Interesting that the models take it right next to where Rina is forecast to be in 120hrs, near western Cuba. Perhaps it will be absorbed by Rina?

This afternoon discussion of 97L by Dr Jeff Masters.

97L approaching ABC islands
A broad region of low pressure approaching the ABC islands of Aruba, Bonaire, and Curacao (Invest 97L), is moving west-northwest at 10 mph. Heavy thunderstorm activity has increased today, but the activity is not organized into spiral bands, as is apparent from Curacao radar. 97L is surrounded by a large region of dry air, and this dry air will retard development. 97L is under low wind shear less than 10 knots, and this shear is expected to remain low through Thursday. By the time 97L reaches the region between Jamaica and Nicaragua in the Central Caribbean on Thursday or Friday, the storm should find a moister environment, and could develop into a tropical depression. However, none of the reliable models are predicting that 97L will develop. NHC is giving 97L just a 10% chance of developing into a tropical depression by Wednesday. I put the odds higher, at 20%.

That wouldn't surprise me in the least. 97L seems to be moving towards her fairly rapidly. The only question is will it be able to develop by then?

Models show it plowing into where Rina is...so it might just be murdered by her

It will be very interesting to see what interaction may occur between Rina and maybe Sean?

Good question. My take is that as the 11 PM Rina advisory products went out,they did the STWO to release them at the same time,and the system has been organizing at a steady pace tonight,but there may be other reasons.

Looks to me that Sean is about to be born soon. This entity is organizing quite well now. Interesting days ahead for all interests in the Caribbean with the progression of this system and with Rina.

A negative factor for this system,whatever it becomes,will be how the outflow from Rina affects it.
