TROPICAL DEPRESSION NINE-E ADVISORY NUMBER 11
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP092009
200 AM PDT WED AUG 12 2009
...DEPRESSION REMAINS POORLY-ORGANIZED...
AT 200 AM PDT...0900 UTC...THE CENTER OF TROPICAL DEPRESSION NINE-E
WAS LOCATED NEAR LATITUDE 14.7 NORTH...LONGITUDE 131.3 WEST OR ABOUT
1510 MILES...2425 KM...WEST-SOUTHWEST OF THE SOUTHERN TIP OF BAJA
CALIFORNIA.
THE DEPRESSION IS MOVING TOWARD THE WEST NEAR 13 MPH...20
KM/HR...AND THIS GENERAL MOTION IS EXPECTED TO CONTINUE FOR THE
NEXT 48 HOURS.
MAXIMUM SUSTAINED WINDS REMAIN NEAR 30 MPH...45 KM/HR...WITH HIGHER
GUSTS. LITTLE CHANGE IN STRENGTH IS FORECAST DURING THE NEXT 48
HOURS.
ESTIMATED MINIMUM CENTRAL PRESSURE IS 1007 MB...29.74 INCHES.
...SUMMARY OF 200 AM PDT INFORMATION...
LOCATION...14.7N 131.3W
MAXIMUM SUSTAINED WINDS...30 MPH
PRESENT MOVEMENT...WEST OR 260 DEGREES AT 13 MPH
MINIMUM CENTRAL PRESSURE...1007 MB
THE NEXT ADVISORY WILL BE ISSUED BY THE NATIONAL HURRICANE CENTER AT
800 AM PDT.

FORECASTER PASCH
TROPICAL DEPRESSION NINE-E DISCUSSION NUMBER 11
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP092009
200 AM PDT WED AUG 12 2009
THE DEPRESSION IS HANGING ON AS A MARGINAL TROPICAL CYCLONE AT THIS
TIME...WITH A FEW BURSTS OF DEEP CONVECTION MAINLY EAST AND
NORTHEAST OF THE LOW-LEVEL CENTER. ALTHOUGH VERTICAL SHEAR OVER
THE AREA HAS RELAXED...IT APPEARS THAT THE SYSTEM IS NOT IN A VERY
FAVORABLE THERMODYNAMIC ENVIRONMENT. IF THE DEPRESSION IS ABLE TO
SURVIVE FOR ANOTHER DAY OR TWO...HOWEVER...THE SHIPS AND LGEM
MODELS INDICATE THAT IT WILL EVENTUALLY ENCOUNTER CONDITIONS MORE
CONDUCIVE FOR STRENGTHENING. THE OFFICIAL FORECAST IS BASED ON
THIS PREMISE...BUT...GIVEN THE LOWLY CURRENT STATE OF THIS TROPICAL
CYCLONE...CONFIDENCE IN THE INTENSITY FORECAST IS NOT HIGH.
SATELLITE FIXES CONTINUE TO INDICATE A SLIGHTLY SOUTH OF WEST
MOTION...ABOUT 265/11. A WEST-SOUTHWEST TO EAST-NORTHEAST-ORIENTED
LOW- TO MID-LEVEL RIDGE TO THE NORTH OF THE DEPRESSION...ALONG WITH
BROAD CYCLONIC LOW-LEVEL FLOW TO THE SOUTH AND SOUTHEAST...SEEM TO
BE CONTROLLING THE MOTION OF THE SYSTEM. THE CONSENSUS OF THE
TRACK GUIDANCE IS FOR A MAINTENANCE OF A SLIGHTLY SOUTH OF WESTWARD
MOTION FOR THE NEXT SEVERAL DAYS. NEAR THE END OF THE FORECAST
PERIOD...THE RIDGE TO THE NORTH OF THE TROPICAL CYCLONE IS FORECAST
TO WEAKEN BY THE GLOBAL MODELS. HENCE THE OFFICIAL FORECAST SHOWS
A GRADUAL TURN TO THE RIGHT AT A SLOWER FORWARD SPEED AT DAYS 4-5.
THE NHC TRACK IS JUST A BIT TO THE SOUTH OF THE ONE FROM THE
PREVIOUS ADVISORY PACKAGE.

TROPICAL DEPRESSION NINE-E DISCUSSION NUMBER 12
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP092009
800 AM PDT WED AUG 12 2009
THERE HAS BEEN LITTLE CHANGE THIS MORNING WITH THE TROPICAL
DEPRESSION...WHICH IS MAINTAINING JUST ENOUGH CONVECTION TO KEEP IT
FROM BEING CONSIDERED A REMNANT LOW. WATER VAPOR IMAGERY SHOWS
THAT THE IMMEDIATE ENVIRONMENT OF THE CYCLONE IS FAIRLY DRY...AND
WHILE THE SHEAR IS LIGHT...THE UPPER-LEVEL FLOW OVER THE SYSTEM
APPEARS TO BE SOMEWHAT CONVERGENT. NEVERTHELESS...THE STATISTICAL
INTENSITY GUIDANCE MODELS STRENGTHEN THE SYSTEM NEAR THE END OF THE
FORECAST PERIOD...AS DOES THE GFDL. IN THE CASE OF SHIPS THE
DRIVING PREDICTOR IS THE SST POTENTIAL...BUT THIS IS IN FACT NO
LESS FAVORABLE NOW THAN IT WILL BE IN FIVE DAYS...SO I AM
SKEPTICAL. THE OFFICIAL FORECAST WILL STILL REFLECT THE POSSIBILITY
OF SOME STRENGTHENING AND IS CLOSE TO THE CONSENSUS AID ICON.
THE INITIAL MOTION ESTIMATE IS 265/12. THE DEPRESSION IS EXPECTED
TO CONTINUE ON THIS GENERAL TRACK TO THE SOUTH OF A LOW- TO
MID-LEVEL RIDGE FOR THE NEXT TWO TO THREE DAYS. THE TRACK BECOMES
LESS CLEAR BEYOND THAT POINT...AS THE CYCLONE NEARS THE WESTERN
EXTENT OF THE SUBTROPICAL RIDGE AND ENCOUNTERS SOME UPPER-LEVEL
SOUTHERLY FLOW. OF COURSE...THE SYSTEM MIGHT NOT BE SIGNIFICANT
ENOUGH OR DEEP ENOUGH TO FEEL THESE INFLUENCES. THE OFFICIAL
FORECAST CALLS FOR A GRADUAL SLOWING OF THE FORWARD SPEED BUT NOT
MUCH CHANGE IN DIRECTION...AND IS CLOSEST TO A BLEND OF THE UKMET
AND HWRF. ON THE OTHER HAND...THE ECMWF AND GFDL SHOW AN
INTERACTION BETWEEN THE DEPRESSION AND THE DEVELOPING SYSTEM TO ITS
EAST...AND CONSEQUENTLY INDICATE A MUCH SHARPER SLOWDOWN AND TURN
TO THE NORTH.

Re: EPAC : TROPICAL DEPRESSION NINE-E
If it gets a name before crossing 140 it will be Guillermo, if it gets named after crossing 140 it will be the next name on the Hawaiian list, Neki. I wonder if it would be a record, having three named CPAC systems within one month?

Guillermo or Hilda, remember that 10-E is looking much better and could be named earlier.

IMO, 10E should be named at the next advisory, so this might be Hilda (a backwards-order, similar to Humberto and Ingrid in 2007).

THIS GENERAL MOTION IS EXPECTED TO CONTINUE FOR THE NEXT DAY OR TWO
WITH A GRADUAL DECREASE IN FORWARD SPEED.
MAXIMUM SUSTAINED WINDS ARE NEAR 35 MPH...55 KM/HR...WITH HIGHER
GUSTS. LITTLE CHANGE IN STRENGTH IS FORECAST OVER THE NEXT COUPLE
OF DAYS.
ESTIMATED MINIMUM CENTRAL PRESSURE IS 1007 MB...29.74 INCHES.

200 PM PDT WED AUG 12 2009
ALTHOUGH CONVECTION REMAINS MINIMAL...THE MOST RECENT QUIKSCAT PASS
REQUIRES THAT THE WINDS BE ADJUSTED TO 30 KT. THE QUIKSCAT PASS
ALSO REVEALED THAT THE CIRCULATION MAY BE STARTING TO LOSE
DEFINITION. BETWEEN THE LIMITED CONVECTION AND THE MARGINAL
CIRCULATION...THE DEPRESSION COULD DEGENERATE TO A REMNANT LOW OR
DISSIPATE AT ANY TIME. THE SHIPS...LGEM...AND GFDL ALL INDICATE
THAT THE CYCLONE WILL RESTRENGTHEN...WHILE THE GFS AND ECMWF SHOW
DISSIPATION. AS NOTED EARLIER...WATER VAPOR IMAGERY SHOWS
THAT THE IMMEDIATE ENVIRONMENT OF THE CYCLONE IS FAIRLY DRY...AND
WHILE THE SHEAR IS LIGHT...THE UPPER-LEVEL FLOW OVER THE SYSTEM
APPEARS TO BE SOMEWHAT CONVERGENT. THE OFFICIAL FORECAST NOW FAVORS
THE GLOBAL MODEL...AND HWRF...SOLUTIONS AND NO LONGER SHOWS
REDEVELOPMENT.
THERE IS ALSO A LARGE DIVERGENCE IN THE TRACK GUIDANCE...WITH THE
GFS...ECMWF...BAM SHALLOW AND GFDL SHOWING A SLOW MOTION AND
EVENTUAL INTERACTION WITH THE NEW TROPICAL CYCLONE TO THE EAST.

200 PM PDT WED AUG 12 2009
ALTHOUGH CONVECTION REMAINS MINIMAL...THE MOST RECENT QUIKSCAT PASS
REQUIRES THAT THE WINDS BE ADJUSTED TO 30 KT. THE QUIKSCAT PASS
ALSO REVEALED THAT THE CIRCULATION MAY BE STARTING TO LOSE
DEFINITION. BETWEEN THE LIMITED CONVECTION AND THE MARGINAL
CIRCULATION...THE DEPRESSION COULD DEGENERATE TO A REMNANT LOW OR
DISSIPATE AT ANY TIME. THE SHIPS...LGEM...AND GFDL ALL INDICATE
THAT THE CYCLONE WILL RESTRENGTHEN...WHILE THE GFS AND ECMWF SHOW
DISSIPATION. AS NOTED EARLIER...WATER VAPOR IMAGERY SHOWS
THAT THE IMMEDIATE ENVIRONMENT OF THE CYCLONE IS FAIRLY DRY...AND
WHILE THE SHEAR IS LIGHT...THE UPPER-LEVEL FLOW OVER THE SYSTEM
APPEARS TO BE SOMEWHAT CONVERGENT. THE OFFICIAL FORECAST NOW FAVORS
THE GLOBAL MODEL...AND HWRF...SOLUTIONS AND NO LONGER SHOWS
REDEVELOPMENT.
THERE IS ALSO A LARGE DIVERGENCE IN THE TRACK GUIDANCE...WITH THE
GFS...ECMWF...BAM SHALLOW AND GFDL SHOWING A SLOW MOTION AND
EVENTUAL INTERACTION WITH THE NEW TROPICAL CYCLONE TO THE EAST.
THE OFFICIAL FORECAST HAS BEEN SLOWED SIGNIFICANTLY RELATIVE TO THE

Re: EPAC : TROPICAL DEPRESSION NINE-E
Are my eyes deceiving me, or does is TD 10 forecast to Leap Frog TD 9? I don't understand how this can happen.

THE CLOUD PATTERN HAS CONTINUED TO DETERIORATE AND THE SHOWER
ACTIVITY IS MINIMAL. THE CIRCULATION HAS ALSO BECOME ELONGATED.
THIS SYSTEM IS NOW A REMNANT LOW BUT IT COULD STILL BE ABLE TO
TRIGGER A FEW BURSTS OF CONVECTION. THE LOW IS EXPECTED TO MOVE
TOWARD THE WEST-SOUTHWEST ABOUT 8 TO 10 KNOTS UNTIL DISSIPATION.
GUIDANCE SHOWS THAT THE SYSTEM HAS THE POSSIBILITY OF RE-GENERATION
DURING THE NEXT FEW DAYS AND IF IT DOES...ADVISORIES WILL BE
RE-INITIATED BUT FOR NOW...THIS IS THE LAST ONE. ADDITIONAL
INFORMATION ON THIS SYSTEM CAN BE FOUND IN HIGH SEAS FORECASTS
