Surface observation and satellite analysis suggest that 94W is now a Tropical Depression (26W by PGTW)… Convection has increased but easterly shear is still pushing the convection to the west…
There is a poleward outflow channel… and vertical shear is decreasing… Slight development may be possible in the coming 24 hours but TD 26W is not expected to become a Tropical Storm…
At 2000 HKT / 1200 UTC, Truong Sa (Vietnam) reported northerly winds of 58 km/h ( 31 kt)… with a sea level pressure of 1005.3 hPa… a 2.4 hPa drop in the past 24 hours…
