Saved floater loop, looks like it may have become nearly stationary with some high towers noted right over the highest area of vorticity. Circulation very evident:

No doubt about it, something's kicking. Kudos to ozonepete, gatorcane, cycloneye and the others who kept an eye on this.

Thanks, EJ. :) And if you look back at our posts on Thursday and Friday we said this would have the best chance on Sunday.

This thing is exploding right now over very warm water.

IF this is ever going to do become a TD+, it had better hurry up and do it. The model consensus suggests it has no more than ~12 hours to do so before moving inland toward the west. Does anyone disagree on this timing?

We'll have to wait a few hours to see if these pressure falls are unrelated to diurnal minimum. 94L is definitely becoming better organized this afternoon, however.

ozonepete,You think land will be the main factor for this to not redevelop?

Hard to say. Most model guidance shows this tracking west-southwestward into Honduras in about 24 hours. The NHC shows this taking a west-northwest track instead, which would bring it ashore the Yucatan in 72-96 hours.

Yeah I do, Larry. It's practically stationary right now and steering winds are very light. It could hang out there for a lot longer than 12 hours before it starts moving west, especially if it drifts a little further south or east.

Yeah Luis. I still think it's doomed to go west or southwest into land at some point. And though not very likely, there is a chance it could drift eastward or southeastward and then it could hang out for days in very light steering winds.

Oh, but I should add it sure looks like it will make TS before that happens.

We are seeing signs of organization the past several hours. Water temps are around 84F where this invest is located and deep convection with high towers continues to blow up right over the area of vorticity. I am still not seeing any movement either. Look at that huge upper-high right on top (second image below). We are witnessing the power of the NW Caribbean. All this invest needed was its window of opportunity and look what is happening. That is why any kind of vorticity in the NW Caribbean this time of year needs close watching.
