Tropical Depression Kiko in EPac

[Kiko]

Had to stop in to say hello. Wow, a storm named after me! I'm deeply honored.

[AZRainman]

Kiko needs to visit the desert southwest US, cause we forgot what the rain looks like out here.

Anyone thinking it will reach cat 1? Nice map Chad, looking more pro all the time.

[chadtm80]

Kiko!! Long time no see!! Been thinking about you all week with this thin churning out there..

Thanks azrainman

[Kiko]

Still kicking... if I dare to state the obvious.

Nice to see you too, Chad ...and Cy.

Hi Kiko,long time without seeing you around here.

TROPICAL STORM KIKO DISCUSSION NUMBER 13
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP152007
800 PM PDT WED OCT 17 2007

NEW THUNDERSTORM CLUSTERS HAVE FIRED NEAR THE CENTER OF KIKO AFTER
IT WAS EXPOSED FOR A FEW HOURS THIS AFTERNOON. HOWEVER...THIS
SYSTEM STILL HAS A RATHER ELONGATED SHAPE AND IT IS UNKNOWN HOW
SEPARATE THE TROPICAL CYCLONE IS FROM THE ITCZ. THERE HAVE BEEN NO
CHANGES TO THE SATELLITE CLASSIFICATIONS...AND THE INITIAL
INTENSITY WILL REMAIN 35 KT. GLOBAL MODELS SUGGEST THAT THE
MODERATE TO STRONG EASTERLY SHEAR THAT HAS BEEN AFFECTING THIS
SYSTEM WILL ABATE IN A DAY OR TWO WHICH...ASSUMING THE SYSTEM
SURVIVES...WOULD ALLOW FOR SOME STRENGTHENING. IN FACT THE
SHIPS/HWRF/GFDL MODELS SHOW THIS SYSTEM BECOMING A HURRICANE BY THE
END OF THE FORECAST PERIOD. GIVEN THE DISHEVELED PATTERN ON
SATELLITE...I WOULD PREFER TO WAIT UNTIL THE STORM SHOWS MORE SIGNS
OF ORGANIZATION BEFORE JUMPING ON THE HURRICANE KIKO BANDWAGON.
HOWEVER THE OFFICIAL FORECAST IS NUDGED UPWARDS AT DAYS 3-5 IN
DEFERENCE TO OUR BEST INTENSITY GUIDANCE.

THE INITIAL MOTION ESTIMATE IS 070/7...WHICH INDICATES A SMALL TURN
TOWARD THE LEFT IN THE LAST SIX HOURS. KIKO APPEARS TO BE CAUGHT
UP IN LOW-LEVEL WEST TO SOUTHWESTERLY FLOW ASSOCIATED WITH THE
ITCZ. THIS PATTERN IS NOT EXPECTED TO LAST FOR MORE THAN A DAY OR
SO DUE TO A BUILDING MIDDLE-LEVEL RIDGE OVER MEXICO. THIS RIDGE
SHOULD FORCE THE STORM TO TURN LEFTWARD WITH TIME AND CAUSE A MORE
NORTHWESTWARD MOTION IN A COUPLE DAYS. HOWEVER...THE BIG QUESTION
IS WHETHER THE STORM WILL BE TOO CLOSE BY THEN TO MISS MEXICO.
MOST MODELS HAVE SHIFTED EASTWARD COMPARED TO SIX HOURS AGO...
ESPECIALLY THE 18Z UKMET MODEL RUN. THE ECMWF/GFDN/NOGAPS/UKMET
MODELS ALL SHOW THE SYSTEM MOVING OVER OR CLOSE TO MEXICO DURING
THE FORECAST PERIOD. THE OFFICIAL FORECAST IS A BLEND OF THOSE
GLOBAL MODELS AND THE PREVIOUS ADVISORY...SHOWING SOME THREAT TO
MEXICO IN A COUPLE OF DAYS. WATCHES MAY HAVE TO BE ISSUED
TOMORROW...PARTICULARLY IF THIS EASTWARD SHIFT IN THE MODEL
GUIDANCE CONTINUES.

Sorry if this has been posted, but have ya seen the 18Z GFDL for Kiko? Look at what it spins up in the BOC!!!!

http://moe.met.fsu.edu/cgi-bin/gfdltc2. ... =Animation

Wow...looks like a twin to the CMC model with here-a-cane, there-a-cane...

Might be something to watch since the CMC in fact does show something in that neck of the woods...

That's no twin, that's a little brother...

TROPICAL STORM KIKO DISCUSSION NUMBER 14
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP152007
200 AM PDT THU OCT 18 2007

SATELLITE IMAGERY INDICATES THAT KIKO IS EMBEDDED WITHIN A BROAD
AREA OF CYCLONIC FLOW ASSOCIATED WITH THE ITCZ. THE LOW LEVEL
CIRCULATION IS DIFFICULT TO LOCATE IN INFRARED SATELLITE IMAGERY
AND THE INITIAL MOTION RELIES HEAVILY ON EXTRAPOLATION. WHILE
CONVECTION APPEARS A LITTLE BETTER ORGANIZED...DVORAK
CLASSIFICATIONS ARE UNCHANGED AND SO IS THE INITIAL INTENSITY.
KIKO CONTINUES TO EXPERIENCE MODERATE EASTERLY SHEAR WHICH HAS THUS
FAR LIMITED STRENGTHENING. HOWEVER...GLOBAL MODELS SUGGEST THAT
THE SHEAR WILL RELAX OVER THE NEXT COUPLE OF DAYS. ASSUMING THE
CYCLONE SURVIVES...ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR
SOME STRENGTHENING. IN FACT THE SHIPS/HWRF/GFDL MODELS ALL SHOW
KIKO BECOMING A HURRICANE. GIVEN THE RATHER BROAD CIRCULATION AND
THE CURRENT LACK OF ORGANIZATION...THE OFFICIAL INTENSITY FORECAST
IS BELOW THE GUIDANCE AND MAINTAINS KIKO AS A TROPICAL STORM.

THE INITIAL MOTION ESTIMATE IS 060/6. THE TRACK FORECAST HINGES ON
WHETHER OR NOT KIKO CAN BREAK FREE FROM THE LOW-LEVEL SOUTHWESTERLY
FLOW ASSOCIATED WITH THE ITCZ. IF THE CYCLONE REMAINS WEAK AND
POORLY DEFINED...IT COULD CONTINUE NORTHEASTWARD TOWARD THE COAST
OF MEXICO FOR THE NEXT DAY OR TWO. CONVERSELY...IF THE CYCLONE
WERE TO STRENGTHEN AND BECOME DEEPER...IT WOULD TEND TO BE STEERED
NORTHWESTWARD BY A BUILDING MIDDLE-LEVEL RIDGE OVER MEXICO.
FURTHER COMPLICATING THE TRACK FORECAST IS THE POSSIBILITY OF LAND
INTERACTION AS THE CYCLONE APPROACHES THE SOUTHWEST COAST OF
MEXICO. SINCE THE GLOBAL MODELS TEND TO HAVE A WEST BIAS IN CASES
WHERE CYCLONES MOVE CLOSE TO THE COAST OF MEXICO...THE OFFICIAL
FORECAST IS SHIFTED A LITTLE TO THE EAST AND IS RIGHT OF THE MODEL
CONSENSUS. INTERESTS ALONG THE SOUTHWEST COAST OF MEXICO SHOULD
CLOSELY MONITOR THE PROGRESS OF THIS SYSTEM AS WATCHES AND/OR
WARNINGS MAY BE REQUIRED LATER TODAY.

TROPICAL STORM KIKO DISCUSSION NUMBER 15
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP152007
800 AM PDT THU OCT 18 2007

SATELLITE IMAGERY THIS MORNING SHOWS THAT KIKO IS A LITTLE BETTER
ORGANIZED THAN 24 HR AGO...WITH A LESS ELONGATED LOW-LEVEL
CIRCULATION. EASTERLY VERTICAL WIND SHEAR HAS DECREASED OVER THE
PAST 24 HR...WHICH HAS ALLOWED THE CENTER TO BECOME MORE INVOLVED
WITH THE CONVECTION. HOWEVER...THE SYSTEM STILL APPEARS SOMEWHAT
RAGGED...AND BASED ON THIS AND UNCHANGED SATELLITE INTENSITY
ESTIMATES THE INITIAL INTENSITY REMAINS 35 KT.

THE CENTER OF KIKO MOVED FASTER DURING THE NIGHT...AND THE INITIAL
MOTION ESTIMATE IS 040/8. ALL GUIDANCE AGREES THAT THE FORWARD
SPEED SHOULD SLOW DURING THE NEXT 24-48 HR AS PRESSURES RISE OVER
NORTHERN MEXICO IN THE WAKE OF THE EASTWARD-MOVING DEEP-LAYER TROUGH
OVER THE UNITED STATES...ACCOMPANIED BY THE CENTER TURNING TO THE
NORTH AND NORTHWEST NEAR OR OVER THE PACIFIC COAST OF MEXICO.
AFTER 48 HR...A SECOND DEEP-LAYER TROUGH DEVELOPS OVER THE CENTRAL
AND WESTERN U.S. THE LARGE-SCALE MODELS CONTINUE TO DISAGREE ON
THE EVOLUTION OF THIS TROUGH AND ITS EFFECTS ON KIKO. THE ECMWF
AND NOGAPS FORECAST THE TROUGH TO AMPLIFY FARTHER TO THE WEST...
WITH KIKO TURNING NORTHWARD INTO MAINLAND MEXICO. THE UKMET AND
GFS FORECAST THE TROUGH TO AMPLIFY FARTHER TO THE EAST...WITH
RIDGING BUILDING NORTH OF KIKO CAUSING A WESTWARD TRACK INTO THE
OPEN PACIFIC. RIGHT NOW...IT CANNOT BE DETERMINED WHICH OF THESE
EXTREMES WILL BE RIGHT...SO THE FORECAST TRACK WILL COMPROMISE
BETWEEN THEM WITH A CONTINUED SLOW MOTION TOWARD THE NORTHWEST.

UPPER-LEVEL WINDS HAVE BECOME MORE FAVORABLE FOR DEVELOPMENT...WITH
THE LARGE-SCALE MODELS FORECASTING THEM TO REMAIN FAVORABLE FOR AT
LEAST THE NEXT 48-72 HR. THIS SHOULD ALLOW STRENGTHENING...WITH
THE MAIN NEGATIVE FACTOR BEING THE PROXIMITY TO LAND. THE NEW
INTENSITY FORECAST CALLS FOR FASTER INTENSIFICATION THEN THE
PREVIOUS FORECAST...WITH KIKO REACHING A 55 KT INTENSITY BEFORE THE
CENTER BRUSHES THE COAST OF MEXICO IN ABOUT 72 HR. KIKO COULD
BECOME A HURRICANE IF THE CENTER STAYS FARTHER OFFSHORE...AS
INDICATED BY THE GFDL MODEL.

THE CURRENT POSITION AND NEW FORECAST TRACK REQUIRE WARNINGS AND
WATCHES FOR PORTIONS OF THE COAST OF MEXICO AT THIS TIME.

NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP152007
200 PM PDT THU OCT 18 2007

AFTERNOON SATELLITE IMAGERY INDICATES THAT KIKO IS GRADUALLY
BECOMING BETTER ORGANIZED...WITH INCREASING CONVECTIVE BANDS NEAR
THE CENTER AND IMPROVING CIRRUS OUTFLOW. THE BANDING HAS NOT YET
INCREASED ENOUGH TO RAISE THE SATELLITE INTENSITY ESTIMATES...SO
THE INITIAL INTENSITY REMAINS 35 KT. THE LATEST ANALYSIS FROM
CIMSS AT THE UNIVERSITY OF WISCONSIN NOW SHOW ABOUT 15 KT OF
EASTERLY VERTICAL WIND SHEAR AFFECTING THE STORM.

THE CENTER IS STILL BROAD AND HARD TO PIN DOWN EVEN WITH MICROWAVE
IMAGERY...BUT IT MAY BE A LITTLE WEST OF THE POSITION IN PREVIOUS
ADVISORY. THE INITIAL MOTION IS NOW A SOMEWHAT UNCERTAIN 360/3.
IN THE FIRST 48 HR OR SO...KIKO SHOULD MOVE SLOWLY NORTHWARD TO
NORTHWESTWARD AS PRESSURES RISE OVER NORTHERN MEXICO IN THE WAKE OF
AN EASTWARD-MOVING DEEP-LAYER TROUGH OVER THE CENTRAL UNITED
STATES. AFTER 48 HR...UNCERTAINTY REMAINS REGARDING THE HANDLING OF
A SECOND TROUGH OVER THE WESTERN AND CENTRAL U.S. THE GFS
CONTINUES TO BUILD ENOUGH RIDGE BETWEEN KIKO AND THE TROUGH TO TURN
THE STORM WESTWARD. IN A NOTABLE CHANGE FROM ITS PREVIOUS RUN...
THE ECMWF NOW SHOWS MORE RIDGING NORTH OF KIKO AND A NORTHWESTWARD
TO WESTWARD MOTION SIMILAR TO THE GFS. THE UKMET CONTINUES TO
BUILD THE RIDGE AFTER 48 HR...BUT IN A TWIST MOVES THE STORM
NORTHWARD INTO MEXICO BEFORE THE RIDGE BUILDS IN. THE NOGAPS
AMPLIFIES THE TROUGH INTO THE SOUTHWESTERN U.S. IN A PATTERN THAT
WOULD CAUSE A NORTHWARD MOTION INTO MEXICO. THE GFDL AND HWRF CALL
FOR A GENERALLY NORTHWESTWARD MOTION AT A MUCH FASTER SPEED THAN
THE OTHER MODELS. THE NEW FORECAST TRACK WILL BE SIMILAR TO BUT
LEFT OF THE PREVIOUS FORECAST FOR THE FIRST 48 HR. AFTER THAT...IT
CALLS FOR A GRADUAL BEND TOWARD THE WEST-NORTHWEST IN RESPONSE TO
THE BUILDING RIDGE. THIS PART OF THE TRACK IS LEFT OF AND SOMEWHAT
FASTER THAN THE PREVIOUS FORECAST...AT ABOUT THE SPEED OF THE ECMWF
AND THE FSU SUPERENSEMBLE.

UPPER-LEVEL WINDS HAVE BECOME MORE FAVORABLE FOR DEVELOPMENT...WITH
THE LARGE-SCALE MODELS FORECASTING THEM TO REMAIN FAVORABLE FOR AT
LEAST THE NEXT 48-72 HR. SINCE KIKO IS FORECAST TO REMAIN FARTHER
FROM LAND...THE FORECAST INTENSITIES HAVE BEEN SIGNIFICANTLY
INCREASED FROM THE PREVIOUS ADVISORY. THE NEW INTENSITY FORECAST
CALLS FOR KIKO TO BECOME A HURRICANE IN 36-48 HR...AND THEN PEAK AT
ABOUT 96 HR AS IT ENCOUNTERS INCREASING SHEAR. THE NEW INTENSITIES
ARE HIGHER THAN THOSE OF THE SHIPS MODEL...BUT BELOW THOSE OF THE
GFDL...HWRF...AND THE INTENSITY CONSENSUS.

Kiko needs to visit the desert southwest US, cause we forgot what the rain looks like out here.
