AccuWeather's Alex DaSilva and Bernie Rayno monitor possible tropical development brewing in the Atlantic as we move closer towards the peak of hurricane season in September.

00:00It feels like I've been in hibernation the last couple of weeks. Not a whole lot of activity at
00:04all, so it's good to be back, but it looks like things are really going to be ramping up here
00:08as we head towards the statistical peak of the hurricane season, which is September 10th. You
00:12can see that graph there. It's like you're going up a roller coaster. Up, up, up, up, up,
00:16all the way up until September 10th, and then it's coming down from there. But it looks like
00:19things are really going to be ramping up here. All right, let's take the first system we've been
00:24talking about this all week, an area of showers and thunderstorms now around 40 degrees west.
00:28One thing I've noticed, Alex, is that on the infrared satellite picture, you've seen
00:32yellows, oranges, and reds for a pretty long period of time, and that tells us that this
00:38tropical wave, at the very least, is holding its own. It certainly is, and that's kind of
00:42been the problem for much of the year here, is these tropical waves have been actually pretty
00:46robust, but they roll off of Africa, and then they hit that Saharan dust that we've been talking
00:50about for weeks and weeks, and they just fall apart. So they really haven't been able to make
00:54much headway or develop across the Atlantic as they've come west. Now, take a look at this,
00:59Alex. Maybe some dry air along the northern periphery, but it has a river or a little area
01:06off to the west where there's not much dry air. You see blue and white, and that means
01:11there's enough moisture, at the very least, to keep this system, let's say, viable. It certainly
01:16does, and if you looked at this map a few weeks ago, almost the entire map would have been orange
01:21or red, but now we're starting to see that dry air starting to wane as we head towards the peak
01:25of the hurricane season. More tropical waves are starting to come off of Africa, and I think we
01:29have to watch each and every one of these, including this first one, for development here
01:34within the next couple of days. There's the wind shear product. There is some dark purple,
01:38southern edge of that, but what I see is also a ribbon of light purple extending toward the
01:43islands and into the Caribbean. Yeah, besides the dry air, the wind shear has kind of been a
01:48problem this month as well, but it looks like that is also starting to come down, especially
01:52across what we call that main development region, which is from the Caribbean all the way out
01:56towards Africa. So you can see that ribbon of lighter purple in there, more favorable environment
02:01for the storm as it's approaching the eastern Caribbean. ACUA, the lead hurricane expert, Alex
02:07da Silva, thanks for joining us.
