A heat wave that baked much of the central United States last week will start to move eastward with dangerously high temperatures, forecasters said Monday.

The National Weather Service told Americans to grid for another day of well above normal, near-record or even record-breaking heat from the central Plains to the Upper Midwest.

"Dangerous heat will continue to make headlines," the service said in an advisory.

The scorching blast will start to drift eastward Tuesday into the Great Lakes region with highs in the upper 90s Fahrenheit (mid 30s Celsius) which is up to 20 degrees F above normal.

Around 120 million people were under some sort of advisory last week as a heat wave burned the Upper Midwest and the Southeast. 

Yellowstone National Park, the oldest in the United States, closed down last week because of extensive flood damage as roads were washed away.

Torrential rainfall and snowmelt sent months' worth of run-off into rivers in just a couple of days. The sprawling park sits mainly in Wyoming and is home to the Old Faithful geyser.

Helicopters were used to rescue nearly 90 people.

The park said its southern section will reopen to visitors on Wednesday. Park officials say other parts will remain closed for the rest of the season.
