Right up front, let me be honest: the forecast for early next week is as clear as muddy water. I wish it were simple, but the truth is the atmospheric pattern ahead is highly complex. That means there are a multitude of possible scenarios, so everyone in the Bahamas, Florida, and the Southeast U.S. need to stay updated through the weekend.
Why this forecast is so challenging:
1. INTERACTING DISTURBANCES – Both systems have a high chance of developing into a depression or storm between today and Sunday. But they may end up close enough to influence each other’s intensity and track. For example, Disturbance 1 is expected to become a tropical system today or tonight then strengthen into a hurricane this weekend. That could weaken, or even absorb, Disturbance 2. On the other hand, if they are far enough apart and eventually of similar strength, they could perform a tropical “dance,” rotating around one another. Even subtle differences in strength or position will make a big difference in where each system ultimately goes. For what it’s worth, the morning model runs show both systems developing with Disturbance 1 forming first and being more dominant, effectively pulling Disturbance 2 away from the southeast coast. I’ll need to see this trend continue and also see ensemble support to buy into that.
2. COMPLICATED STEERING CURRENTS – As if the interaction between the two systems weren’t enough, the steering flow is equally complex. The jet stream will dip south, forming a low-pressure area aloft. These “cut-off” upper-level lows are notoriously hard to predict. Models disagree widely: if it sets up near the Carolinas, both systems could be steered harmlessly out to sea. But if it forms farther west and south, Disturbance 2 could be pulled closer to the Southeast U.S. At this point, there’s no clear lean one way or the other.
BOTTOM LINE – There’s nothing you need to do right now other than stay aware. Once one or both systems organize, the forecast will come into much sharper focus. If we were to see any impacts here, the window would be Monday through Wednesday.
