INVEST 94W AND INVEST 95W WERE UP-GRADED TO MEDIUM AT 05/14UTC.
INVEST 94W AND INVEST 95W WERE UP-GRADED TO MEDIUM AT 05/14UTC.

INVEST 94W. THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED  NEAR 12.1N 140.0E IS NOW LOCATED NEAR 12.6N 139.5E, APPROXIMATELY  565 KM WEST OF GUAM. ANIMATED ENHANCED INFRARED (EIR) SATELLITE  IMAGERY DEPICTS PERSISTENT CONVECTION OBSUCRING A LOW LEVEL  CIRCULATION CENTER (LLCC) WITH LOW LEVEL CLOUDS BEGINNING TO  CONSOLIDATE. INVEST 95W IS IN A MOSTLY FAVORABLE ENVIRONMENT  CHARACTERIZED BY WARM SEA SURFACE TEMPERATURES (SST),  AND LOW VERTICAL WIND SHEAR, OFFSET BY WEAK OUTFLOW ALOFT. GLOBAL  MODELS GENERALLY AGREE THAT INVEST 94W WILL UNDERGO MINIMAL, IF ANY,  CONSOLIDATION AND INTENSIFICATION DURING THE NEXT 24-36 HOURS AS IT  INTERACTS WITH INVEST 95W. THERE IS GENERAL AGREEMENT THAT 94W WILL  INTENSIFY BEYOND 48H TO WARNING STRENGTH. MAXIMUM SUSTAINED  SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL  PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR THE  DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24  HOURS IS UPGRADED TO MEDIUM.

THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED  NEAR 11.2N 131.1E IS NOW LOCATED NEAR 11.0N 129.7E, APPROXIMATELY  680 KM EAST-SOUTHEAST OF LEGAZPI, PHILIPPINES. ANIMATED EIR  SATELLITE IMAGERY DEPICTS PERSISTENT CONVECTION OBSUCRING A LOW  LEVEL CIRCULATION CENTER (LLCC) WITH LOW LEVEL CLOUD LINES WRAPPING  INTO THE CENTER. A 051148Z ASCAT PARTIAL PASS REVEALS 15-20 KT WINDS  ALONG THE OUTSKIRTS OF THE DEEP CONVECTION, AND MARGINAL WRAPPING OF  THE WINDS ON THE WESTERN PERIPHERY. INVEST 95W IS IN A FAVORABLE  ENVIRONMENT CHARACTERIZED BY EQUATORWARD OUTFLOW ALOFT, WARM (30C)  SST, AND LOW VERTICAL WIND SHEAR. GLOBAL MODELS GENERALLY AGREE THAT INVEST  95W WILL UNDERGO MINIMAL, IF ANY, CONSOLIDATION AND INTENSIFICATION  DURING THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE  ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED  TO BE NEAR 1010 MB.
