Tropical Storm Vicente Discussion Number 10
NWS National Hurricane Center Miami FL EP232018
400 PM CDT Sun Oct 21 2018
Vicente's cloud pattern has become less organized today, with the
low-level center becoming exposed near the northeastern edge of a
ragged-looking area of deep convection. Data from a recent
scatterometer overpass indicated that the maximum winds have
decreased to near 35 kt. North-northeasterly vertical wind shear
should prevent strengthening of the system and, in fact, the global
models show the cyclone dissipating in a couple of days. The
official forecast shows, perhaps generously, Vicente weakening to a
depression in 1-2 days and is similar to the latest intensity model
consensus. Obviously, the system could weaken sooner than shown
here.
The storm has been moving just slightly south of due west, or 260/9
kt. Vicente is expected to move around the southwestern and western
periphery of a mid-level ridge extending from the Gulf of Mexico
for the next couple of days. The official forecast is somewhat
faster than the previous one, but is very close to the dynamical
model consensus, TVCN.
