THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.0N
142.0E, IS NOW LOCATED NEAR 15.1N 137.1E, APPROXIMATELY 390 NM WEST-
NORTHWEST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS
A BROAD AREA OF FLARING CONVECTION EMBEDDED WITHIN THE MONSOON
TROUGH. UPPER-LEVEL ANALYSIS INDICATES THAT THE SYSTEM LIES WELL
EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS, IN AN AREA OF MODERATE
(15 TO 20 KNOT) NORTHEASTERLY VERTICAL WIND SHEAR. A 101036Z SSMIS
91 GHZ MICROWAVE IMAGE SHOWS A BROAD AREA OF SCATTERED,
DISORGANIZED CONVECTION WITH NO DISCERNABLE LOW-LEVEL CIRCULATION
CENTER (LLCC) TO SPEAK OF. A 100009Z PARTIAL ASCAT PASS INDICATES A
BROAD AREA OF SHARP TROUGHING, BUT IS INSUFFICIENT IN DETERMINING
IF THE DISTURBANCE IS A CLOSED CIRCULATION AT THIS POINT. SEA
SURFACE TEMPERATURES IN THE AREA REMAIN A FAVORABLE 27 TO 29
DEGREES CELSIUS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

It seems that this system actually tracking more west. oh, another threat to unfold for Philippines. People here are still in many evacuation centers due to extensive floods brought by SWMS during early days of the week.

God is the blessing Philippines!

having bad flashbacks of Ketsana and Parma. :( Ketsana did the flooding, then there came Parma even before people could recover. just this time, it was the monsoon without a real storm that caused the floods and then there's this system that doesn't want to give a break.

anyway, this tropical disturbance seems to be composed by multiple vortices just like the previous storms that we had. seems to be spinning up and heading west but the models say this is gonna pass somewhere between Batanes islands and Taiwan as a weak system...but that's what they say as of now. Whatever happens, I'll be watching this thing closely until it's gone.

well defined LLC with bandings developing...coulkd this become our 14th tropical cyclone?

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.4N
134.3E, IS NOW LOCATED NEAR 16.0N 134.0E, APPROXIMATELY 455 NM
NORTH-NORTHWEST OF YAP. ANIMATED ENHANCED INFRARED IMAGERY DEPICTS
PERSISTENT DEEP CONVECTION WITHIN AN AREA OF BROAD TURNING
ASSOCIATED WITH THE MONSOON TROUGH. A 111458Z OSCAT PASS REVEALS A
WELL DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) WITH LIGHT (10 KT)
WINDS IN THE EASTERN SEMI-CIRCLE AND 15-20 KT WINDS IN THE LARGELY
RAIN-FLAGGED WESTERN SEMI-CIRCLE. A 111420Z PARTIAL TRMM PASS
REVEALS LOOSELY ORGANIZED CONVECTION WITH WEAK FORMATIVE BANDING.
UPPER-LEVEL ANALYSIS INDICATES THE SYSTEM LIES APPROXIMATELY FIVE
DEGREES EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS IN AN AREA OF
LIGHT TO MODERATE (10 TO 15 KNOT) NORTHEASTERLY VERTICAL WIND SHEAR
(VWS). SEA SURFACE TEMPERATURES IN THE AREA REMAIN A FAVORABLE 27 TO
29 DEGREES CELSIUS. NUMERICAL GUIDANCE INDICATES THIS AREA WILL
CONTINUE TO CONSOLIDATE AS VWS RELAXES AND OUTFLOW IMPROVES,
REACHING TROPICAL DEPRESSION STRENGTH IN THE NEXT 36-48 HOURS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1009 MB. DUE TO
THE WELL DEFINIED LLCC AND IMPROVING ENVIRONMENTAL CONDITIONS, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.

...also the same month of August, that super typhoon was quite memorable for me that year..Sepat also dumped lots of rain across Luzon too via enhanced monsoon.

Right now monsoon is no fun for the Philippines, I wonder if this system will also be a rainmaker in the coming days.
