Almost 72 million people across the country were under warnings of extreme heat Monday morning, the National Weather Service said.

With Thursday's seasonal solstice taking place amid a weeklong heat wave expected for the East Coast and the Midwest, the summer of 2024 is coming in hot.

Extreme heat warnings were in place for Chicago, St. Louis, Indianapolis, Detroit, Cleveland, Cincinnati, Pittsburgh, Philadelphia, Boston, New York City and Albany, New York.

A moderate heat risk warning means that people are at risk for any long periods of sun exposure; a major risk warning means heat-related health impacts are likely, while an extreme heat risk warning means the effects, such as heat exhaustion and heat stroke, could be fatal.

Some 150 million people will experience temperatures above 90s degrees on Monday and for 9 million people it will be over 100, with heat alerts in place from Iowa to Maine.
