Bill Proenza gone; tropical update
Posted by: Dr. Jeff Masters, 8:35 PM GMT on July 09, 2007 +2
With hurricane season fast approaching and internal strife threatening "the effective functioning of the National Hurricane Center", as stated in a letter signed by 23 of NHC's 49 employees, NOAA did the best thing by reassigning director Bill Proenza this afternoon. Conrad Lautenbacher, the head of the National Oceanic and Atmospheric Administration, announced Proenza has been placed on leave "until further notice."

The reassignment puts NHC deputy director Ed Rappaport, 49, into the director's hot seat. I greatly respect Dr. Rappaport, who has done a great job as deputy director and is a highly skilled hurricane forecaster. Dr. Rappaport has a Ph.D. in Atmospheric Sciences from Texas Tech. He began work in 1988 at NHC, and served as one NHC's Hurricane Specialists before becoming chief of the Technical Support Branch. He is the best choice for director of NHC. He had wide support to become director last year when Max Mayfield retired, but turned down the job due to family reasons.

Tropical update
There are no threat areas in the tropical Atlantic to discuss, and none of the computer models are forecasting tropical storm formation over the coming week. A cold front is expected to push off the U.S. East Coast by Sunday, and we will have to watch the waters off the North Carolina coast then for development when the front stalls out. In the Pacific, an exceptionally large Category 1 typhoon, Man-Yi, is expected to become a major typhoon, and will threaten Japan late this week.

However, I just found this, so I guess you are right:

Unlike Atlantic and Pacific hurricane seasons, they run for the whole year, starting on January 1 and ending on December 31. These dates are when tropical cyclones usually form in the western half of the Pacific Ocean, north of the equator.

During Ivan, our aluminum carport ripped up, half of it ended up in the top of a tree at the end of our street. It cat scratched 3 cars on it's way there. The wind ripped the garage door up. I had to get out in the wind,pull it down and chained it to the rear axle of my car. The pressure change blew every door in the house open. It sucked the attic door up in the attic. I'm sure another second or two and the roof would have been history. It happened to almost every other house on my block.

Ivansurvivr:

We agree, Ivan was scariest yet. . Altho we had flooding as high from Katrina,surprisingly, considering where it made landfall, but the winds were not nearly as bad.

Patrap;

If I had it to do over again, I'd be a Marine.

I worked with the men and women at MFR in New Orleans, from one week before Katrina until last Feb. I've never met a more comitted cadre of people - no griping - just get it done!

Regarding Man-Yi, tonight's diurnal maximum will tell us what this storm is truly capable of becoming.

From the development that has already occurred this evening, one can already see a great increase in central convective activity and the appearance of outflow banding on this storm (on the western side) for the first time - an indicator of an impending cycle of rapid intensification.

I would not be suprised at all if by sunrise that this immense system has attained cat 3 status, and be a super typhoon by this time tomorrow if shear remains kind to it.

They already had 2 typhoons. One was a cat 4 on the SSHS.

Boy was Andrew fun. I was 7 at the time and we were in good old West Palm Beach, Florida

Oh yes. That sure was a fun morning. I was in South Miami. Fun never sounded like that again...yet.

Niceville folks all over this blog!

The lovely town of Niceville.

Don't forget Eloise...that took a lot of trees down around the lakeyard here in Defuniak Springs.

I don't remember a hurricane in the GOM last year. Wonder what the odds are of it happening 2 years in a row.

majkia - Niceville?

Same here. Ivan was worse than Opal in my opinion. Might have been because of the time that it passed over. Listening to your roof gables moan at 2 AM is not a sound I want to hear again any time soon!

Yes, night storms are bad. I remember Wilma lasted from 6:00 am until 2:00 pm the same day! Than of course theres Frances which lasted for 2 days.
664. majkia 1:58 PM GMT on July 10, 2007    
MrNiceville,

Yup, Niceville. We're at the open end of Sarah Ann Bayou.
665. Ivansurvivr 2:02 PM GMT on July 10, 2007    
I remember Katrina .I did some landscaping for a land developer on perdido key. He was lived in the closest house to the beach. His maid left his south facing window open about 5 inches upstairs. He ended up with three feet of sand all across the upstairs of his house. That was a strange sight seeing some guy walking out the front door of a 2mil mansion with a wheelbarrow full of sand.
666. MrNiceville 2:09 PM GMT on July 10, 2007    
Sarah Ann? You must be over by Ward Cove, then...

We're at the intersection of White Point Road and SR 20 - behind the Walgreens.

Ike - it would be nice, 2 years in a row. But I take nothing for granted. When we moved here in '94, we were REPEATEDLY told that there hadn't been a major hurricane in the area in 65 years - then Opal came along and started a new trend!
667. Ivansurvivr 2:10 PM GMT on July 10, 2007    
I wasn't there for opal. I remember seeing it on the news. Ivan was a more head on hit, and was much larger. I heard somewhere (i believe ch3) Ivan was undergoing "eyewall reformation" at landfall which gave it a doublewhammy effect.
668. catastropheadjuster 2:14 PM GMT on July 10, 2007    
I remember Ivan to we left and headed toward Jackson Ms and still couldn't find a hotel.But further up in Ms we did about 2:30 in the morning. Had 6 dogs and a cat w/8 kittens. It was fun trying to sneak them in the room. But when we got home it was horrible trees down everywhere,no power,roof tore up etc. I don't want to see another Ivan or Katrina. It was very bad.

Is anyone else concerned that a storm so large has formed in the West Pacific during the second week of July in a La Nina year?

Storms comparable to this previously have tended to develop later on in August to October, during El Nino years, or those that are neutral with a warm trend.

Much like Gonu earlier this year, Man-Yi is a red flag that things are changing in the tropics in ways that we are unable to predict...
670. sunshineandshowers 2:20 PM GMT on July 10, 2007

Really? That's kinda scary. All the major guys, jtwc, tropicalstormrisk, jma etc... are predicting only a brief spell as a supertyphoon near to Okinawa, 3 days away. That's very worrying, but i agree the storm looks really alive, and those waters are warm.

Man-Yi has some very impressive outflow. I agree that it could be entering a rapid intensification phase. Such good outflow can mix out any dry air near the core very quickly.


On a side note, here's another storm that had impressive outflow:

check out this loop. there are two areas with some form of circulation.
(1) 10N 52W
(2) 8n 29w
THE FIRST IS IN A SHEAR ENVIROMENT WHEREAS THE SECOND IS IN A BETTER ONE ALTHOUGH IT IS A BIT SOUTH

morning. hows my sa blob doing? looks a little more impressive, but why doesnt jeff masters discuss it? is it too close to land to worry about? ike, im having the same issues.
676. Tropicnerd13 2:53 PM GMT on July 10, 2007    
yay, 2 blobbies.

From looking at the GFS model runs..that's the one, #2, with the best chance. It carried it...the moisture...all the way to the SE USA.

Its good to know its not just my computer.

Every tropical season is different. There are so many variables that affect hurricanes that no two seasons will be alike. Had it not been for that huge supertyphoon(IOKE i think) that went south of Hawaii last year, things may have been much different for us. That storm was so large and lasted so long it may well have shifted weather patterns all over the world. It was theorized that the westerly winds to the south of the circulation of that storm triggered the "el nino" pattern that protected us last year. I know there is some correlation between w-pac and atlantic basin seasons. I don't have statistics to back this up, but I know busy w-pac seasons seem to lead to quiet Atlantic seasons. The w-pac has been quiet so far. Not good for us in my opinion. I guess we'll know by december whether I'm right or not. Were all just playing a guessing game at this point
681. IKE 2:58 PM GMT on July 10, 2007    
If there's a major hurricane headed for the US...you will probably NOT be able to access everything on this website. Had that happen with Charley when he was making landfall.

683. Tropicnerd13 3:02 PM GMT on July 10, 2007    
yeah, i remember tracking ioke. didnt it go from closer to the east pacific and travel all the way to the west? does anyone have any pictures of the biggest pacific storm?
684. weathermanwannabe 3:02 PM GMT on July 10, 2007    
With all of these stories on the hurricanes, I hope that the "wishcasters" who have never lived through such an ordeal will take pause...While I enjoy watching cyclogenisis, and discussing the storms and possible strength and land fall once they actually form on this blog (and so that we help warn others to prepare for these things), I can never fathom those who complain when the season is "slow".....Trust us, any landfalling hurricane is tragic and the less storms that we have (although that is "wishfull" thinking)the better off we are...

Hurricanes are no fun to live through.

If there's one headed for the panhandle of Florida, I leave!

k8ecane, i saw that too, and it looks to me like a blob to watch. we really dont need to watch it right now, considering where it is. if it does develop, it would give us something to talk about, but it wouldnt hit land, so theres no point of really being concerned right now.
691. Tropicnerd13 3:11 PM GMT on July 10, 2007    
yeah, me too.

well sinse highs go in clockwise motion and theres 3 over the gulf(or one big one) then it really has a better chance of going out to sea.
697. stoormfury 3:16 PM GMT on July 10, 2007    
what looks to be a tropical disturbance in the making in the far eastern atlantic, will no doubt track west for a long time. the ALT high pressure is very strong and far to the south. this will keep the system on a westerly course for a long time. it is my gut feeling that it could be our next storm

i thought you guys said that noreasters couldnt happen now. patraps picture way up above says otherwise... unless that is just a big swilry thing of clouds (again, a technical term)
