As expected, Andrea is likely to be a short-lived event. The
cyclone's cloud pattern has continued to degrade, and Andrea is now
essentially devoid of deep convection. In fact, at first glance,
the upper-level low to the southwest of the center appears to be
the most dominant feature. Based on the lack of convection and a
buoy observation not far to the north of Andrea, the system is
being downgraded to a subtropical depression. Since the cyclone is
expected to remain under the influence of the upper low and in and
environment of dry mid-level air for the next day or so, Andrea is
likely to degenerate into a remnant low pressure area in a day or
less.

The system has moved a little more to the north than previously
estimated and the initial motion is 360/7. Upper-level westerlies
should cause the cyclone to turn eastward in 12-24 hours until
dissipation. The official track forecast is similar to but a
little slower than the dynamical model consensus, TVCN.
