Atlantic Tropical Action 2011 - Part IV


Recommended Posts

Yellow, Orange, Red, Hurricane... yep its getting close to peak season in the tropics.

Indeed... didn't really expect them to put out the yellow for that blob SSE of Katia... but I suppose at some point we have to have a 1999 Emily again (joking, of course). I'm really surprised the BOC isn't an invest yet.

It looks like the OV/Tenn valley mega trough/ULL won't lift on time, but the base can be far enough north to not pull whatever forms in the BoC, if it slowly brews, doesn't become large and it stays south of 22N, so a narrow ridge can build to it's north... else it will get pulled N/NE... unfortunately for the TX folks I think future Nate will be either MX or LA east...hopefully I'm wrong.

Nothing I have seen in the globals or their ensembles give any hope for optimism. The natural gas lease that borders my back yard is thickly forested, cut out only for roads and wells and equipment. Never thought about wild fire before.

It is hard to keep my natural born optimism up with all the trees dead or on fire. But a South Florida major will do a lot to lift my sagging spirits. Nothing against Mexico, but I don't see many excellent YouTubes.

Now, Cancun/Cozumel, the tourists help out down there. I know part of Charley was the last Cat 4 to hit the US, but I think population density/affluence helps with quality video.

If opal was a microcane arrowheadsmiley.png

12Z UKIE has a low in the GOM also, but keeps it more or less trapped farther south. Bottom line- how the upper low in the OH/TN Valley area evolves will have a lot to say about this- I am now quite confident about development, but have yet to fully buy into it coming north.

every good season has a NGOM collapser

Pessimist. Glass half full, rapid intensification phase for Opal.

HURRICANE OPAL DISCUSSION NUMBER 26

NATIONAL WEATHER SERVICE MIAMI FL

11 PM EDT TUE OCT 03 1995

RECON PLANE INDICATE THAT OPAL IS INCREASING IN FORWARD SPEED...

THE PRESSURE HAS DROPPED TO 948 MB AND THAT WINDS HAVE INCREASED

TO 100 KNOTS. PLANE REPORTED A PEAK WIND 112 KNOTS AT FLIGHT LEVEL.

THEREFORE...OPAL IS A NOW A CAT 3 ON THE SAFFIR-SIMPSON SCALE. SOME

FLUCTUATIONS IN INTENSITY ARE LIKELY BEFORE LANDFALL.

WITH THE PRESENT ACCELERATION THE HURRICANE SHOULD REACH THE COAST

WITHIN 24 HOURS WITHIN THE AREA OF HURRICANE WARNING ISSUED AT 0300

UTC. INITIAL MOTION IS 035/18. THIS GENERAL TRACK IS EXPECTED TO

CONTINUE DURING THE NEXT 24 TO 36 HOURS AS INDICATED BY MOST OF THE

TRACK MODELS.

HURRICANE OPAL DISCUSSION NUMBER 27

NATIONAL WEATHER SERVICE MIAMI FL

5 AM EDT WED OCT 04 1995

HURRICANE HUNTERS FOUND PEAK WINDS OF 152 KNOTS AT 700 MB...

AND WE ARE ESTIMATING 130-KT MAXIMUM SURFACE WINDS. THE EYE

HAD REPORTEDLY SHRUNK TO 7 N MI IN DIAMETER...INDICATING THAT

OPAL IS PROBABLY NEAR THE END OF AN EYEWALL CONTRACTION. IT IS

VERY RARE FOR HURRICANES TO MAINTAIN SUCH A SMALL EYE FOR VERY

LONG...AND SOME FLUCTUATIONSIN STRENGTH WILL LIKELY OCCUR DUE

TO EYEWALL CYCLES. HOWEVER OPAL IS EXPECTED TO REMAIN A

DANGEROUS CAT 4 HURRICANE UP TO LANDFALL. EVEN THOUGH

THE GREATEST IMPACT OF OPAL WILL BE ON THE IMMEDIATE COAST...

THE RAPID FORWARD MOTION WILL ALLOW DAMAGING HURRICANE FORCE

WINDS TO PENETRATE WELL INLAND. HIGH WIND WATCHES AND WARNINGS

FOR HURRICANE FORCE WINDS WILL BE ISSUED BY NATIONAL WEATHER SERVICE

OFFICES WHERE APPROPRIATE.

INITIAL MOTION ESTIMATE IS 020/19...AND A LITTLE FURTHER ACCELERATION

IS POSSIBLE DURING THE NEXT 12 HOURS OR SO. THE OFFICIAL FORECAST

TRACK IS SOMEWHAT FASTER THAN THE PREVIOUS ONE...BUT ALONG BASICALLY

THE SAME PATH. THIS IS IN BETWEEN THE GFDL AND DEEP-LAYER BAM...BUT

CLOSER TO THE GFDL IN SPEED. IT IS IMPORTANT NOT TO FOCUS ON THE EXACT

TRACK...GIVEN THE LARGE EXTENT OF DAMAGING WINDS AND STORM SURGE.

PREPARATIONS OVER THE WARNING AREA SHOULD BE RUSHED TO COMPLETION.

I was a junior in HS, but I couldn't believe how fast that ramped up during the day, while near the loop current.

Yep, it was a shocker. I was home from work because it happened on Yom Kippur, and it was like, "Omg!!1!" I remember that the NHC advisory had a special request-- to warn Jewish neighbors of the coming storm, since it ramped up and accelerated so fast toward the coast on a day when Jooz don't use electricity and wouldn't have the TV on.

Look for this one to be a monster weight_lift.gif

Most active seasons have a big August storm and a big September storm.

Examples:

2003

Aug: Fabian

Sept: Isabel

2004

Aug: Charley/Frances

Sept: Ivan/Jeanne

2005

Aug: Katrina

Sept: Rita

2007

Aug: Dean

Sept: Felix

2008

Aug: Gustav

Sept: Ike

2010

Aug: Earl

Sept: Igor/Karl

2011

Aug: Irene

Sept??

At this rate, I'd guess Hurricane Philippe or Hurricane Rina would be a biggie for September.

Maybe Alpha will be the big one! Seems like it is getting close to a given that we will get the rest of the names, with half of the season to go, a warm Atlantic and a developing La Nina. October might be quite a fun month as well.... ???

Honestly getting to the Greek Alphabet is certainly a possibility. We made it to T last year, and we are currently 6 named storms ahead of 2010. In fact, we are only one storm behind 2005 right now, and if things continue to remain active, we could theoretically reach the P named storm before 2005 did (Philippe 2005 developed on September 17th).

:wub:

I totally dig October. A lot of my of my all-time favorite 'canes were October ones: King 1950, Hazel 1954, Hattie 1961, Joan 1988, Iris 2001 (:wub:), and of course Wilma 2005. Lots of great treausres from the tenth month.

Throw in a good divergence spike too early-mid October.

LOL just being realistic. It would be nice to have some hurricanes along with these storms though. The Atlantic season isn't even above the Mendoza line in percentage of storms to make hurricanes yet. Yuck.

The one difference to 2010 is that the storms sure did like the deep tropics more that year. 2011 has had them everywhere from all types of developments. Hard to find many analogs really.

October has a bunch of things going for it. La Nina emerging. Shear anomalies being the lowest below average in the Caribbean so far. Really warm waters. Low-level westerly anomalies. The crystal ball is hazy still on exactly when, but I can see us being set up for a memorable end of the year. A lot of that variability is so random though. 2010 early anomalies were just as good, if not better than this year, yet no majors in the Carib for October (of course there were many many hurricanes).

3 storm outbreak and the board seems pretty quiet. I guess if it isn't headed toward the US immediately it is a big ho-hum lol.

If there are any complaints, just remember to send them to the eastern Pacific! Talk about a shutdown!

I have always preferred the longer tracks, but October sure packs a mean wallop if the conditions are right.
