ACCUMULATIONS OF 3 TO 6 INCHES OVER THE MEXICAN STATES OF
VERACRUZ...TABASCO...PUEBLA...AND OAXACA THROUGH FRIDAY NIGHT.
ISOLATED MAXIMUM STORM TOTAL AMOUNTS OF 15 INCHES ASSOCIATED WITH
ERNESTO ARE POSSIBLE. THESE RAINS MAY PRODUCE LIFE-THREATENING
FLASH FLOODS AND MUD SLIDES OVER AREAS OF HIGHER TERRAIN.

STORM SURGE...A STORM SURGE OF 1 TO 3 FEET ABOVE NORMAL TIDE LEVELS
IS POSSIBLE IN AREAS OF ONSHORE WINDS IN THE WARNING AREA. NEAR THE

If you speed this live loop up you can see the decapitation in process. The LLC has obviously slammed into the mountains.

TROPICAL STORM ERNESTO DISCUSSION NUMBER 35
NWS NATIONAL HURRICANE CENTER MIAMI FL AL052012
1000 PM CDT THU AUG 09 2012

DEEP CONVECTION HAS DECREASED SUBSTANTIALLY NEAR THE CENTER OF
ERNESTO OVER THE THE PAST FEW HOURS...AND THE INTENSITY HAS BEEN
REDUCED TO 35 KT FOR THIS ADVISORY. ADDITIONAL WEAKENING IS
EXPECTED AS THE CYCLONE CONTINUES MOVING INLAND OVER THE HIGH
TERRAIN OF SOUTHERN MEXICO...AND THE LOW-LEVEL CIRCULATION IS
FORECAST TO DISSIPATE BY 24 HOURS.

THE INITIAL MOTION ESTIMATE IS 265/12...A LITTLE FASTER THAN BEFORE.
THIS GENERAL MOTION SHOULD CONTINUE UNTIL DISSIPATION AS ERNESTO IS
STEERED A LITTLE SOUTH OF DUE WEST BY THE SUBTROPICAL RIDGE
CENTERED OVER NORTHERN MEXICO AND THE SOUTHWESTERN UNITED STATES.

ALTHOUGH THE LOW-LEVEL CIRCULATION OF ERNESTO IS FORECAST TO
DISSIPATE OVER THE HIGH TERRAIN...THE GLOBAL MODELS CONTINUE TO
SUGGEST THAT A NEW TROPICAL CYCLONE COULD DEVELOP IN THE EASTERN
PACIFIC ASSOCIATED WITH THE MID-LEVEL REMNANT CIRCULATION IN 2 TO 3
DAYS. PLEASE SEE THE EASTERN PACIFIC TROPICAL WEATHER OUTLOOK
FOR MORE INFORMATION ON THIS POSSIBILITY.

VERY HEAVY RAINFALL IS EXPECTED TO CONTINUE EVEN AFTER ERNESTO
DISSIPATES...AND THESE RAINS WILL LIKELY PRODUCE FLASH FLOODING
OVER MUCH OF SOUTHERN MEXICO FOR THE NEXT DAY OR TWO.

Incredible black IR depth while over land!

[KWT]

ECM makes a strong TS out of Ernesto/remains in the EPAC, looks like there is more then enough left of Ernesto to develop in the EPAC, whether its classed as Ernesto or not.

[cycloneye]

Up to 60%.

A LARGE AREA OF DISTURBED WEATHER ALONG THE SOUTHERN COAST OF MEXICO
IS ASSOCIATED WITH THE BROAD CIRCULATION OF WEAKENING TROPICAL
DEPRESSION ERNESTO. ENVIRONMENTAL CONDITIONS ARE FAVORABLE FOR THIS
DISTURBANCE TO DEVELOP AS IT MOVES WESTWARD AWAY FROM THE COAST OF
MEXICO. THERE IS A HIGH CHANCE...60 PERCENT...OF TROPICAL CYCLONE
FORMATION DURING THE NEXT 48 HOURS.

[tolakram]

Looks to me like the circulation dissipated last night. You can see the mountains in this loop.

[tolakram]

30 frame live loop. The sat had all kinds of issues last night so you'll have to turn off all the bad frames.

You could make the case, I suppose, that some kind of circulation made it into the Pacific. I'll let the NHC make that call and agree with whatever they say.

[tolakram]

First Visible. Is that what remains of the LLC, stuck on the edge of the mountains?

[tolakram]

More frames will be available soon, but last to frames seem to show what's left of the LLC.

http://wwwghcc.msfc.nasa.gov/cgi-bin/ge ... umframes=5

[tolakram]

Had it moved due south it might have made it, but too many mountains in the way, IMO.

[Extratropical94]

1st question: Does a storm that crosses over really keep its original name? I'm thinking of storms like Hurricane Joan-Miriam that kept intact throughout the land passage and still got renamed...

2nd question: Now, that Ernesto is officially declared dissipated, is it 100% certain that the EPAC system will not be named Ernesto again?

3rd question: Is there a thread for that 60% disturbance yet?

Any comments or answers are appreciated. Thanks in advance.

[tolakram]

NHC discussion tells you. No thread for the remains yet.

REMNANTS OF ERNESTO DISCUSSION NUMBER 37
NWS NATIONAL HURRICANE CENTER MIAMI FL AL052012
1000 AM CDT FRI AUG 10 2012

SURFACE OBSERVATIONS FROM MEXICO INDICATE THAT THE LOW-LEVEL CENTER
OF CIRCULATION HAS BECOME DISRUPTED BY THE HIGH TERRAIN AND IS NO
LONGER TRACKABLE. ERNESTO NOW CONSISTS OF A BROAD AREA OF LOW
PRESSURE OVER SOUTHERN MEXICO. HEAVY RAINFALL ASSOCIATED WITH THE
REMNANTS OF ERNESTO WILL CONTINUE DURING THE NEXT DAY OR TWO.
THESE RAINS WILL LIKELY PRODUCE FLASH FLOODING OVER MUCH OF
SOUTHERN MEXICO.

THE REMNANTS OF ERNESTO ARE EXPECTED TO MOVE OFF MEXICO INTO THE
EASTERN PACIFIC WITH THE POTENTIAL TO BECOME A TROPICAL CYCLONE. IF
THIS IS THE CASE...IT WILL ACQUIRE A NEW DEPRESSION NUMBER...OR A
NEW NAME IF IT BECOMES A TROPICAL STORM.

THIS IS THE LAST ADVISORY ISSUED BY THE NATIONAL HURRICANE CENTER ON
ERNESTO.

Thanks Mark, I haven't read that disco yet.
I guess there's no need to make one then as long as it's not a numbered TC.

You can start one in Talking Tropics if you want, I'm sure someone will at some point. I would like to think they will activate an invest in the EPAC soon, but really no clue.

1st answer: Nope. Whenever a storm's center of circulation is >50% into the EPAC or ATL basins, the storm is assigned the upcoming name from the basin that the storm crossed into. For example, if Ernesto survives his trip across Mexico, he will be renamed Ernesto-Hector.

2nd answer: See above.

3rd answer: Yes. Look below the thread for Florence.

Hi greenkat, do you have a source for #1. Not familiar with the two-name designation.

Based on my info I think the policy is rather simple. If the LLC survived it would keep the same name, otherwise it will be treated as a new EPAC storm. Since the NHC has declared Ernesto as dissipated a new name will be given if the remnants 'regenerate'.
