If you've stepped outside, you know it's hot.

Temperatures are expected to be in the upper 90s, with afternoon heat index values from 100 to 106. This combination of high temperatures and high humidity will lead to an increased risk of heat-related stress and illness, especially in the very young, elderly, handicapped and special needs citizens, warns Office of Emergency Management Director Jeremy Holley.

Holley asks everyone to check on your relatives, neighbors and those susceptible to heat injuries. Know the signs and symptoms of heat exhaustion and heat stroke, he said, and don’t leave children or pets in your cars.

If you or someone else may be experiencing a heat-related injury, move to a cool place and call 911, Holley advises.
