SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 93P)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
100 NM EITHER SIDE OF A LINE FROM 10.2S 155.8E TO 12.3S 157.0E
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 20 TO 25 KNOTS. METSAT
IMAGERY AT 091800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 10.6S 155.9E. THE SYSTEM IS MOVING SOUTHWARD AT 10 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 93P) PREVIOUSLY LOCATED
NEAR 10.4S 155.0E IS NOW LOCATED NEAR 10.6S 155.9E, APPROXIMATELY
250NM WEST-SOUTHWEST OF HONIARA, SOLOMON ISLANDS. ANIMATED ENHANCED
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 091729Z SSMIS 91GHZ
MICROWAVE IMAGE DEPICT A LOW-LEVEL CIRCULATION CENTER WITH DEEP
CONVECTION TO THE NORTHERN PERIPHERY. IN ADDITION, FORMATIVE BANDING
WRAPS INTO THE CENTER TO THE WEST AND SOUTH. ENVIRONMENTAL ANALYSIS
INDICATES FAVORABLE CONDITIONS FOR DEVELOPMENT WITH STRONG POLEWARD
OUTFLOW, WEAK (05-10KTS) VERTICAL WIND SHEAR, AND VERY WARM (30-31C)
SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT ON THAT 93P
WILL TRACK EAST-SOUTHEAST AND CONTINUE TO INTENSIFY TO TROPICAL
DEPRESSION STRENGTH OVER THE NEXT 24-48 HOURS.  MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 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 HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
102130Z.

(1) THE AREA OF CONVECTION (INVEST 93P) PREVIOUSLY LOCATED
NEAR 9.7S 156.2E IS NOW LOCATED NEAR 10.4S 155.0E, APPROXIMATELY 468
NM EAST OF PORT MORESBY, PAPUA NEW GUINEA. ANIMATED ENHANCED
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 090312Z AMSR2 89GHZ
MICROWAVE IMAGE DEPICT DISORGANIZED FLARING CONVECTION WRAPPING INTO
A BROAD LOW LEVEL CIRCULATION (LLC). ENVIRONMENTAL ANALYSIS REVEALS
THAT THE CIRCULATION IS IN AN AREA OF MARGINALLY FAVORABLE
DEVELOPMENT DEFINED BY WARM SST (30-31C) AND LOW TO MODERATE
VERTICAL WIND SHEAR. THE OUTFLOW IS NOTABLE WITH ENHANCED POLEWARD
OUTFLOW FEEDING INTO THE JET TO THE SOUTH. GLOBAL MODELS ARE IN
AGREEMENT THAT THE SYSTEM WILL GENERALLY TRACK SOUTHEASTWARD AND
CONTINUE TO DEVELOP OVER THE NEXT 24-48 HOURS. 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 UPGRADED TO MEDIUM.

(1) AN AREA OF CONVECTION (INVEST 93P) HAS PERSISTED NEAR 9.7S
156.2E, APPROXIMATELY 225 NM WEST OF HONIARA, SOLOMON ISLANDS.
ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY DISPLAYS LOW LEVEL
CLOUD LINES WRAPPING INTO A BROAD LLCC (LOW LEVEL CIRCULATION
CENTER) WITH FLARING, DISORGANIZED CONVECTION. A 072251Z METOP-C
PASS SHOWS 10-15KT WINDS AROUND A LARGE CIRCULATION CENTER.
ENVIRONMENTAL ANALYSIS REVEALS THAT THE CIRCULATION IS IN AN AREA OF
MARGINALLY FAVORABLE DEVELOPMENT DEFINED BY WARM SST (30-31C) AND
LOW TO MODERATE VERTICAL WIND SHEAR. THE OUTFLOW IS NOTABLE WITH
ENHANCED POLEWARD OUTFLOW FEEDING INTO THE JET TO THE SOUTH. GLOBAL
MODELS ARE IN AGREEMENT THAT THE SYSTEM WILL GENERALLY TRACK
SOUTHEASTWARD OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
