WPAC: TROPICAL STORM KROVANH (0911/12W)

[HURAKAN]

WTPN21 PGTW 272000
MSGID/GENADMIN/NAVMARFCSTCEN PEARL HARBOR HI/JTWC//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 20.7N 148.6E TO 24.0N 145.4E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 22 TO 27 KNOTS. METSAT IM-
AGERY AT 271730Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 21.1N 148.2E. THE SYSTEM IS MOVING NORTHWESTWARD AT 08 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 20.5N
148.7E, IS NOW LOCATED NEAR 21.1N 148.2E, APPROXIMATELY 435 NM EAST-
SOUTHEAST OF IWO TO, JAPAN. RECENT ANIMATED ENHANCED INFRARED
IMAGERY SHOWS DEEP CONVECTION CONTINUES TO DEVELOP OVER THE LOW
LEVEL CIRCULATION CENTER (LLCC) WITH THE DEEPEST CONVECTION ON THE
SOUTHERN HALF OF THE LLCC ASSOCIATED WITH CONVERGENCE. A 271617Z
TRMM 85H IMAGE SUPPORTS THE TIGHT TURNING WITH THE DEEPEST
CONVECTION EXTENDING TO THE SOUTHWEST. UPPER LEVEL ANALYSIS DEPICTS
A FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT, WITH MULTIPLE
OUTFLOW CHANNELS OVER THE SYSTEM. A TROPICAL UPPER TROPOSPHERIC
TROUGH CELL HAS DEVELOPED AROUND 26.1N 146.3E AND HAS HELPED TO
ENHANCE THE POLEWARD OUTFLOW CHANNEL. A TROUGH NEAR 22.7N 163.0E HAS
CONTINUED TO ALLOW GOOD OUTFLOW TO THE EAST. SOUTH OF THE LLCC UPPER
LEVEL EASTERLY FLOW HAS CONTINUED TO MAINTAIN AN EQUATORWARD OUTFLOW
CHANNEL. WITH LOW VERTICAL WIND SHEAR AND FAVORABLE SEA SURFACE
TEMPERATURES FURTHER DEVELOPMENT OF THIS SYSTEM IS EXPECTED TO
CONTINUE. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 22 TO 27
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
282000Z.//

Looking good

[cycloneye]

HURAKAN,what will be the name if this develops into a storm?

[StormingB81]

Hello everyone just started mya ccount I found this site a couple days ago and I was like AWESOME! Anyways I am in Okinawa so this better get a good punch and come here I havent been in a good stormin a loong time.

[RL3AO]

Welcome.

[bombarderoazul]

I think the next name on the list is Krovanh

[StormingB81]

I hate waiting on storms to develop and out here in Japan it seems hard sometimes to get updates. I know that have the JTWC and KMA. and of course here at Storm2K. But does anyone know anysites that I can get updates from?

[HURAKAN]

Code: Select all

column IV     Meaning     Contributed by
Krovanh    A kind of tree    Cambodia

LOW PRESSURE AREA 1004 HPA NEAR 21N 149E ALMOST STATIONARY.

[StormingB81]

It is now a depression!!!!

[Chacor]

This formed in a hurry.

27/1700Z: JTWC upgrades formation potential from "poor" to "fair".
27/2000Z: JTWC issues TCFA and upgrades formation potential from "fair" to "good".
28/0000Z (0300Z): JTWC issues first warning on Tropical Depression 12W.

[StormingB81]

I am looking the first projected path I bet you it hits closer to Okinawa and is more then a tropical storm when it hits..Im guessing it will come ashore probably on the 2nd wit habout 100-110mph sustained winds. water is warmer.

REMARKS:
280900Z POSITION NEAR 23.0N 148.2E.
TROPICAL STORM (TS) 12W, LOCATED APPROXIMATELY 410 NM EAST-
SOUTHEAST OF IWO TO, HAS TRACKED NORTHWARD AT 07 KNOTS OVER THE PAST
SIX HOURS. THE SYSTEM HAS INTENSIFIED TO NEAR 40 KNOTS BASED ON A
DVORAK SATELLITE INTENSITY ESTIMATE FROM PGTW INDICATING A SYSTEM AS
INTENSE AS 45 KNOTS. DEEP CONVECTION CONTINUES TO BUILD IN OVER THE
LOW LEVEL CIRCULATION CENTER WITH NUMEROUS VENTING MECHANISMS ALOFT.
THE STORM IS TRACKING SLIGHTLY NORTH OF NORTHWEST ALONG THE WESTERN
PERIPHERY OF THE MID-LEVEL SUBTROPICAL RIDGE. BECAUSE MODEL GUIDANCE
IS STILL LIMITED, THIS FORECAST CLOSELY FOLLOWS THE FIRST WARNING.
HOWEVER, MAXIMUM INTENSITY HAS BEEN INCREASED TO 70 KNOTS IN
RESPONSE TO AN INCREASE IN INTENSITY FORECAST GUIDANCE. RIDGING IS
STILL EXPECTED TO BUILD FROM EAST TO WEST OVER THE SYSTEM,
PROGRESSIVELY BENDING THE FORECAST TRACK INCREASINGLY WESTWARD
THROUGHOUT THE FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
280600Z IS 12 FEET. NEXT WARNINGS AT 281500Z, 282100Z, 290300Z AND
290900Z.

Looking quite good

[apocalypt-flyer]

This could do quite some damage. And it wouldn't completely surprise me if JTWC underestimate the future strength of what's going to be Krovanh.

[Chacor]

Of what is Krovanh.

JMA's got a much slower intensification forecast.
