ZCZC MIATCDEP4 ALL TTAA00 KNHC DDHHMM Tropical Depression Sandra Discussion Number 9 NWS National Hurricane Center Miami FL EP192021 700 AM PST Tue Nov 09 2021 Bursts of deep convection have been forming well to the northeast of Sandra's exposed surface center since Monday evening, but haven't been persistent, during the past 12 hours, to be considered as organized convection. Accordingly, the system will likely be classified as a remnant low this afternoon. Stiff, persistent southerly shear and a stabilizing surrounding atmosphere should cause further weakening, and the remnant low is forecast to open up into a trough on Wednesday. Sandra has continued to move a little south of due west, or 260/11 kt during the past 6 hours. A strengthening ridge to the north of the cyclone should influence a westward to west-southwestward through Wednesday. The official NHC forecast is in line with the various consensus aids and lies close to the previous advisory.
