LOW PRESSURE AREA 1010 HPA NEAR 13N 115E ALMOST STATIONARY.

[HURAKAN]

AN AREA OF CONVECTION HAS PERSISTED NEAR 14.4N 117.3E,
APPROXIMATELY 215 NM WEST OF MANILA, PHILIPPINES. RECENT ANIMATED
MULTISPECTRAL SATELLITE IMAGERY SHOWS AN ELONGATED LOW LEVEL
CIRCULATION CENTER WITH DEEP CONVECTION NEAR THE CENTER AND BROKEN
CONVECTIVE BANDING WRAPPING INTO THE SOUTHERN PERIPHERY. A 282323Z
TRMM PASS SHOWS DEEP CONVECTIVE BANDING CURVING INTO THE EASTERN
FLANK OF THE SYSTEM WITH BROKEN CONVECTIVE BANDING TO THE SOUTH.
UPPER LEVEL ANALYSIS SHOWS THE SYSTEM IS IN AN AREA OF LOW VERTICAL
WIND SHEAR AND LOCATED UNDER THE UPPER LEVEL RIDGE AXIS. ANIMATED
WATER VAPOR IMAGERY SHOWS GOOD EQUATORWARD OUTFLOW AND POLEWARD
OUTFLOW APPEARS TO BE SUPPRESSED BY SURFACE RIDGING TO THE NORTH.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS FAIR.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 225 NM RADIUS OF 13.6N 117.2E WITHIN THE NEXT 12 TO 24 HOURS.
AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF NUMBERED TROPICAL CY-
CLONE WARNINGS AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO
BE 17 TO 22 KNOTS. METSAT IMAGERY AT 292030Z INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 13.5N 117.2E. THE SYSTEM IS
QUASI-STATIONARY.
2. REMARKS: THE AREA OF OF CONVECTION PREVIOUSLY LOCATED NEAR 14.4N
117.3E IS NOW LOCATED NEAR 13.5N 117.2E, APPROXIMATELY 230 NM
WEST-SOUTHWEST OF MANILA, PHILIPPINES. RECENT ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY AND A 291109Z QUIKSCAT PASS SHOW A LOW
LEVEL CIRCULATION CENTER (LLCC) THAT HAS CONSOLIDATED AND HAS BEGUN
TO INTENSIFY. IT IS CURRENTLY SHOWING THE 15-20 KNOT WINDS AROUND THE
LLCC AND INCREASED CONVECTION DEVELOPING OVER THE LLCC. SEA SURFACE
TEMPERATURES ARE ALSO VERY FAVORABLE FOR CONTINUED DEVELOPMENT. UPPER
LEVEL ANALYSIS INDICATES THAT THE LLCC IS IN A LOW VERTICAL WIND
SHEAR ENVIRONMENT WITH AN UPPER LEVEL ANTICYCLONE LOCATED OVER THE
LLCC. POLEWARD OUTFLOW IS ALSO BEING ENHANCED BY THE ANTICYCLONE,
CREATING A GOOD OUTFLOW CHANNEL. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 17 TO 22 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. DUE TO INCREASED ORGANIZATION OF THE LLCC AND
PERSISTENT DEEP CONVECTION NEAR THE LLCC, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS GOOD.

Woo-hoo! First TC of the WPAC season!

Not exactly, neither JMA or JTWC have commenced warnings.

Oh well, one of those three invests ought to turn into something. This is just about the time of year when the WPAC gets its first typhoon.

1. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.6N
117.6E IS NOW LOCATED NEAR 13.2N 118.0E, APPROXIMATELY 195 NM WEST-
SOUTHWEST OF MANILA, PHILIPPINES. ANIMATED INFRARED SATELLITE IMAGERY
AND A PARTIAL 301717Z AMSU IMAGE (PLUS RECENT MICROWAVE IMAGERY)
INDICATE A WEAKENING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH DIS-
ORGANIZED, ISOLATED DEEP CONVECTIVE BURSTS AS WELL AS A DISTINCT
LACK OF SIGNIFICANT CONVECTIVE BANDING. SATELLITE IMAGERY AND A
RECENT QUIKSCAT IMAGE DEPICT A MORE ELONGATED, WEAKER LLCC WITH 15-
20 KNOT UNFLAGGED WINDS. SHIP REPORTS ALONG BOTH THE WESTERN AND
EASTERN PERIPHERIES INDICATED 10-15 KNOT WINDS WITH SLP NEAR 1006-
1007 MB. THE LLCC IS LOCATED UNDER THE SUBTROPICAL RIDGE AXIS WITH
WEAK VERTICAL WIND SHEAR, HOWEVER, DEVELOPMENT APPEARS TO BE
HINDERED BY THE CLOSE PROXIMITY TO A STRONGER, LARGER SYSTEM OVER
THE CENTRAL PHILIPPINES AS WELL AS SOME DRY AIR ENTRAINMENT
SUGGESTED BY THE LATEST TOTAL PRECIPITABLE WATER PRODUCTS. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS AND MINIMUM
SEA LEVEL PRESSURE AT 1006 MB. BASED ON THE LACK OF CONVECTIVE
ORGANIZATION AND THE PROXIMITY TO A MORE DOMINANT LOW OVER THE
PHILIPPINES, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO POOR.
