Subtropical Depression One Discussion Number 1
NWS National Hurricane Center Miami FL AL012017
1100 AM AST Wed Apr 19 2017
The non-tropical low over the north central Atlantic which has
been tracked by NHC for the past few days has developed organized
convection mainly in a curved band southeast of the center. The
system is still embedded within an upper-low, the outflow is minimal
and the strongest winds are removed from the center of circulation.
Consequently, the low is being classified as a subtropical
depression with an initial intensity of 30 kt. These winds are based
on recent ASCAT data. It is anticipated that shear and cold waters
will not allow intensification, and the subtropical depression is
expected to become absorbed by a large extratropical cyclone in
about 36 hours or sooner.
The subtropical depression is moving toward the north-northeast at
about 10 kt. A gradual turn to the north and north-northwest
around the approaching extratropical low is forecast for the next
24 hours or so.
