The National Weather Service has issued a wind chill warning for Chicago and the surrounding suburbs from Wednesday evening through Friday morning. Temperatures are expected to drop to 0 degrees Fahrenheit by Wednesday night, but wind chills could make it feel as cold as -30 degrees Fahrenheit. The frigid conditions could cause frostbite and hypothermia within minutes of exposure for those not properly dressed. Residents are advised to stay indoors if possible, and those who must go outside are urged to bundle up with multiple layers of clothing, including a hat, scarf, and gloves. The extreme cold is also expected to affect transportation. The Chicago Transit Authority (CTA) is urging commuters to allow for extra travel time as buses and trains may experience delays or cancellations. The Chicago Department of Transportation (CDOT) is also monitoring road conditions and is prepared to salt and plow streets as needed. Officials are concerned about the impact of the cold on vulnerable populations, including the homeless and the elderly. The city has opened warming centers where people can seek shelter from the elements. The Arctic blast is expected to be short-lived, with temperatures gradually rising over the weekend. However, residents are advised to take precautions to stay safe during the frigid conditions.
