Millions of Americans from the West Coast to Florida are under either Excessive Heat Warnings or Heat Advisories as temperatures soar. Heat alerts are likely to expand as the heat builds across the U.S.
Dangerous heat wave sizzles much of US
Record and near record heat is taking hold from coast to coast. By Thursday, over 260 million people will be sweating out above average temperatures.
Buckle up, America. Most of the country will experience the hottest week of the summer as the dangerously hot temperatures baking parts of the South and West for weeks begin to expand to the East Coast, with more than 260 million people from coast-to-coast seeing above-average heat.
According to the FOX Forecast Center, this will be the hottest week of the summer after comparing conditions to the previous two months, as a shifting upper air pattern will plunge the East Coast into dangerous heat and humidity later in the week.
Wednesday and Thursday will be among the peak heat days with about 75% of the nation's population experiencing warmer than average temperatures. Only the Pacific Northwest and parts of the northern Rockies escape the intense heat.

Temperatures into the 90s will stretch from the Southwest through the southern Plains, Midwest, Southeast, mid-Atlantic and Northeast by Thursday.
But while temperatures will be hot, the FOX Forecast Center doesn’t expect many high temperature records to fall.
Where are the heat alerts in place?

Millions of Americans from the West Coast to Florida are under either Excessive Heat Warnings or Heat Advisories as temperatures soar.
Heat Advisories are much more expansive and encompass areas from California and the Southwest to the Plains. South Florida is also still under Heat Advisory. The Sunshine State has had those alerts in place for more than 20 straight days.
"It’s important to remind people that, you know, Florida, it does get hot," FOX Weather meteorologist Jason Frazer said. "It’s just that we’ve been historically seeing temperatures anywhere between 10 to about 15 degrees above where they should be for this time of year."
Heat alerts are likely to expand as the heat builds across the U.S. this week.

With temperatures rising, taking the proper precautions to stay safe is important.
The extreme heat has claimed several lives so far this summer, including at least two people inside Death Valley National Park in California. Last week, a 10-month-old was left alone in a hot car in Florida and died. Several people have also died in Texas and Arizona since June due to the extreme heat.
