WPAC: Tropical Depression (INVEST 95W)

[Chacor]

Still a TD, I don't know why the topic title claims it's an ex-TD.

06z:
TROPICAL DEPRESSION 1004 HPA AT 23N 138E WEST 10 KT.

Chacor, because this was temporarily dropped as a TD from JMA's weather map, because the attention shifted to Nanmadol and the developing area near Guam (97W) and frankly because this hasn't had sufficient convection for days to get excited about it (otherwise you would've noted it before now as well). Once something is a TD with JMA, it will stay a TD based on winds alone even without convection, but is IMO would be non-classified in any other basin. (No ASCAT this time to see)

1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 230000Z, TROPICAL DEPRESSION 14W (FOURTEEN) WAS LOCATED
NEAR 15.7N 127.4E, APPROXIMATELY 350 NM EAST OF MANILA, PHILIPPINES,
AND HAD TRACKED NORTH-NORTHWESTWARD AT 06 KNOTS OVER THE PAST SIX
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS
GUSTING TO 40 KNOTS. SEE REF A (WTPN31 PGTW 230300) FOR FURTHER
DETAILS.
(2) NO OTHER TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.7N
142.8E IS NOW LOCATED NEAR 14.6N 143.4E, APPROXIMATELY 105 NM
NORTHWEST OF ANDERSEN AIR FORCE BASE, GUAM. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A BROAD LOW-LEVEL CIRCULATION CENTER
(LLCC) WITH DISORGANIZED DEEP CONVECTION FLARING OVER THE CENTER.
GUAM RADAR IMAGERY AND A 230110Z TRMM IMAGE SHOW A DEVELOPING LLCC
WITH FORMATIVE BANDING WRAPPING AROUND THE CENTER. THE LLCC IS
LOCATED NEAR A DEVELOPING UPPER-LEVEL ANTICYCLONE WITH GOOD
DIFFLUENCE ENHANCED BY A TUTT CELL LOCATED NEAR 20N 165E AND WEAK
VERTICAL WIND SHEAR (10-15 KNOTS). DUE TO THE FAVORABLE ENVIRONMENT,
THE BULK OF THE MODELS INDICATE DEVELOPMENT INTO A TROPICAL
DEPRESSION WITHIN THE NEXT 24-36 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1006 MB. BASED ON THE LACK OF CONVECTIVE
ORGANIZATION AT THIS TIME, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
(2) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 23.1N
142.8E, IS NOW LOCATED NEAR 23.4N 137.8E, APPROXIMATELY 210 NM WEST-
SOUTHWEST OF IWO TO, JAPAN. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A SMALL, FULLY-EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC)
WITH NO ASSOCIATED DEEP CONVECTION. A 230006Z ASCAT IMAGE SHOWS 10-
15 KNOT WINDS SURROUNDING THE CORE WITH 15-20 KNOT WINDS DISPLACED
NORTH OF THE CENTER. THE SYSTEM REMAINS SITUATED WITHIN AN
UNFAVORABLE UPPER-LEVEL ENVIRONMENT ALONG THE EASTERN PERIPHERY OF A
TUTT CELL LOCATED NEAR 25N 132E AND IS UNDER STRONG VERTICAL WIND
SHEAR (25-30 KNOTS). THE LLCC IS ACCELERATING WESTWARD ALONG THE
NORTHERN EDGE OF THE MONSOON GYRE AND THERE IS NO SIGNIFICANT MODEL
DEVELOPMENT EXPECTED. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 10 TO 15 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 REMAINS LOW.
(3) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.//
