INVEST 92W upgraded to MEDIUM for the next 24 hours by the JTWC

2019 Feb 17 13h48UTC WESTERN NORTH PACIFIC

1: Invest 92W is already upgraded to MEDIUM at 13UTC.  A 12UTC it was located approx 2635km to the south-east of Guam.

2: here is the latest ABPW bulletin from the Navy:
ABPW10 PGTW 171300
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 2.2N 166.4E, IS NOW LOCATED NEAR 3.4N 166.5E, APPROXIMATELY 237
NM EAST-SOUTHEAST OF KOSRAE. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS A FLARING CONVECTION OBSCURING A CONSOLIDATING LOW
LEVEL CIRCULATION (LLC) WITH FORMATIVE BANDING BEGINNING TO WRAP IN.
A 170712Z WINDSAT 37GHZ SHOWS A LARGE AREA OF CONVECTION EXTENDING
NORTH FROM THE LLC WITH FORMATIVE MID-LEVEL BANDIND. A 171040Z METOP-
B ASCAT PASS SHOWS AN ELONGATED CIRCULATION WITH A SMALL SWATH OF 20
KNOT WIND BARBS TO THE NORTH OF THE LLC. 92W IS CURRENTLY IN A
FAVORABLE ENVIRONMENT WITH EXCELLENT WESTWARD OUTFLOW, LOW (10 TO 15
KNOT) VERTICAL WIND SHEAR, AND VERY WARM (29 TO 31 CELSIUS) SEA
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 92W
WILL TRACK WESTWARD WITH MINIMAL INTENSIFICATION BEFORE CURVING TO
THE NORTH AND BEGINNING QUICKER INTENSIFICATION. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.
