Wow, 2 1/2 hrs since postings and not one comment. The first CV system of the season. Of course my chances of winning the lottery are better than 93l survival. It has to face the black plague of this years MDR.

Re: ATL: INVEST 93L - Discussion
There isn't much to talk about. It's heading toward a large region of very high wind shear, so development chances will be quite low, maybe 5% or less. I'm thinking that the NHC forecasters are just looking for SOMETHING to do. Maybe it will bring a little rain to the islands of the eastern Caribbean.

Yes bring it on. You know why I want it.

It may have a better chance in about a week or so north of Puerto Rico as it heads WNW or NW as that area has had lower shear most of the year so this can't be completely discounted as of yet

It will get shredded to pieces as it nears the eastern Caribbean, no doubt about it.

If it in some form can get north of the islands this may need to be watched as even with tropical waves in El Ninos they can and probably will form closer to land

Re: ATL: INVEST 93L - Discussion
Mid level moisture is increasing.
http://tropic.ssec.wisc.edu/real-time/s ... litE5.html
Forward speed of 20 knots would likely cause it remain just a wave and outrun the upper level high as forecast.
Every now and again one of these defies the odds and makes it through a lull in the persistent TUTT.
Maybe a 1 in 8 chance of a named storm later?

Re: ATL: INVEST 93L - Discussion
I find it interesting that the NHC is saying it has a better chance of developing beyond 48 hrs once it moves into the high shear zone. Development chances look slim to none to me.

Low pressure and Tropical Wave are two separated entities. A very quiet thread and I understand why.

The shear will rip this system to pieces once it approaches or traverses across 50 degrees Longitude with the persistent TUTT presence in the Atlantic. Extremely slim chances for this system to develop.

NEVER, EVER SAY NEVER in the tropics and weather in general, and most importantly, with life itself!!

Nothing to see here other than wait and see if the drought that some of the islands are going thru is at least aliviated.
