Watch for signs of heat illness
Being outside for long periods during such high temperatures may cause heat illness, according to the NWS.

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 up on relatives and neighbors.
