NWS also advises that people who must work outside take extra care: “Take extra precautions when outside. Wear lightweight and loose-fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.”
No cooling centers were announced as of Tuesday afternoon, but local libraries are open during their regular hours.
