Triple-digit temps expected through weekend

• Officials also opened cooling centers, which include libraries and recreation centers.

Why it matters: Extremely hot temps can lead to heat stroke or heat exhaustion and put children and pets at risk.

• Stay indoors (or by the pool with an ice-cold beverage), drink plenty of water and monitor yourself and loved ones for signs of heat stroke or exhaustion.

Of note: Symptoms of heat exhaustion include excessive sweating; cool, pale and clammy skin; nausea or vomiting; muscle cramps and a rapid, weak pulse.

• Heat stroke symptoms include dry skin that's hot to the touch, hallucinations and loss of consciousness.
• If you experience these symptoms or witness someone with them, move them, cool them and call 911.
