Live from ABC News headquarters in New York City. This is Good Morning America. We're going to begin with the weather threats right now. Ginger's tracking a lot this morning, including dangerous heat for millions. But first, Ginger, you're tracking Tropical Storm Aaron, threatening to become the first major hurricane of the season. Yes, we've been watching this one for days. And now Tropical Storm Aaron is about 1,400 miles east of the Virgin Islands.

So it's still really far from the Caribbean, but in the next 36 to 48 hours, we should

have our first hurricane way out in the Atlantic.

As it turns to the north, it becomes a major hurricane.

So passing north of Puerto Rico, we still think there could be high surf and rip current

risks there.

But as it hugs that Bermuda high, the closer it gets to Bermuda, the farther it is from the East Coast. We want that front to kind of squeeze it between and nobody gets hit. That would be ideal, but we're still more than a week away from that happening. So we'll be watching carefully. There is plenty of fuel out there, four to five degrees warmer than average in the waters that that will go into.

I can assure you that if you have plans on the East Coast next week, either way, even with the spaghetti models this far away,

hundreds of miles from the coast, you'll see those waters churning and the rip current risk quite high.

Let's talk about the heat then, the other big headlines.

So from Reno, Nevada, where we've got heat

advisories to Las Vegas and Phoenix in extreme heat warnings, over to Monroe, Louisiana, Jacksonville,

Florida, up to New Hampshire, like Manchester and even Burlington. There are heat advisories in place.

So the heat will be a little above average and to the point where it can be dangerous if you're

exposed for a long time

in a place like Shreveport where it'll feel like 110 or up to Caribou where 95 is possible again today.

And that's cumulative. They had a couple of days breaking records up in parts of New England.
