Tropical Storm Newton Discussion Number  12

Small bursts of convection continue to form near the center of
Newton's center.  A recent satellite microwave pass still showed
a small curved band in the northern semicircle of the circulation.
Subjective and objective satellite classifications range between
25-35 kt.  The initial intensity is held at a possibly generous 35
kt.

The combination of low environmental relative humidities and
moderate vertical wind shear are expected to slowly weaken Newton, 
despite the relatively warm sea surface temperatures.  There is 
little change in the latest intensity forecast and Newton is still 
expected to become a remnant low in two days and dissipate within 
three days. 

Newton is moving west-northwestward at 7 kt and gradually turning to 
the west.  As convection slowly dwindles, the shallow vortex is 
expected to turn westward and eventually southwestward in the 
low-level flow in the next day or so.  The track guidance is 
tightly clustered and the official forecast track is very similar to 
the previous prediction.
