August 2012 Tropical Atlantic Observations And Discussions


NEG NAO

Recommended Posts

Every year the models smoke a few joints and spit out doom tracks for the northeast. The odds of this happening are extremely low and I wouldn't buy a scenario like the one that is shown even if most of the models had it. Tropical cyclone tracks can change from run to run, and posts like the GGEM ensemble porn belong in the banter thread. In order to get a cyclone up here with that type of strength you would need for it be aborbed into a negatively tilted trough and you would need blocking. Otherwise you have the westerlies and the problem with cold SST. The TC simply can not make it up this far north fast enough before either the westerlies push them offshore or they weaken for a variety of other reasons. You need a fast moving TC which has been absorbed or partially absorbed into a negatively tilted through. A trough that deep and that strong is not exactly easy to come by during the Summer.

Which is why a strike here before say 8/25 is extremely rare...deeper troughs in Sept, so more likely then.....

TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

200 PM EDT TUE JUL 31 2012

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. A TROPICAL WAVE WITH AN EMBEDDED AREA OF LOW PRESSURE IS LOCATED

NEARLY MIDWAY BETWEEN AFRICA AND THE LESSER ANTILLES. SHOWERS AND

THUNDERSTORMS ASSOCIATED WITH THIS DISTURBANCE HAVE BECOME SLIGHTLY

BETTER ORGANIZED SINCE YESTERDAY. ENVIRONMENTAL CONDITIONS ARE

CONDUCIVE FOR SOME GRADUAL DEVELOPMENT OF THIS LOW OVER THE NEXT

FEW DAYS. THIS SYSTEM HAS A MEDIUM CHANCE...30 PERCENT...OF

BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES

WESTWARD AT AROUND 15 MPH.

2. A WESTWARD-MOVING TROPICAL WAVE OVER THE CENTRAL CARIBBEAN IS

PRODUCING WIDESPREAD CLOUDINESS AND THUNDERSTORMS FROM HISPANIOLA

EASTWARD FOR SEVERAL HUNDRED MILES. UPPER-LEVEL WINDS ARE NOT

FAVORABLE FOR DEVELOPMENT...AND THIS SYSTEM HAS A LOW CHANCE...NEAR

0 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48

HOURS. HEAVY RAINS AND GUSTY WINDS ASSOCIATED WITH THIS WAVE WILL

SPREAD OVER HISPANIOLA...EASTERN CUBA...AND THE SOUTHEASTERN

BAHAMAS DURING THE NEXT DAY OR TWO.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE

NEXT 48 HOURS.

This one is a fighter. It's really low in latitude and continuously firing convection. All its gonna need is the bath water in the carribean/gulf and favorable upper levels to explode. Im still waiting for the euro and gfs to get a better handle on it..

With a developing persistent NE trough, prospects for a tropical impact for the Northeast look very small for the foreseeable future into the end of August.

Sounds good to me... While tracking Irene was fun last summer, the end result was rather upsetting.. It ruined one of the last few weekends of the summer. Plus, it just ended up being a big old mess.. No real crazy damage.. Just run of the milll crap..

The whole hurricane thing up here in this part of the country is cool, but it's just not worth it.. It messes everything up and what you end up with is a weakening storm as it approaches with several peeps on here going- "i think it's going to strengthen as it approaches the gulf stream.."

The bottom line is that a hurricane up here just doesn't happen very often and rarely (if ever) does it come in at an angle that would make it "meteorologically" interesting for the NYC area..

Irene may have not been the armageddon some were fearing, but it was much more than just a nuisance event, and it was hardly a bust for most places. Widespread tree damage, over 1.5 million homes and businesses losing power in NJ alone with many places being without power for several days to even weeks, a storm surge on LI on par with the December 1992 nor'easter, destructive river flooding throughout northern and central NJ, etc. It was the worst flooding and probably the strongest winds that I've ever witnessed. Hardly run of the mill and certainly meteorologically interesting. I'd take another event like that in a heartbeat. I'm not sure what your expectations are, but if they're for a Cat 2 or 3 storm hitting our area directly, then you will almost always be disappointed. This is the northeastern U.S., not the tropics.

I could do without the damage that's for sure. Tree on my house that we couldn't get removed for two weeks because all the tree guys were busy, power out for five days and the basement flooded for the second time in a month. It took me about six weeks to clean up and then the Oct snowstorm brought down seven more trees that had been weakened in Irene. I'm still dealing with the remnants from that. If we don't have a good tropical storm until next year I'm fine with it.

Keep an eye on the new invest that just pushed off Africa. The environment is conducive for slow steady strengthening and as usual the globals are all over the place, but the overall trend is that things could be interesting over the next week or two. The 00z ECMWF ensemble mean had this making it 70W before recuriving. The GFS is more "Andrew Esque" in terms of track with a bend back towards the WNW just NE of Puerto Rico. Just something to keep an eye on in what has been a rather slow tropical season this far.

Buoy South of Islip now right about 26º, and one of the 12Z GFS ensemble members hits or barely misses Eastern Long Island with a sub 984 mb storm from 94L (Time steps make it impossible to tell if it actually hits). 12Z ensemble trend is your friend. 94L recurve coming later and later as compared to earlier ensemble runs.

94L may be NYC subforums chance at a storm this year, and perhaps a storm on par w/ Gloria. Awfully early, low confidence, but I'm a natural optimist.
