96L weakens; political storm at NHC
Posted by: Dr. Jeff Masters, 1:13 PM GMT on July 04, 2007 +2
A tropical wave in the mid-Atlantic, near 10N 43W, has lost most of its heavy thunderstorm activity, but could still make a comeback and become a tropical depression by Friday. This system has been labeled "96L" by the NHC. The wave has a small closed circulation, as seen on both visible satellite loops and last night's 4:57pm EDT QuikSCAT pass. Winds from QuikSCAT were as high as 25 mph. This morning's QuikSCAT pass missed the storm. Wind shear is about 10 knots, and is forecast to fluctuate between 5 and 15 knots in the region over the next two days. By Friday, as the system approaches the Lesser Antilles Islands, the GFS model is predicting that wind shear will rise to 20-30 knots, which should tear the system apart. Dry air to the north is limiting the thunderstorm activity of 96L. The Saharan Air Layer (SAL) lies just 50 miles north of the storm's center of circulation, as seen in water vapor satellite loops. None of the reliable computer models develop the system into a tropical depression. Climatologically, formation of a tropical depression in this region of the Atlantic this time of year is quite rare, and I don't think 96L will develop.

In the Pacific, we broke a long spell of over a month without a tropical cyclone, with the formation of Tropical Storm 03W. The cyclone is expected to hit southern China as a weak tropical storm Friday.

Storm at NHC
Those of you who follow Margie Kieper's View From the Surface blog know that a major political battle is occurring at NHC. Last night, the Miami Herald broke the story that several senior Hurricane Specialists at NHC are now openly calling for NHC chief Bill Proenza's ouster. Margie and I have been quietly gathering information on this brewing story over the past few months, but have not posted anything due to the sensitive nature of the matter. Now that the story has been broken, we can tell you what we know. I will lay out the full details in my next blog, which I plan to post by 1pm EDT today.

Well, I see we are in "will it live/will it not live" mode today....

Hey, at least it is something to watch.

hey all,

Anyone have a good readup on diurnal min and max phases as well as nocturnal related to tropical cyclones? Cant seem to google the right literature.

Happy 4th to everyone. I don't have much hope for 96L doing anything. Atleast there is something to look at.
I agree with JP on the politics point. I am sick of it. No middle, just extremes. I hate both sides.

It is a political position, what do you expect? I mean the NHC Director is all over the TV when something threatens and even when nothing is out, he is addressing conferences etc.....it is like Condi Rice deciding one day to blast the State department for all the weakenesses....he should of known better before he went down the road he did.....did he really think nothing would happen? He will be gone before Sept.

Adrian,
I don't know Mr.Proenza personally nor the NHC Forecasters but this is not the time to squabble at each other wait til November for that, you need to work as a team to prepare and save lives, the NHC forecasters who are bickering should be ashamed of themselves, it is their job to be confidential about their feelings and wait. Their focus should be on 96L and the tropics not ousting their Director, there is a time and place for everything and its not now. If I was working there and a reporter asked me about the situation no matter how bad I would say " This is not the time and place for this discussion my duties are to serve the American public in tracking and preparing for this Hurricane season."

Just my take

JP,
Hypothetical situation what happens if we get a major Hurricane in the next two weeks threatening the U.S.? Will the gov't allow Mr.Proenza on tv or mute him?

Weather-related?

A 250lb World War II bomb has washed up on the shore of Crescent Beach, Florida. This is in the Northeast coast area, found this morning by a lady walking her dog. Navy explosives/ordinance team on site.

Well, we HAVE been having some heavy surf...kinda freaky.

he did not go through the proper channels, he should of known better, it is not like he is a rookie....it is one thing to point out something, it is another to basically trash your boss(NOAA)....in the real world, you would be fired the next day. I have no sympathy for the man....he made his bed, now he has to sleep in it...his own staff wants him gone.

jp, he will be out before the peak of the season.....people arent use to his face, so it will not be a loss, they will probably get one of the chicks on TWC as interm Director until after the season....lol

Hello

This is my first post and I look forward to haveing great discussions with you all.

I just wanted to say that I agree with JP's comments on Bill I think its about time someone speaks up and tells it like it is.

Kristopher,

it looks like 96L has gone thru a cemetery of dry air. the dry air was mainly at the mid levels comparable to the relatively moist upper levels. now with the forecast for wind shear to increase near the island chain. it is almost certain that 96L has met it's demise

220. nash28 4:36 PM GMT on July 04, 2007    
Yep.. Update is it is croaking and basically about to die.

WV imagery shows that the dry air has proven to be too much for this little system.

Does anyone see areas of interest that need to be watched for development in the near future or possibly several days out?

It would be tough for anyone to replace Max, but especially for a manager from outside the center who was not an experienced hurricane forecaster. These guys were used to "one of their own" managing the center and are reacting poorly to Washington going outside to name a replacement. Been there, done that. Bill needed to carefully earn his membership on their team while encouraging the input of the group of very experienced "individual contributors." In other words, "hang back while they get to know him." It didn't happen and now may be beyond repair. This problem would occur as long as they didn't name an existing forecaster as the new chief, which they didn't do for some reason that we may never know. Too bad...now we all have a problem.
226. stoormfury 4:44 PM GMT on July 04, 2007    
yes some models are suggesting that o low may move out of Africa on the weekend and track weatward across the atlantic towards the islands next week. the models are even suggesting that it could be Chantal. we just have to wait and see

well I am not writing it off yet, as long as it has a tight circulation new convection can pop up at any time.

Yeah Taz, I do. Can't make lemonade out of lemons that aren't there. Don't worry. We'll have Chantal sometime this month.

all the wish-casting going on last night looks pretty bad right now, although I'm sure it happens all the time....

I have seen lows in much worse shape then this come back from the dead, not saying it will we will just have to see

jp is right. The winds field is looking good though. Its currently going through the dinural min phase so convection associated with the system will be relatively light. I give this thing one more dinural max phase before i give up on it.

notice the outflow/windfield. that to show how much moisture the system can hold.

i'll use this pciture to show you the moisture at the surface in relation to the wind field.

Mayfield was and IS STILL a good man. How anyone can have a problem with him is beyond me.

Not going to get in a pissing political match about it either. Politics and this blog need to remain seperate.

TSR on the update today lowers there numbers a bit but still indicates an above average season looks likely.

Blame the war in Iraq for the problems at the hurricane center. I work as an Wx observer at Miami International. There has been word coming down for the last year or so that the government wants to make the tower people take observations and phase out the observer program. The talk is that this phase out would first affect c and b stations first. There is no word yet on A stations like Miami. Ft Lauderdale is a level b airport for the wx station there. Couple this talk with the aging quick scat, the fact that they are scaling down flights into hurricanes, and the fact that Noaa won't allow our satellites to study global warming anymore, should tell you all you need to know about where we stand. Our government is out of money and we are low hanging fruit. Our stations contract is awarded again in August with a take over date of Oct 1. Whether or no we will still have a job or whether or not the government will actually phase us out remains to be seen, but I can tell you that everyone in the observing field is very worried.
