TROPICAL DEPRESSION PAINE DISCUSSION NUMBER 12
NWS NATIONAL HURRICANE CENTER MIAMI FL EP172016
200 PM PDT TUE SEP 20 2016
Paine consists of a well-defined circulation of low-level clouds,
as all of the deep convection dissipated around 10-11Z. The initial
intensity has been set to 30 kt based on a blend of the latest
Dvorak Final-T and CI numbers from TAFB and SAB. Since it is
unlikely that deep convection will return given the continued strong
shear and a track over very cool waters, Paine will likely be
declared a post-tropical remnant low tonight. The remnant low will
slowly spin down during the next day or so and should dissipate over
the Baja California peninsula in 36 to 48 hours.
The initial motion estimate is 005/13. Paine's track should
gradually bend northeastward during the next 24 to 36 hours as it is
steered by a mid-level ridge centered over the southern United
States, and the shallow cyclone will lose some forward speed during
that time. The new NHC track forecast is an update of the previous
one and is again close to a blend of the GFS and ECMWF models.
Deep-layer moisture associated with Paine or its remnants is
expected to spread over portions of the northern Baja California
peninsula of Mexico and the southwestern United States during the
next day or so. This could enhance the rainfall potential in these
areas.
