WPAC: INVEST 91W

[Extratropical94]

Whooosh, next one!

7.5°N, 139.4°E - 15 kts, 1010 mb

Isn't this near where Songda started? They just seem to have all the same starting points....Nothing develops it yet which could be a good thing.

[Extratropical94]

Yep, it's nearly the same region.
Songda had one of its first positions estimated at 9N 141-143E, quite close to this one here.

i'm liking this threat more over 90W, mainly because it's away from land... low vws and high SSTs as well so we'll see...

AN AREA OF CONVECTION HAS PERSISTED NEAR 7.7N 139.2E,
APPROXIMATELY 120 NM SOUTH-SOUTHEAST OF YAP. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A DEVELOPING LOW LEVEL CIRCULATION CENTER
(LLCC) WITH CONSOLIDATING CENTRAL CONVECTION. A 310050Z ASCAT PASS
SHOWS 10-15 KNOT NORTHERLY WINDS CONVERGING WITH 10-15 KNOT
WESTERLIES. A 310033Z AMSU MICROWAVE IMAGE DEPICTS WEAK CONVECTIVE
CURVATURE ALONG THE WESTERN PERIPHERY. UPPER LEVEL ANALYSIS SHOWS
THE SYSTEM IS LOCATED UNDER THE RIDGE AXIS IN AN AREA LOW VERTICAL
WIND SHEAR AND GOOD DIVERGENCE ALOFT. SEA SURFACE TEMPERATURES ARE
FAVORABLE FOR DEVELOPMENT. 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 IS POOR.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.7N
139.2E, IS NOW LOCATED NEAR 8.6N 136.5E, APPROXIMATELY 135 NM
NORTHEAST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A BROAD AND WEAK LOW LEVEL CIRCULATION CENTER (LLCC) WITH
THE CONVECTION SHEARED TO THE WEST. A 312334Z SSMIS MICROWAVE IMAGE
DEPICTS WEAK CONVECTIVE CURVATURE. UPPER LEVEL ANALYSIS INDICATES
THE SYSTEM IS LOCATED BENEATH THE SUBTROPICAL RIDGE AXIS IN AN AREA
OF DIVERGENCE ALOFT AND MODERATE VERTICAL WIND SHEAR. SEA SURFACE
TEMPERATURES ARE FAVORABLE FOR DEVELOPMENT. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS LOW.
