CHICAGO (STMW) – Chicago has seen an “unusually large number” of days with 90-degree weather so far this year, the National Weather Service said in a statement issued Sunday.

“Through June 30, there has never been a year in Chicago that has seen more 90 degree days to date than this summer,” the weather service said.

So far this year, there have officially been 17 days with temperatures above 90 degrees, the weather service said, adding that this year is currently tied with 1954 and 1977 for the number of days with 90-degree days through the end of June.

The weather service said that while this season has been particularly warm, it should not be seen as an “accurate predictor” for how hot the rest of the summer will be.

On Sunday, city officials urged Chicagoans to take precautions as temperatures are expected to continue hovering in the 90s this week.

Since Wednesday, the city’s 911 center has received almost 80 heat-related calls, and the Chicago Fire Department has made 72 heat-related transports, city officials said. The city’s Department of Family and Support Services has made 81 well-being checks, and cooling center throughout the city receive 181 visits, officials said.

Gary Schenkel, the head of the city’s Office of Emergency Management and Communications, said city residents should take the warm temperatures seriously.

“It is important to treat extreme heat temperatures as you would any other emergency,” Schenkel said. “Taking the necessary precautions can prevent heat-related emergencies and ensure safety while enjoying summer activities.”
