A heatwave has left US midwest states confronting what may be some of the most sweltering days the region has seen this summer, with 55 million people included in alerts over the conditions.
A late-season high-pressure system over cities such as Chicago; Des Moines, Iowa; and Topeka, Kansas, has left them experiencing rare “extreme heat” for a long period of time, “with little to no overnight relief”, according to the National Weather Service.
States in the region have set up several public cooling centers in preparation for the dangerous heat.
An air quality alert is in effect in states including Iowa, Illinois, Kentucky, Missouri, Ohio and Tennessee, where heat indices are forecast to reach 105F (40.5C) to 115F (46.1C). Experts recommended residents to limit prolonged outdoor activity, especially those with chronic respiratory illnesses.
