In brief: There is a lot to talk about in the Atlantic tropics this morning, but the headline remains an as-yet unformed storm that is likely to become a tropical depression near the Bahamas soon. After that there is an increasing possibility that the tropical system will approach the southeastern United States by next Monday or Tuesday.

We start with the storm most people will care about the most: an area of low pressure now moving away from Hispaniola toward the Bahamas. The system does not yet have a closed circulation, but it will encounter favorable conditions as it pulls away from the Caribbean landmasses toward the open waters of the southwestern Atlantic Ocean.

We are fairly confident about the evolution of the storm through the weekend, as it should become a depression and then probably Tropical Storm Imelda. By Monday, when we look at a broad range of traditional and AI model solutions, we see that the system should have moved to the north of the Bahamas, and be located somewhere off the southeastern coast of the United States. The map below shows the model outputs for 8 am ET on Monday morning.

After this time frame we see a pretty broad divergence in the models. A majority of the solutions, but not an overwhelming majority, bring the system toward the Carolinas by around Tuesday. However a non-trivial number of models peel the system back to the east, into the open Atlantic, due in part to some complex interactions with Hurricane Humberto. Anyone having confidence in what, precisely, will happen at this point is probably not being honest with themselves (or you).
In terms of intensity the models are not super bullish on this blowing up into a major hurricane. In fact, the majority of solutions keep the system at a tropical storm or Category 1 hurricane level. Again there is a lot of uncertainty here, so something to continue watching.
What I am reasonably confident in saying is that there is real potential here for a rainmaker in the Carolinas, and particularly North Carolina. Readers there will certainly and understandably be concerned that this could become another Hurricane Helene-like event. For now, we think that is unlikely, as the strongest rains appear to be east of areas most impacted by Helene, and the overall signal for prolonged, heavy rainfall is lower this time. For now NOAA is predicting 6 to 10 inches of rainfall for areas hardest hit, which is no picnic, but also far from reaching Helene-levels.

We are also monitoring storm surge and wind threats, which of course will be highly dependent on the track and intensity of the storm.
Hurricane Humberto
Humberto has become a hurricane, with 75 mph winds. Fortunately this storm is further out to sea than Invest 94L, because it is highly likely to blow up into a major hurricane over the next several days. The storm’s biggest threat will likely be to the small island of Bermuda.

At present Humberto has about a 40 percent chance of bringing tropical storm-force winds to Bermuda early next week, likely on Tuesday. There will also be the potential for storm surge, but my hope is that the hurricane is weakening and remains far enough west of Bermuda to spare the island more than a glancing blow. We will keep a close eye on the track over the weekend.
Gabrielle
This storm is no longer tropical, but it still managed to bring significant winds and waves to the Azores. It could also bring tropical storm-force wind gusts into Spain by Sunday, along with some much needed rains for the Iberian Peninsula.
