Hopefully firefighters will not have to spend much time battling fires in the areas where Excessive Heat Warnings and Heat Advisories have been issued by the National Weather Service.
On Sunday, July 21 most of the areas identified on the map will experience heat indexes or actual temperatures around 105 or 110 degrees.
Here is a typical passage in the NWS forecasts for the affected areas:
IMPACTS…THE DANGEROUS HEAT AND HUMIDITY COULD QUICKLY CAUSE HEAT STRESS OR HEAT STROKE IF PRECAUTIONS ARE NOT TAKEN. THE VERY YOUNG, THE ELDERLY, THOSE WITHOUT AIR CONDITIONING, AND THOSE PARTICIPATING IN STRENUOUS OUTDOOR ACTIVITIES ARE THE MOST SUSCEPTIBLE. ALSO, CAR INTERIORS CAN REACH LETHAL TEMPERATURES IN A MATTER OF MINUTES.
