Atlantic Still Quiet, though Tropical Wave May Bring Wetness to Bahamas and SE U.S.
I apologize for the lack of posts since Debby’s dissipation. Summer has been busy so far for me.
The Atlantic remains quiet through the first 10 days of July, as was expected. It will continue to be this way through at least the end of the month the way things currently look. El Nino years favor a quick-firing start to the season in June, but a quick ramp-down to start the heart of summer. Our next real shot at tropical development will likely not come until August when the MJO comes back to the Atlantic and drags some upward motion out of the eastern Pacific, where they have a whole train of storms going, and moves it into the Atlantic as the African wave train strengthens.
Speaking of waves, the only somewhat interesting feature to watch right now is a very large, dry tropical wave along 45W that has no thunderstorms associated with it, but can be seen with a vigorous signature in the mid-level flow.
This wave will be moving WNW into the the region between the Bahamas, Bermuda, and the SE U.S. during the next 4-7 days, being steered towards this region by a strong Bermuda High to the north. While none of the computer models currently do anything with this wave, moisture will be becoming more abundant in the SW Atlantic as the wave moves in, and upper-level temperatures are and will continue to be colder than normal due to significant upper-level troughing over the Bahamas, which overlaying 28-29C waters can cause some instability. As a result, some convection can be expected off the SE U.S. coast that may bring some wetness to the Bahamas and the coastal SE U.S. over the weekend. Given the large size of the wave, tropical or subtropical development chances seem low for now, especially with no excitement from the computer models, but expect the atmosphere to become rather soupy in the region with at least some thunderstorm activity, perhaps a little more than currently forecasted by some of the models.
CMC 96-hour forecast:
If you couldn’t tell, I’m showing off some of the new graphics I have been developing in my spare time. The first image was a GDAS analysis of 650mb meridional wind/heights, and the 2nd was the well-known Canadian model forecast. These and more products can be found on the Analysis Tools page. I will be adding more as time goes on.
Overall, the Atlantic in general will likely remain void of significant tropical activity until August. Remember, a fast start doesn’t always mean an above-normal hurricane season. We should end up with a near normal storm count by the end of it.
We shall see what happens!

Thanks for the update. The new graphics are very easy to read and are laid out nicely. Thanks for your work.
Just a quick note – thank you for the update and nice work on the color scale for the PWAT graphic. IMO, that is the best I have ever seen as it is very intuitive.
Thank You. Your work shows and is appreacated!
Again– thanks for the quick update ! Can’t wait till the “Real” season kicks in .
Thanks for the update Levi. While I have been missing your posts … it was definitely worth the wait to see the new graphics. Thanks for making it easier for us novices to understand.
Thanks Levi.. good to get off the climate change crap on wunderground sometimes.
Living on a boat in the Florida Keys does have one challenge; Keeping informed about the tropical summer time weather. Your thorough and informative forecasts, Levi, make that task so much easier and because of Your great work, I’m sleeping a whole lot better better this time of Year.
As usual, your post is truely informative. Looking forward to more. I always open you post before any others including Mr Masters Posts. Keep up the great work
Thanks for the tips you have contributed here. Another thing I would like to cnveoy is that laptop or computer memory requirements generally rise along with other advancements in the engineering. For instance, if new generations of processor chips are introduced to the market, there is certainly usually a related increase in the size and style preferences of all computer memory along with hard drive space. This is because the software program operated simply by these processors will inevitably rise in power to make new technologies.
Why would anyone say they can’t wait for the real season?
Do you want a hurricane to hit you, or do you live in Kansas?
Nice graphics
cupcake8million Posted on congrats- your liinvg my dream since you won’t see your family/ friends for a long tie you could go cheesy- wish you were here or on the trail again or Where in the world is (your name)? Best of luck!
c172Remarkable post & Outstanding weblog! I would like to begin a blog too but I’ve no clue where to start. I have the relvnaet skills to do it (not that hard on the practical part) but I honestly feel like I’m just too lazy to post frequently That’s the matter, if you start you need to go all of the way b7
Woah! I’m really diinggg the template/theme of this site. It’s simple, yet effective. A lot of times it’s very difficult to get that perfect balance between usability and visual appeal. I must say you’ve done a awesome job with this. In addition, the blog loads very fast for me on Safari. Outstanding Blog!
Haven’t looked myself, but am wondering when MJO starts to swing this way again?
It could still be a while. The ECMWF, probably the most reliable predictor of the MJO, doesn’t show it getting into phases 8 or 1 through mid-August. The monthly forecast can be a little too slow, but we probably won’t be seeing the MJO for at least the next 2 weeks.
Let’s hope for a boring summer hurricane wise.
You have mail, BTW.
Thanks for your interesting reports as always.
@Deadwood , du coup je sais pas si je vais faire ma review du final de Lost pour moi Zach a tout dis , je pense e9galement la meame chose .Limite rien e0 aotjuer tellemernt e7a exprime bien ma pense9e .Sauf que lui il aime le 6 15 et pas moi .
Levi:
Just looking at imagery this AM and thinking we might have some “awakening” in the Atlantic Basin. Not today, not tomorrow, but looks like some hints of things to come…
Your thoughts?
I was just reading a blog and it said the SAL is going down. It also said some of the computer models are suggesting something developing off the coast of Africa. Have you been following this?
Cape Verde season is almost upon us. Expect some stronger tropical waves that could develop as we dig into August.
Makes sence why girahim watned to release the demon lord he watned him dead so he could get the triforce of power it’s mentioned in twilight princess he ends up missing but he never got sealed away cause he was originally a spirit like the master sword but when it shows the video of Minda getting struck by Zant and how he could teleport ect made sence he was in Zant and that when Gannondorf was expected to get triforce of power that he would steal it off him thats why Zant snaps his neck and Gannondorf losses the triforce so there has to be a return of girahim
When are you planning your next tidbit?
Probably Friday.
Are you doing your tidbit today?
Funny that Levi has “appeared” idle for the past couple weeks. Dude, you have to be going stir crazy with this inactivity….
BHC ought to throw one of their yellow dimes down on the chart near Guadaloupe for the fun of it. Its almost wave season.
NHC not BHC
Sigh Seriously? Why can’t they come to the east coast too? Don’t they realize that plae ticetks cost alot? And that North America is a HUGE continent? It’s bad enough I have to miss out on E3. I really wish I could go. For all those that do go, have fun! I’ll just have to buy the cd!
Another one for nomToo Much of a Good ThingWhy we need less democracy. Peter Orszag September 14, 2011 2000| 9:46 pmIn an 1814 leettr to John Taylor, John Adams wrote that e2809cthere never was a democracy yet that did not commit suicide.e2809d That may read today like an overstatement, but it is certainly true that our democracy finds itself facing a deep challenge: During my recent stint in the Obama administration as director of the Office of Management and Budget, it was clear to me that the countrye28099s political polarization was growing worsee28094harming Washingtone28099s ability to do the basic, necessary work of governing. If you need confirmation of this, look no further than the recent debt-limit debacle, which clearly showed that we are becoming two nations governed by a single Congresse28094and that paralyzing gridlock is the result.So what to do? To solve the serious problems facing our country, we need to minimize the harm from legislative inertia by relying more on automatic policies and depoliticized commissions for certain policy decisions. In other words, radical as it sounds, we need to counter the gridlock of our political institutions by making them a bit less democratic.
Thanks , I have recently been searching for info about this subject for a long time and yours is the greatest I’ve came upon till now. But, what concerning the bottom line? Are you certain about the source?|What i don’t realize is in reality how you are not actually much more neatly-preferred than you may be right now. You are very intelligent.
c117I just desire to meitnon I’m very new to blogging and site-building and certainly liked this internet weblog. Quite likely I’m going to bookmark your blog . You essentially come with superb articles. Thanks for revealing your webpage.b4
I have read several good stuff here. Certainly worth bookmarking for revisiting. I surprise how much attempt you set to make any such excellent informative site.
