An early-season heatwave is impacting much of the Midwest and Northeast, with temperatures soaring above 90 degrees in cities like Buffalo, Cleveland, and Grand Rapids. Buffalo and Connecticut are under heat advisories, with the Erie County Health Department and Connecticut state agencies urging residents to stay hydrated and indoors, and opening cooling centers to assist vulnerable populations. Cleveland recorded a new high of 96 degrees, surpassing previous records, and has also opened several cooling centers. In Grand Rapids, a 'code red' has been issued, and officials are emphasizing the dangers of heat-related illnesses. The heatwave is expected to peak midweek with temperatures potentially reaching up to 105 degrees in some areas, exacerbating health risks and straining local resources.
