Ernesto and Friends

The TROPICS

Good morning. just a quick update on the tropics this morning which promises to get very busy over the next couple of weeks.

Video update and forecast.



ERNESTO



Tropical Storm Ernesto exited the West Yucatan late night and quickly started to regain strength. Hurricane Hunter Aircraft was there waiting when he made his exit off the coast.

Significant Wind Levels...
Level Wind Direction Wind Speed
1002mb (Surface) 100° (from the E) 61 knots (70 mph)
974mb 100° (from the E) 74 knots (85 mph)
962mb 105° (from the ESE) 72 knots (83 mph)
953mb 100° (from the E) 77 knots (89 mph)
939mb 105° (from the ESE) 76 knots (87 mph)
924mb 115° (from the ESE) 82 knots (94 mph)
854mb 130° (from the SE) 78 knots (90 mph)
843mb 130° (from the SE) 77 knots (89 mph)

While Ernesto appears to be strengthening over the far southern Bay of Campeche this morning, he will be making landfall in a few hours once again. The National Hurricane center has changed it's intensity forecast back up to Hurricane strength at landfall.



It has been discussed that there is a slight possibility of Ernesto making a crossover to the Pacific. There has been model support of this occurring.



92L



92L is the next feature that needs to be watched for development. This feature is close to Tropical Depression status. This should become TD7 sometime today and slowly strengthen to Tropical Storm Gordon over the next couple of days. The National Hurricane Center currently has this at 70% chance of development into a cyclone within the nest 48 hours.



As you can see, 92L is somewhat impressive for an invest. Nice blowup of convection over the circulation, which is obvious in the satellite loops, and good banding features becoming established. As with Ernesto, the models are split as to where he will end up.



The GFS Ensembles are grouped together for the first couple of days and then become widely split after day 3 or so. The indicated anywhere between South America to the Northeast United States.



All the models agree that 92L will become Tropical Storm Gordan on the next couple of days unless, the African wave beats it to the punch. Which is entirely possible.



Florence

Producing a nice little blowup of storms this morning but the NHC gives it neat 0% of development. NEXT



AFRICAN WAVE

This is the feature that truly, has the potential to became a significant Hurricane.

The wave has been very very impressive during it;s travels across the African Continent and already has a decent area of low pressure and even some banding or inflow channels into the low. This will be over water very soon and will be something to watch right out of the box.



The Global models, particularly the GFS has been showing doom with the wave for days. This will be very interesting to watch.

Various model runs will be posted in a bit.

Moisture from tropical wave over Florida, or what ever some of the models have spin up from the left over energy from Ernesto. LOL

Another great update e!! Thanks for all the work you put into these!!

Do any of the models still show a "low" developing in the Carib this weekend, and moving into the Gulf?

Not really anymore san. The CMC is bouncing from the GOM to Florida East coast.

The GFS has totally dropped the African Wave from any development in the last few runs. Wounder what's up with that. They are now developing the two after that one. Crazy

(EDIT) Nevermind my statement above. LOL. Spoke to soon

LOL, No TD7. On rare occasion the NHC decides not to go with the ATCF reports and analysis.

Today, this is one such case. There is no official TD7 and the NHC continues Invest 92L. Trying to pull a Ernesto and it has not even developed yet. WTF

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
ISSUED BY THE HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
200 PM EDT THU AUG 9 2012

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
STORM ERNESTO...LOCATED NEAR COATZACOALCOS MEXICO.

1. A WELL-DEFINED LOW PRESSURE SYSTEM IS LOCATED MIDWAY BETWEEN THE
CAPE VERDE ISLANDS AND THE LESSER ANTILLES. A SMALL AREA OF
SHOWERS AND THUNDERSTORMS IS BECOMING MORE ORGANIZED AROUND THE
CENTER OF CIRCULATION...AND UPPER-LEVEL WINDS APPEAR CONDUCIVE FOR
A TROPICAL DEPRESSION TO FORM LATER TODAY OR TONIGHT. THIS SYSTEM
HAS A HIGH CHANCE...80 PERCENT...OF BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS AS IT MOVES WESTWARD AT ABOUT 15 MPH.

2. A LOW PRESSURE TROUGH...THE REMNANTS OF FLORENCE...IS PRODUCING AN
AREA OF DISORGANIZED SHOWERS AND THUNDERSTORMS SEVERAL HUNDRED
MILES NORTH-NORTHEAST OF THE NORTHERN LEEWARD ISLANDS. ALTHOUGH
UPPER-LEVEL WINDS MAY BECOME A LITTLE MORE CONDUCIVE OVER THE NEXT
COUPLE OF DAYS...SIGNIFICANT REDEVELOPMENT OF THIS SYSTEM IS NOT
EXPECTED AT THIS TIME. THIS SYSTEM HAS A LOW CHANCE...10
PERCENT...OF BECOMING A TROPICAL CYCLONE AGAIN DURING THE NEXT 48
HOURS.

3. A TROPICAL WAVE ACCOMPANIED BY AN AREA OF LOW PRESSURE IS
APPROACHING THE WEST COAST OF AFRICA WITH MINIMAL SHOWER AND
THUNDERSTORM ACTIVITY. SOME DEVELOPMENT OF THIS SYSTEM IS POSSIBLE
OVER THE NEXT COUPLE OF DAYS AS IT MOVES WESTWARD AT 10 TO 15 MPH.
THIS SYSTEM HAS A LOW CHANCE...20 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

TROPICAL DEPRESSION SEVEN DISCUSSION NUMBER 1
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072012
500 PM AST THU AUG 09 2012

LOW CLOUD MOTIONS FROM ANIMATION OF SATELLITE IMAGERY INDICATE THAT
THE AREA OF LOW PRESSURE ACCOMPANYING A TROPICAL WAVE OVER THE
CENTRAL TROPICAL ATLANTIC HAS DEVELOPED A WELL-DEFINED LOW-LEVEL
CIRCULATION. THERE IS SUFFICIENT ORGANIZED DEEP CONVECTION TO
WARRANT THE DESIGNATION OF THE SYSTEM AS A TROPICAL CYCLONE AT THIS
TIME. THE CURRENT INTENSITY ESTIMATE IS 30 KT PENDING OBSERVATIONS
FROM NOAA DATA BUOY 41041...WHICH THE CYCLONE SHOULD PASS NEAR OR
OVER A FEW HOURS FROM NOW. THE SYSTEM IS EXPECTED TO MOVE THROUGH
AN ATMOSPHERIC ENVIRONMENT THAT IS MARGINALLY FAVORABLE FOR
STRENGTHENING...AS THE LGEM GUIDANCE INDICATES SHEAR IN THE 15 TO 20
KT RANGE LATER IN THE FORECAST PERIOD. MOREOVER...THE ECMWF AND GFS
MODELS SUGGEST THAT THE SYSTEM COULD OPEN UP INTO A WAVE IN A FEW
DAYS. THE OFFICIAL INTENSITY FORECAST CALLS FOR ONLY SLOW
STRENGTHENING...AND MORE OR LESS FOLLOWS THE LATEST LGEM GUIDANCE.

A STRONG MID-LEVEL RIDGE IS SITUATED TO THE NORTH OF THE DEPRESSION
AND THE CYCLONE IS MOVING RAPIDLY WESTWARD AT AROUND 17 KT. AN
EVEN FASTER FORWARD MOTION OVER THE NEXT SEVERAL DAYS IS INDICATED
BY THE GLOBAL MODELS...AND BY THE OFFICIAL FORECAST. THE GFDL AND
HWRF MODELS SUGGEST A MORE NORTHWESTWARD TRACK IN THE LATTER PART
OF THE FORECAST PERIOD. THAT SCENARIO SEEMS LESS LIKELY GIVEN THE
STRENGTH OF THE RIDGE FORECAST BY THE GFS AND ECMWF AT THIS TIME.

TROPICAL DEPRESSION SEVEN DISCUSSION NUMBER 7
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072012
500 AM AST SAT AUG 11 2012

THERE HAS BEEN SOME ADDITIONAL INCREASE IN CONVECTION NEAR AND SOUTH
OF THE CENTER OF TROPICAL DEPRESSION SEVEN DURING THE PAST FEW
HOURS. HOWEVER...THE SYSTEM REMAINS DISORGANIZED...AND IT IS
UNCLEAR IF A CLOSED CIRCULATION STILL EXISTS
DUE TO THE RAPID
WESTWARD MOTION. THE INITIAL INTENSITY REMAINS 30 KT BASED ON A
30 KT SATELLITE INTENSITY ESTIMATE FROM TAFB AND CONTINUITY FROM THE
PREVIOUS ADVISORY. AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT
IS SCHEDULED TO INVESTIGATE THE SYSTEM LATER THIS MORNING.

THE INITIAL MOTION REMAINS A RAPID 275/21. THIS MOTION IS EXPECTED
TO CONTINUE THROUGH DISSIPATION AS THE TROPICAL CYCLONE IS STEERED
BY THE ATLANTIC SUBTROPICAL RIDGE TO THE NORTH. THE NEW NHC TRACK
FORECAST IS AGAIN AN UPDATE OF THE PREVIOUS ONE AND LIES CLOSE TO
THE VARIOUS CONSENSUS MODELS.

THE UPPER-LEVEL WINDS ARE MARGINALLY FAVORABLE FOR STRENGTHENING FOR
THE NEXT 12 HR OR SO...AND THE DEPRESSION COULD BECOME A TROPICAL
STORM DURING THAT TIME. AFTER THAT...THE SYSTEM IS FORECAST TO
ENCOUNTER STRONG SOUTHWESTERLY VERTICAL WIND SHEAR...WHICH SHOULD
CAUSE IT TO WEAKEN AND DISSIPATE AS FORECAST BY THE DYNAMICAL MODEL
GUIDANCE. THE NEW FORECAST NOW CALLS FOR DISSIPATION NEAR THE
48 HR POINT.

GIVEN THE CONTINUING UNCERTAINTY AS TO WHETHER THE DEPRESSION WILL
BECOME A TROPICAL STORM...TROPICAL STORM WATCHES CONTINUE FOR PART
OF THE LESSER ANTILLES...EVEN THOUGH TROPICAL STORM CONDITIONS
WOULD REACH THOSE LOCATIONS WITHIN THE NEXT 12 TO 24 HOURS.

FORECAST POSITIONS AND MAX WINDS

INIT 11/0900Z 14.0N 56.1W 30 KT 35 MPH
12H 11/1800Z 14.2N 59.4W 35 KT 40 MPH
24H 12/0600Z 14.4N 63.5W 35 KT 40 MPH
36H 12/1800Z 14.6N 67.6W 35 KT 40 MPH
48H 13/0600Z...DISSIPATED



93L looks to be going POOF

The great apocalyptic hypercane that was going to blast the east coast a few days ago on the GFS 300 hour + model runs didn't come to be. What do we do now?

Look out Bermuda!

On a serious note, what happened to the Bermuda High? A week ago the "pattern" was set in some circles but to me seems the high is weakening and should promote recurves from the east ATL for any CV systems among other variables.

The earlier season home grown prediction is looking good methinks. Sept/Oct might be interesting for anything festering in the WCARB/GULF.

Trough after trough weakening the High. There were some places that had record lows for the past couple of mornings from the latest trough. Just North of Nashville, my Aunt was in the low 50's for the past couple of mornings. Low tonight, 56. Western Caribbean and GOM are the real danger zones now. With this type of pattern, no where to go but Northward.

Thanks E. Was just checking out my "home" forecast in MO and after a brief warm up mid-week there's a cool off in store late week with lows in the 50's and highs in the 70's. Quite the difference from the 100-105 daytime temps while I was there two weeks ago. The troughs are digging for sure.

Good Morning peeps!!

I do not know where to grab images that can be saved on the model runs, but it looks like the GFS Operational 18z 00z and 06z all show something spinning up in the BOC around the 17th, and headed north....two of the runs show a low headed toward far NE Gulf/FL panhandle area....and one model shows the low running north into south TX....All three runs show the Low near landfall around 8/20 or 8/21.

e....can you look at the models and see if this description looks accurate, or not, or somewhere in between....lol? I did not see anything on either the GFS or Euro ensembles, though..... and as a side note...I don't generally look at the models, and am not well versed with them!!!!

You are correct San.

The GFS has been showing development for the past several runs. This latest run would been the perfect scenario for the states that have been plagued by the drought, but, I would not count on it happening this way.

Thanks e!!!

How reliable are the operational models in comparison to the ensemble? Don't quite understand how the operational can show three runs with a Low, and I could not see one moving into the Gulf on the ensemble.....

Kinda off topic and E, I know you HATE this map....lol, but there may be some relief to the extremely drought stricken areas of the midwest.
