A heat advisory is in effect all around the Chicago area Monday. Highs are expected to be in the mid 90s, but it could feel as hot as 110 degrees. Gino Izzi, with the National Weather Service, said there’s a chance of rain Monday, but it’s not going to be the worst of the heat this week.

“Looks like we’ll get a little bit of a reprieve tomorrow especially near the lake. We’ll see winds turn off the lake and we’ll probably see highs only in the upper 80s to around 90,” Izzi said. “And then after that, the heat rebuilds on Wednesday and Thursday and it looks like the most intense heat of this week will be on Wednesday and Thursday.”

Izzi said if the heat index reaches 105 degrees,  it would be the first time it’s been that hot in Chicago since August 2, 2006.

Meanwhile, Chicago safety officials are warning residents not to open fire hydrants to cool off.

Gary Schenkel heads Chicago’s Office of Emergency Management and Communications.

“Please do not open the fire hydrants. It has a dramatic and direct impact on water pressure and the fire department needs that water pressure to fight fires,” Schenkel said.

Safety officials say drink lots of water and stay in air conditioning to keep cool.
