A heat dome has formed over the Midwest and eastern United States, bringing dangerously high temperatures to Illinois, including Cook County.
This marks the first heatwave of the summer for the region.

Impact & Risks

The heatwave poses significant health risks, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Prolonged exposure to high temperatures and humidity can lead to heat exhaustion or heatstroke. The conditions may also strain local infrastructure, including power grids, as residents turn to air conditioning to cope with the heat.
