Transcript for Heat Wave Sweeps Across America
Brian, we want to move now to the scorching heat, the hottest temperatures of the year for much of the nation and on each coast, big surf from two different hurricanes and ginger is tracking it all. Good morning, ginger. We'll start with the dangerous heat and heat becomes dangerous when it's cumulative and has been. Yesterday St. Louis, first 100 of the season. And today the heat index, you can see, will value anywhere from 101 in Houston and St. Louis on their seventh day with an excessive heat warning. That's what happens. Now the heat dome presses east at least for a short time. New York City, Philadelphia, D.C. All looking for 90s by the midweek and it will break quickly and rough surf from Cristobal. It won't affect you unless you're getting in the water. Do look for dangerous rip currents and then we've got hurricane Marie. At closest point about 800 miles away, waves could reach 10 to even 20 feet, George. Okay, ginger, thanks very much.
