96L weakens; political storm at NHC

By: Dr. Jeff Masters , 1:13 PM GMT on July 04, 2007

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.

Proenza came in and worked to make things better for the public. He did what many of us nonpoliticians always say we would do; cut out the politics and get something done as a public servant. By pointing out that NOAA is spending money on the proverbial $500 toilet seat and not paying attention to the true needs of the service he has painted himself in the corner. His staff isn't behind him for obvious reasons; go with your boss or the 400lb elephant against him.

If someone says that the system was decoupled, does that means that it was a TD, TS or H?

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.

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

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.

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

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.

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

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

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.

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.

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

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.

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.

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.

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?
