Nearly 80 million people were covered by the advisories and warnings on Tuesday, and it is expected to straddle 100 degrees again on Wednesday in many cities. The heat index, which measures what the temperature feels like with heat and humidity, reached 101 degrees in New York City, 102 degrees in Boston, 108 degrees in Washington, D.C., and 100 degrees in Oklahoma City on Tuesday.

A heat wave that is fueling wildfires on the West Coast is expected to push temperatures to 115 degrees in Phoenix on Thursday, and 101 degrees in Los Angeles on Friday. There are reports of at least eight heat-related deaths in Canada and the U.S. beginning last weekend, six of them in Montreal.
