Tropical wave bringing heavy rain to northern Lesser Antilles
A tropical wave near 18N, 60W is entering the northernmost Lesser Antilles Islands and is generating some disorganized heavy thunderstorm activity. This wave is under about 20 knots of wind shear, due to strong upper-level westerly winds. The strong upper-level winds are associated with the counter-clockwise flow of air around an upper-level cold-cored low pressure system a few hundred miles north of Puerto Rico. As the wave progresses west to west-northwest through Tuesday, thunderstorm activity will increase, due to interaction with the upper low. The rains from these thunderstorms will bring the threat of flooding to Puerto Rico on Monday, the Dominican Republic on Tuesday, and Haiti on Wednesday. The upper low will also bring high wind shear of 20 - 30 knots over the the wave on Monday and Tuesday. No development of the wave is likely until at least Thursday, when it will be over the eastern Bahamas and eastern Cuba. At that time, shear is expected to drop below 20 knots, and the wave has the potential to develop. However, none of the reliable computer models is calling for tropical cyclone development over the next seven days. I expect that this wave will eventually enter the Gulf of Mexico early next week. NHC is giving the wave a 10% chance of developing into a tropical depression by Tuesday.

A dip south, then NW in high temps?
Still high temps, yes.. I believe they are above normal, I think.
I'm out 4 now..
Pay per post simple as that 20 posts for $1, 100 posts for $5 ,price can vary of course, bloggers who get "+" can get free posts, I rarely post anyways but it might help get the good info out there from a blogger.
you have some big issues in the brain dept.
iam sorry
It's ok, I respect you
Umm, more heat in the atmosphere? We only had Alex, really hasn't cooled the Caribbean waters much, and the GOM continues to stay dry which creates more sunshine, more heat into the waters.
In that scenario it will aid in increasing the SSTs off Africa?
Oh and the weakening of the ridge.
StormW...PLEASE do not leave!
Now for my guess...weak trade winds?
I have told him before don't do this... He is way to sensitive. Storm seems to think being here is some sort of job he does not like. I am here to read about weather and the tropics... and wish others would follow the rules. Stay on topic...
Dude... Post the graph that shows avg. years usually have very little b4 August. I don't think everyone has seen it yet.. LOL
..a Lot of Experience is the wisdom learned from it.
Been posted by DestinJeff many times this weekend but people still assume a slow season is the right idea.. whatever. lol
Thanks to people like you, us Hispanics have such a bad reputation in this country.
As a newbie, I hope you don't leave. But I would like to point out that the strictly posting of data without explanation makes things really difficult on us newbies.
Case in point: "....and the behavior of the MJO in the past 2 months. And if it does, it may be short lived, and the MJO could jump back to the Octants in our area."
People like me go, "Huh, MJO? Octants? What is that all? I don't mean to call you out specifically. Every day, I look for meaningful posts and I could count on my hand the number of times that I get an explanation as to a map or graphic or data that is posted to go along with the said data.
So now you got ppl who just post a link to a map with no narrative, no explanation and fifty people responding, Wow! Look at all those pretty colors and numbers. A lot of us and including those that have been here for a while are left to make conclusions, often WRONG conclusions because they are left to their own devices to come up with an explanation for the data or simple maps that are posted.
And, I realize Storm that you've done a great job to explain acronyms and such on your board and you are certainly the exception and have offered us Florida natives up to your place for better learning. However, I think if the knowledgeable ones around here would take just a moment or two and explain the data or maps that they are posting, it would go a long way in having the community avoid having 50 different interpretations of the data and the poster from saying, "Why don't you look at the data?"
Maybe somebody with time on their hands could develop a simple powerpoint as to explaining the maps and data formats that are out there?
Trust me, Storm. There are several impressionable people out here that are getting several incorrect interpretatons of the data and maps from other posters simply because the original poster just gives a link and no corresponding narrative.

I know, I was just kidding... What few in here don't realize is that Mother Nature is probably just winding up for the "pitch." I've said it before, IMHO come mid Sept., the naysayers in here will be screaming UNCLE!
I'm with you MH. Oh and hello everyone.
Interesting, I see it now.. Thanks :)
Nevermind.
Hi Homeless - I see the smiley faces are back... :)
Thats why I find myself going back to Storms blog and looking at his list of NAOs,SSTs,
Acronyms.
