Cylonic storm Akash and Wpac invest 90W

Meanwhile in the NW Pacific Invest 90W is being listed as a low pressure area (LPA) by JMA and has been upgraded to FAIR by JTWC.

A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.5N 149.5E, IS NOW LOCATED NEAR 6.8N 148.5E, APPROXIMATELY 205 NM WEST OF CHUUK. RECENT ANIMATED MULTISPECTRAL SATELLITE IMAGERY INDICATES THE LOW LEVEL CIRCULATION CENTER (LLCC) IS STILL CONSOLIDATING, WITH INCREASING LOW LEVEL INFLOW FROM THE WESTERN QUADRANTS. A 132142ZAMSU MICROWAVE IMAGE REVEALS CONVECTIVE BANDING DEVELOPING IN THE NORTHWESTERN QUADRANT OF THE STORM, ALTHOUGH CONVECTION HAS YET TO DEVELOP NEAR THE LLCC. AN 131951Z WINDSAT SHOWS A WELL-DEFINED BAND OF WESTERLIES ALSO BEGINNING TO WRAP TOWARD THE LLCC. IN THE UPPERLEVELS, AN ANTICYCLONE IS BUILDING TO THE EAST OF THE DISTURBANCE, LOWERING VERTICAL WIND SHEAR AND IMPROVING RADIAL OUTFLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED TO BE 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. DUE TO THE IMPROVING CENTRAL ORGANIZATION AND UPPER LEVEL ENVIRONMENT, THEPOTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS FAIR.
