surface wind data from around 13/2200 UTC indicated that the
circulation had become better defined, and that surface winds of
25-28 kt existed in the southwestern quadrant. Since then, deep
convection has increased, and it is presumed that the surface winds
and circulation definition have increased in response, which
justifies the initiation of advisories on TD-21.
The depression is expected to be short-lived as a tropical cyclone.
Having said that, there is a narrow window of opportunity today and
tonight for the cyclone to strengthen into a tropical storm before
strong westerly shear in excess of 30 kt is forecast to induce rapid
weakening on Tuesday. The cyclone is expected to degenerate into a
remnant low by Tuesday night, and then dissipate over water on
Friday, if not sooner.
