The village is asking residents to keep an eye on each other during an excessive heat wave that is expected to linger through Sunday.

Forest Parkers received a robocall today from the village that warned of “hazardous heat indexes.” The message also nudged residents “to make a special effort to check on your neighbors, especially if they are senior citizens, or people with special needs who live alone.” Mayor Anthony Calderone also noted that the village is placing calls to senior citizens to check on their well-being.

“Everyone seems to be okay,” he said.

Today’s temperatures have remained in the 90s, although the afternoon’s heat index was between 106 and 114 degrees in Chicagoland, according to the Chicago Tribune’s Chicago Weather Center. Temperatures will not dip below the 90s until next Monday, the Tribune’s seven-day forecast noted.

What’s more, the heat wave is currently affecting the Midwest, the Southern and Central Plains, and parts of the Northeast, according to the National Weather Service.¬†

The village also advised the public to contact the police department for information on cooling centers; that number is 708 366 2425.

Calderone said that as long as power stays on, things should run smoothly.

“Let’s keep our fingers crossed,” he said.
