AccuWeather Long Range Forecaster Paul Pastelok said lower rainfall early in fall will likely keep temperatures above average. Winter appears to be a wetter season for the area, particularly due to El Niño.
Watch for signs of heat illness
Being outside for long periods during such high temperatures may cause heat illness.
Some of the first signs of heat illness are heavy sweating and muscle cramps. Additional symptoms of nausea, dizziness, headache or vomiting could indicate heat exhaustion. The NWS advises moving into a cooler environment, taking sips of water and applying cool, wet towels.
If symptoms prolong for more than an hour, seek medical attention. Worsening symptoms of throbbing headache, confusion, slurred speech, body temperature above 103 degrees, fainting or loss of consciousness are signs of heat stroke. Call 911 or get to a hospital immediately, as delayed action could be fatal, according to the NWS.
The NWS advises precautionary actions to avoid dangerous signs of heat-related illnesses, such as drinking plenty of fluids, staying in an air-conditioned room, staying out of the sun and checking on relatives and neighbors. Heat is the No. 1 weather-related cause of death in the U.S.
