Get ready for another heat wave! Monday will begin another dangerously hot three-day stretch with temperatures in the 90s and heat indices in the low 100s. Today's heat index may max out around 100, while we are expecting 102-104 Tuesday and Wednesday.

A dangerous heat wave continues across a large part of the United States, with more than 130 million people under extreme heat watches and warnings from South Dakota to Florida.

It's easy to lose your appetite when it's too hot out. But eating the right foods will help you beat the heat.

Millions of Americans are under heat alerts Monday as a heat wave brings triple-digit temperatures or heat indices to nearly half the continental United States, according to the National Weather Service—with the heat expected to impact the parts of the Southeast and the Mississippi river the hardest.

A heat advisory will be in effect for all of north Alabama until 9 p.m. Tuesday. The National Weather Service in Huntsville said the heat index could go as high as 109 across north Alabama both this afternoon and Tuesday.

Forecasters warn of 100- to 105-degree heat index values through Tuesday, with potential storms offering limited relief.

A heat advisory has been issued for Monday, Tuesday and Wednesday for heat indices forecasted to reach 100 degrees for the first half of the week.

Heat safety is about more than just the temperature. When the heat index is high, it means that our bodies also struggle to keep us cooled off.
