Sally moved onshore in Alabama this morning and is now in the process of dissipating. The storm will continue to produce dangerous rainfall as it moves northeast towards North Carolina tonight and tomorrow, but otherwise there’s not much else to say from a meteorological perspective.

With that in mind, our attention shifts elsewhere in the basin where two additional tropical cyclones and three additional disturbances await their turn in the spotlight.

From left to right in this satellite image, we have 90L (far SW Gulf of Mexico), Sally (inland AL), Teddy (east of Puerto Rico), Vicky (NE of Teddy), 98L (far bottom right), and 99L (far upper right). We can immediately cross 99L and Vicky off our list of things to worry about. 99L most likely won’t develop before bringing some inclement weather to Spain and Vicky is being torn apart by Teddy’s upper-level outflow.

That leaves us with 90L, Teddy, and 98L to look at this evening.

90L is located in the southwestern Gulf of Mexico and has been producing fairly strong albeit somewhat sporadic convective activity today. The system is nearly stationary and will remain that way more or less for the next couple days. Waters in this part of the Gulf of Mexico are extremely warm, shear is low, and mid-level dry air shouldn’t pose too much of a problem.

I would expect this system to become a tropical depression or storm by this weekend. What happens after that is far less clear. At the moment, it’s something for folks in Texas and Louisiana to keep half an eye on but not much more than that.

Out in the open Atlantic roughly due east of Puerto Rico, Hurricane Teddy is ramping up quickly this evening. The storm is producing extremely intense convection and will likely become a Major Hurricane tonight.

Teddy will continue tracking northwest before bending a bit west and passing close to Bermuda as a hurricane on Monday. That would be unfortunate for the island that just got hit by Paulette, though back-to-back storms there are not unheard of. The last such occurrence was back in 2014. What happens after the storm departs Bermuda is an open question. Folks anywhere from New England to Newfoundland should be paying attention to Teddy since it’s possible the storm’s path out to see may be blocked by a ridge of high pressure.

Much farther east, just off the African Coast, we’ll find 98L which is just a few thunderstorms scattered along a trough axis at the moment.

Most model guidance is pretty bearish on the system’s future so even if it’s able to snatch another name off the list in the next couple days, it’s not something I’m concerned about in the longer run.

Much more info to come as we track these storms over the coming days.
