00:00Alex, we're breaking down a couple of areas in the tropics right now.

00:03Yeah, watching two areas, one in the western Caribbean and then one tropical wave way out

00:08in the Atlantic right now.

00:10But I have some good news, the one in the western Caribbean right now, a couple of days

00:14ago we were concerned that there was a track that could potentially take that feature a

00:17little further north.

00:18It does look like that's going to go west into Mexico, the feature that's circled at

00:22the bottom left of your screen there.

00:24So good news there is that it looks like it should stay away from the U.S.

00:27The other feature way out in the Atlantic right there, that's a tropical wave heading

00:31west and we saw that Puerto Rico cam.

00:33Things could look a little bit different as we head into the weekend as that storm could

00:37bring some rain and wind.

00:39And we have a few concerns for this because this will strengthen likely into a tropical

00:43storm but everything's a little bit different there as it cuts its way across the islands.

00:47Yeah, we're going to have to watch it as it comes across.

00:50It's in a pretty hostile environment right now so I don't think any development will

00:54be occurring in the near term.

00:56However, once it approaches those islands late this week, there can be that opportunity

01:00for it to strengthen into a tropical named storm.

01:02Yeah, we'll be talking about that trying to work its way on through.

01:06So there's that area of development, tropical rainstorm.

01:08I want to get ahead to where that is and when you look at the satellite imagery, what do

01:13you see with this, at least as of recently?

01:15Yeah, I see a rainstorm that's struggling to get organized right now.

01:18The center of circulation is a little bit removed essentially from those thunderstorms

01:23and if you really want development, you have to have those thunderstorms forming right

01:27over top of the center of circulation.

01:28So it's a little bit disheveled right now.

01:30There's some wind shear, there's some dry air.

01:32So in terms of the near term, I don't really see too much development.

01:36Now, the game will change as it approaches the islands, a little bit more favorable environment.

01:41So I am concerned that the storm could get a little bit more organized and we could see

01:45a named storm in the vicinity of those islands up there.

01:49And when you talk about favorable environment, we often think of the water temperature.

01:53We know that's really not a challenge.

01:54So what kind of ingredients are we looking at?

01:56Yeah, it's going to be the wind shear.

01:58Again, right now it's in an area where there's pretty high wind shear, but once it gets near

02:02those islands there, the wind shear is going to relax.

02:04And so that could give the storm a narrow window of time to potentially develop into

02:08a tropical storm.

02:09So we're going to have to watch this very, very carefully.

02:11It looks like rain is going to be probably the primary factor from this storm.

02:16There's a lot of very high mountains there, Puerto Rico, Hispaniola, mountaintops of 7,000,

02:218,000, 9,000 feet.

02:22And so it's going to be like a sponge.

02:23It's really going to squeeze out a lot of that rainfall.

02:26So I am concerned, regardless of how organized it gets, that there could be some mudslides

02:30and landslides in the higher terrain.

02:32And obviously differences, too, between those countries of how their infrastructure is organized

02:36there on Hispaniola.

02:38All things we'll be watching.

02:40AccuWeather lead hurricane expert, Alexis Silva, thank you so much for joining us.
