AccuWeather Lead Hurricane Expert Alex DaSilva was live on the AccuWeather Network on Sept. 26 to discuss the latest on the tropics.

AccuWeather meteorologists are closely monitoring two tropical systems in the Atlantic that could impact the Carolinas and the broader East Coast. The proximity of these storms may cause unpredictable movement, complicating forecasts and increasing uncertainty about their eventual paths. Warm ocean waters and low wind shear are creating favorable conditions for storm development, with the potential for one system to become a tropical storm as it moves north.

Depending on how the storms interact, there is a risk of significant flooding in the Carolinas if one system stalls after making landfall. Regardless of the exact track, rough seas and dangerous rip currents are expected along the East Coast, from Florida to Maine. Residents in affected areas are advised to monitor updates closely due to the potential for rapidly changing conditions.

Early-week storm risk for the Carolinas

Joining us right now is AccuWeather lead hurricane expert Alex DeSilva and of course we've been talking about Umberto, but as we head into early next week, Alex, we're going to see two storms of close proximity to each other, we think, and we do have a name for that. Storms get within about 850 miles of each other and then they can start to pull on each other or dance around each other a little bit, so it can cause some erratic movements between the two different cyclones, so this is something we're going to have to watch very carefully over the next couple of days. If we just had one storm, the forecast would be much more straightforward, but since there's two of them, there's going to be some wiggle room, I think, in the forecast over the next couple of days. It's not only the forecast that's a little murky at the current time, Alex, it's trying to figure out exactly where we have a low-level center. Right now, it's more of a broad circulation, but not having a low-level circulation is problematic as well. Yeah, it certainly is. We're thinking that it's somewhere right now located just off the eastern tip of Cuba, but look at all the convection to the south and east of where we think that low-level center might be trying to form. That could be problematic here as it could try to drag that low-level center a little more south or west, so we're going to have to watch these trends here over the next 12 to 24 hours to see exactly where this low-level center forms. If it keeps moving west, we could have whole different problems if it tries to get into the northern Caribbean here, so we're just going to have to watch it. We still do expect this to pull to the north, but until a low-level center actually forms, there still can be a little bit of a discrepancy on where this could end up. Now, of course, the farther west it gets, the more problematic perhaps for Florida instead of the Carolinas, so that's something, and I know the hurricane center is flying a plane in right now. Regardless of the exact location, whether it's the northwest Caribbean or in the Bahamas, waters are just exceptionally warm. Yeah, indeed they are. We look for about 80 degrees Fahrenheit. You have some 86s, maybe even some 87s in some areas, so plenty, plenty, plenty of energy to work with with this storm, and look at the area that it's moving into, an environment of lower wind shear, so that is going to be problematic, I do believe. Once it's able to pull away from the islands, which I think are preventing any development right now, it's going to get into an environment ripe for development, and then we could see a tropical storm on our hands, and then the big question is, does it stay closer to the coast and then drive inland across the Carolinas, or does Humberto to the east have an influence and pull it a little bit further offshore? Well, I've been showing this all morning, so we've been saying all along, by Sunday it's off the Florida coast. Okay, as you mentioned, if we didn't have Humberto, this would be pretty straightforward. If we put your hand and rock out Humberto, the high near Bermuda and the upper low across the Appalachians would drive this into the Carolinas, and historical tracks show that it would most likely be between Charleston and let's say Cape Lookout, North Carolina. But you were talking about the Fuji War Effect, that's one way to look at it. The other way is just a good old tug of war between the upper low and Humberto. Yeah, it's whichever one's going to win out, and I think if our probably tropical storm here is able to move a little quicker, then the upper low probably wins out and then the storm is able to come inland. However, if the storm takes a little bit longer to get organized near Cuba, if it meanders around down there, that allows Humberto to come in a little bit closer, and then it gets within that 850 miles, and then it's able to pull the storm more offshore. So we could be dealing with a variety of situations where potentially the storm could come inland, stall, and then back out back over the ocean. So anyone from Florida up to the Carolinas needs to watch this very carefully. The potential for a big-time flooding event is on the table here across the Carolinas if we indeed do get that stall. So we're going to watch out for a potential landfall. Could happen anywhere between Monday night into Wednesday. Again, a lot of that is depending on the exact timing and how quickly that rainstorm is able to come to the north. And then like I said, we're watching for potentially life-threatening flooding if that storm is able to come inland, maybe stall, and then back back out over the ocean. But what we are confident in right now, highly, highly confident, rough seas across the entirety of the East Coast, I think starting probably Sunday into Monday, and then the beach conditions. Anybody along the East Coast next week especially needs to watch out very carefully because there's going to be rip current risks anywhere from Florida to Maine. And of course, the Outer Banks of North Carolina already reeling from two systems that caused so many problems.
