this is the right course of action. If anything, based upon the latest QS, it should be DOWNGRADED as it is just a braod monsoon circulation,

TROPICAL DEPRESSION THREE-E DISCUSSION NUMBER 2
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 PM PDT SUN JUN 26 2005

THE POSITION OF THE DEPRESSION IS VERY DIFFICULT TO DETERMINE THIS
EVENING...ALTHOUGH AN SSMI PASS AT 0045Z AND THE ACAPULCO RADAR
SUGGEST THAT THE CENTER IS SOUTHEAST OF THE DEEP CONVECTION.
LOCATION UNCERTAINTY CLOUDS THE DVORAK CLASSIFICATIONS...WHICH WERE
2.5 FROM AFWA AND TAFB AND 2.0 FROM SAB. GIVEN THIS UNCERTAINTY...
I PREFER TO HOLD THE INTENSITY ESTIMATE AT 30 KT. ALL MODEL
GUIDANCE SUGGESTS THAT THE CYCLONE WILL STRENGTHEN. IN FACT...THE
GFDL MAKES THE SYSTEM A HURRICANE WITHIN 24 HOURS. THE SHIPS MODEL
IS LESS AGGRESSIVE. THE OFFICIAL FORECAST FOLLOWS A BLEND OF THIS
GUIDANCE BUT SHOULD THE EATERLY SHEAR NOT DIMINISH THIS FORECAST
COULD BE A LITTLE OVERDONE. BY 72 HOURS THE CYCLONE SHOULD BE
REACHING COLDER WATERS.

THE INITIAL MOTION REMAINS UNCERTAIN BUT IS ESTIMATED TO BE 340/3.
WATER VAPOR IMAGERY SHOWS A MID- TO UPPER-LEVEL TROUGH EXTENDING
SOUTHWESTWARD FROM THE WESTERN GULF OF MEXICO...AND THIS TROUGH MAY
BE CONTRIBUTING TO THE RELATIVELY WEAK STEERING CURRENT. MODEL
GUIDANCE SUGGESTS THAT THIS TROUGH SHOULD WEAKEN...AND THAT WITHIN
THE NEXT 24-36 HOURS THE DOMINANT STEERING FEATURE SHOULD BE A
RIDGE OF HIGH PRESSURE OVER WESTERN MEXICO. THIS SHOULD GRADUALLY
BEND THE TRACK OF THE CYCLONE TO THE NORTHWEST AND THEN THE
WEST-NORTHWEST. UNCLEAR AT THIS POINT IS HOW CLOSE TO THE CLOSE
THE CENTER WILL GET. GIVEN THE FORECAST TRACK AND WIND RADII...THE
POSSIBILITY EXISTS FOR TROPICAL STORM FORCE WINDS ALONG THE COAST
AND CONSEQUENTLY A TROPICAL STORM WATCH IS BEING ISSUED AT THIS
TIME.

RAINS FROM THE DEPRESSION ARE ALREADY AFFECTING PORTIONS OF THE
WATCH AREA.

I've set up the S2K Worldwide Tropical Update to display links for Calvin. Also, I've fixed the NRL Storm Floaters for Calvin. (NRL changed their directories which threw off the link.)

TROPICAL STORM CALVIN DISCUSSION NUMBER 3
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2 AM PDT MON JUN 27 2005

THE INITIAL POSITION IS BASED MAINLY ON CONTINUITY WITH THE PREVIOUS
FORECAST TRACK AND EXTRAPOLATION OF MICROWAVE SATELLITE POSITIONS
BETWEEN 00Z AND 05Z. A 27/0449Z AMSU OVERPASS INDICATED THE
LOW-LEVEL CIRCULATION REMAINS TO THE SOUTHEAST OF THE MAIN
CONVECTIVE CLOUD MASS AND THE WELL-DEFINED MID-LEVEL CIRCULATION
CENTER. THE INTENSITY OF 35 KT AND THE DECISION TO NAME THE SYSTEM
TROPICAL STORM CALVIN WAS BASED ON A CONSENSUS DVORAK SATELLITE
CURRENT INTENSITY ESTIMATE OF T2.5/35 KT FROM TAFB...SAB...AND
AFWA...PLUS A UW-CIMSS 3-HR AVERAGE AODT ESTIMATE OF T2.6/36 KT.

THE INITIAL MOTION ESTIMATE IS NOW 330/04. THERE IS NO SIGNIFICANT
CHANGE TO THE REASONING OF THE TWO PREVIOUS FORECAST TRACK
DISCUSSIONS. NHC MODEL GUIDANCE REMAINS REASONABLY CONSISTENT ON
GRADUALLY BUILDING THE MEXICAN SUBTROPICAL RIDGE WESTWARD OVER THE
NEXT 2-3 DAYS...WHICH SHOULD ACT TO TURN CALVIN NORTHWESTWARD LATER
TODAY AND THEN MORE WEST-NORTHWESTWARD AFTER 24 HOURS...ALONG WITH
A GRADUAL INCREASE IN FORWARD SPEED UP TO ABOUT 10 KT. CALVIN IS
EXPECTED TO REACH NEAR-26C SSTS BY 72 HOURS AND SLOWLY BEGIN TO
WEAKEN...AND THEN BE FORCED WESTWARD BY THE LOW-LEVEL EASTERLIES.

THE ENVIRONMENT SURROUNDING CALVIN IS STRIKINGLY SIMILAR TO THAT OF
TS BEATRIZ JUST A FEW DAYS AGO. ANOTHER STRONG CONVECTIVE BURST
WENT OFF NORTHWEST OF THE LOW-LEVEL CENTER BETWEEN 03Z-06Z...BUT
HAS SINCE WEAKENED. OTHER BURSTS WILL LIKELY CONTINUE FOR THE NEXT
FEW DAYS...WITH EACH ONE SLIGHTLY STRENGTHENING THE CYCLONE.
HOWEVER...25 TO 30 KT 300-200 MB EASTERLY WINDS HAVE BEEN AND WILL
LIKELY CONTINUE TO UNDERCUT THE OTHERWISE FAVORABLE OUTFLOW LAYER
AND PRODUCE AT LEAST 15-20 KT OF SHEAR. THE GFDL MODEL IS MUCH
LESS ROBUST THAN ITS PREVIOUS RUNS AND NOW ONLY BRINGS CALVIN UP TO
56 KT IN 24 HOURS. SINCE THIS IS SIMILAR TO THE SHIPS MODEL...THE
INTENSITY FORECAST HAS BEEN TRIMMED BACK SLIGHTLY.

HEAVY RAINS FROM CALVIN ARE ALREADY AFFECTING PORTIONS OF THE
TROPICAL STORM WATCH AREA. SINCE THE CURRENT FORECAST KEEPS ANY
TROPICAL STORM FORCE WINDS JUST OFFSHORE...THE EXISTING WATCH
SHOULD SUFFICE FOR THIS FORECAST PACKAGE.

HEAVY RAINS AFFECTING COASTAL MEXICO NEAR ACAPULCO...

A TROPICAL STORM WATCH REMAINS IN EFFECT FROM LAGUNAS DE CHACAHUA
WESTWARD TO LAZARO CARDENAS. A TROPICAL STORM WATCH MEANS THAT
TROPICAL STORM CONDITIONS ARE POSSIBLE WITHIN THE WATCH
AREA...GENERALLY WITHIN 36 HOURS.

FOR STORM INFORMATION SPECIFIC TO YOUR AREA...INCLUDING POSSIBLE

TROPICAL STORM CALVIN DISCUSSION NUMBER 4
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 AM PDT MON JUN 27 2005

ON SATELLITE IMAGES...THE ORGANIZATION OF THE DEEP CONVECTION IS NOT
IMPRESSIVE AT THIS TIME. HOWEVER...RADAR IMAGES FROM THE COMISION
NACIONAL DEL AGUA ACAPULCO REVEAL A RATHER WELL-DEFINED SPIRAL RAIN
BAND STRUCTURE. THE INTENSITY IS INCREASED TO 45 KT FOR THIS
ADVISORY IN AGREEMENT WITH THE LATEST DVORAK ESTIMATES. CALVIN IS
IN A MODERATE EASTERLY SHEAR ENVIRONMENT...SO ONLY SLOW
STRENGTHENING IS EXPECTED. THE OFFICIAL WIND SPEED FORECAST IS
SIMILAR TO THAT FROM THE PREVIOUS PACKAGE AND IS IN GENERAL
AGREEMENT WITH THE SHIPS GUIDANCE. BY 72 HOURS...THE CYCLONE WILL
BEGIN TO MOVE OVER COOLER WATERS...SO WEAKENING IS PROBABLE AFTER
THAT TIME.

CALVIN HAS BEGUN TO TURN TOWARD THE LEFT AND THE MOTION ESTIMATE IS
NOW 310/7. SYNOPTIC REASONING FOR THE TRACK FORECAST IS ABOUT THE
SAME AS IN THE PREVIOUS ADVISORY. A MID-LEVEL RIDGE TO THE NORTH
OF THE TROPICAL CYCLONE SHOULD INDUCE A MOSTLY WEST-NORTHWESTWARD
MOTION UNTIL LATE IN THE PERIOD...WHEN A MORE WESTWARD TRACK OF THE
WEAKENING CYCLONE...FOLLOWING THE LOW-LEVEL EASTERLIES...IS LIKELY.

THE LEFTWARD TURN REDUCES THE THREAT TO THE COAST...AND IF A MORE
WEST-NORTHWESTWARD MOTION IS ESTABLISHED...THE TROPICAL STORM WATCH
COULD BE DISCONTINUED LATER TODAY. LOCALLY HEAVY RAINFALL IS
EXPECTED TO CONTINUE TO AFFECT PORTIONS OF THE SOUTHERN COAST OF
MEXICO TODAY.
