TROPICAL STORM AGATHA DISCUSSION NUMBER   9
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP022016
800 PM PDT SUN JUL 03 2016

Although Agatha still has a tight circulation, the overall
convective pattern has lost some organization during the last
several hours.  The initial intensity has been lowered a little to
35 kt, in agreement with the Dvorak classification from TAFB and ADT
estimates from CIMSS at the University of Wisconsin.  Agatha is
currently over cool 25 deg C waters and is embedded in a stable air
mass, as evident by the field of stratocumulus clouds over the
western half of the circulation. These unfavorable conditions,
combined with a notable increase in southwesterly shear during the
next day or so, should cause Agatha to weaken to a remnant low in
about 36 hours, or perhaps sooner. The remnant low is forecast to
dissipate in about 4 days.

The tropical storm is moving west-northwestward at about 10 kt while
being steered by a mid-level ridge over northwestern Mexico.  The
weakening system is expected to gradually turn westward during the
next couple of days as it becomes a shallower cyclone and is mainly
steered by the low-level trade wind flow.  The NHC track forecast is
nudged a little to the south of the previous one and lies very close
to the multi-model consensus TVCE.
