The tropics are quiet
Posted by: Dr. Jeff Masters, 13:11 GMT le 06 septembre 2009 +3
Considering that this is historically the peak week of the Atlantic hurricane season, the tropics are quiet. There is an area of disturbed weather in the middle Atlantic (95L) that NHC has been mentioning in their Tropical Weather Outlook the past day, but this disturbance is entering a region of high wind shear and is not a threat to develop.

A strong tropical wave with plenty of rotation is emerging off the coast of Africa this morning, and this wave is a good candidate to show some development this week as it heads west-northwest over the Atlantic. The wave is under about 15 knots of wind shear, and is being developed by several models, including the GFS and ECMWF. However, the models show that this new wave will be pulled northwestward by a strong trough of low pressure this week, and it appears unlikely that the wave will make the long crossing of the Atlantic necessary to threaten any land areas. Another wave with plenty of spin will emerge from the coast of Africa two days from now, and will also have a chance to develop.


Figure 1. Morning satellite image of 95L and a new tropical wave with potential to develop, emerging from the coast of Africa.

An area of concentrated thunderstorms has developed off the North Carolina coast in association with the remains of an old cold front. This system is under about 20 - 30 knots of shear, and is not tropical. However, it will bring heavy rain just offshore of North Carolina's Outer Banks today as it slides north-northeastward along the coast.

I'll have an update Monday.

Patrap, that is so cool! thanks


Yeah,..I remember Apollo 12 well. A Perfect Landing near the edge of Surveyor Crater.

So sad they Burned out the Color TV camera while setting it up..we wouldnt have TV from the Surface of the Moon till Apollo 14.
As well..13 didnt Land.

Apollo 12 was also very Lucky as they Launched thru a FLa T-storm and the ROcket Plume made a conduit for a Strike Leader and "Boom",..Apollo 12 Got Hit by Lightening 30 secs Post Launch,Lost all their NAv and Displays and was a real Pucker Moment for the Crew.

Who Luckily were able to quickly Re-configure the Conn.

Good early Labor Day morning everyone! The tropics may be getting pretty interesting soon both in the Gulf of Mexico and Central Atlantic as we could have two different systems to track sometime within the next 72 hours. I will have much more sometime late this morning or this afternoon when I update my website again.

Quoting StormW:


I have to look at other things, but just based on the 12Z run on the steering forcast layers, which becomes valid for 00Z (4 hours ago), would you believe I look for model guidance to shift left, and I'm on the middle to southern model guidance? Based on just the steering layers forecast (which I would want to see more runs), they have 96L near 20-21N, 35-36W in 5 days, with the ridge building back.

Oh brother. We should've learned from Erika nothing goes as planned. Lol. Thanks Storm.

infact is it makes it to 40W and under 25N I would be surprised.... only thing really to watch would be home grown in the Keys or GOM over the next 2-10 days...@ least home threatening...

Making some math the models have it at 37w in 72hrs the Low is located at 20W thats 1,700 miles in 72 so 96L should move very quikly at about 25mph to make it to that point at 72hrs.

Do I am correct Storm W?

Rare View from the Launch Umbilical Tower Deck.

Super Slow Motion.
Notice the Large chunks of Ice falling from the Cold frosted Upper Stages of the Saturn 5.

November 14, 1969 carrying the Apollo 12 mission, seen from the LUT deck in slow motion.

The Video also shows the Pad pummeled by 7.5 million lbs of Thrust.

I'm in Utah. It's been 22 years since I was in college, so I'm taking some refresher courses at a community college before transferring back to BYU, then planning on UofU for my PhD in archaeology.

Wow. Nice perspective on that video Pat. We had a ball crawling all over the space stuff in the Smithsonian when I was a kid. I was telling a friend of mine all about it once. She just looked at me like big deal. Sigh. I forgot she was born after men had walked on the moon. Lol. It was a very big deal back then. Thanks for the memory. :)

00Z GFS develops 4 systems in the Atlantic in the next 9 days.

storm 1 is 96L and it appears storm #s 1,3 and 4 go out to sea

but storm #2 slips through the cracks and the GFS has it making landfall in the islands in 9 days.

im 27 and starting a 2nd b.a. in computer engineering w/an associates in meteorology for now... some people think that college is just to get a degree and go on with life, i think you can learn and study while you construct your material life also... to me learning at that level is not limited to the 18-21year old standard... obviously I have to think that to keep my esteem up high :D

especially if i plan to pursue postgraduate afterwards, which is my inclination

00Z GFS now develop another TC behing 96L and have it making into the NE caribbean 300hrs from now. I know is a long long shot but this maybe the one thats finally make some noise close to George aniversary here in the islands sept 19 to 22.
