The National Weather Service has announced that Cook County will be under an Extreme Heat Watch starting at 10 a.m. on Saturday morning, lasting until midnight on Tuesday.

For some joggers at DuSable Harbor, it means having to wake up a little earlier to beat the heat.

“Heading out early before the heat sets in is wonderful. Like starting a run at 7 a.m., it feels fantastic. The lake is amazing, and the breeze is refreshing. Being near the water is really helpful,” shared runner Kenzie.

Pet owners say they will be keeping a closer eye on their dogs, especially when they are taking them on a walk.

“I usually notice my dog is overheating when his tongue sticks out to the side. That’s what I learned online, so I bring him indoors immediately when it happens. When we have a picnic, we use a cooling pad for him to lie on,” explained dog owner Nikita.

The heat could pose challenges for places like Weiss Memorial Hospital.

Their air conditioning system is shut down, forcing all their patients to be moved, and it could be weeks until it is fixed.

With dangerous heat expected, the Red Cross is sharing how to stay safe and what signs you should look out for if you suspect heat exhaustion.

“That’s going to be if you’re feeling maybe a little bit dizzy, if your hands are clammy, if your temperature starts to rise. In that scenario, again get out of the heat. Get into a cool place, take off any extra clothing you can, put some damp paper towels or towels on you,” said Red Cross Communications Manager Mara Thompson.

Chicago’s beaches and pools will be packed this weekend as people rush to beat the heat.

And for those looking for more ways to stay cool, the Chicago Park District will be opening its 50 outdoor pools seven days a week starting Saturday.

Despite the nationwide lifeguard shortage, the district says they received 55% more applications this year compared to last year, and they are fully staffed for the season.
