightweight clothing and take frequent breaks.
If you find yourself overcome by heat, move to a cool and shaded location immediately. If you fear you may be suffering from heat stroke, call 911.
