Tropical Depression Sandra Discussion Number   9

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.
