Tropical Depression Newton Discussion Number  13

Visible satellite imagery show Newton is reduced to a low-level
swirl devoid of deep convection.  Satellite Dvorak estimates suggest
the intensity is between 25-30 kt.  Therefore, the initial intensity
has been lowered to 30 kt, and Newton is now a tropical depression.

It remains to be seen if Newton is able to develop new central
convection as it moves over a oceanic thermal ridge with warmer sea
surface temperatures.  Environmental conditions are not expected to
improve along the forecast track, however, and global models suggest
Newton will gradually spin down.  The NHC intensity is slightly
lower than the previous advisory and now shows the depression as a
remnant low in 24 hours.  However, given the current satellite
presentation, this could occur sooner.

The depression is moving just north of west at 8 kt.  The shallow
circulation is expected to move westward in the low-level wind flow
for the next day.  This is followed by a gradual turn to the
west-southwest and southwest until the end of the forecast period.
The current forecast track is largely an update of the previous
advisory prediction with only minor adjustments.
