Hurricane and Tropical Cyclones


Tropical Weather Discussion

For the eastern North Pacific...east of 140 degrees west longitude:

Special tropical weather outlook issued to update the discussion of
the low pressure system southwest of Mexico.

Updated:  satellite-derived wind data indicate that the low
pressure system located about 300 miles southwest of Manzanillo,
Mexico, is producing a small area of gale-force winds.  Although the
associated shower and thunderstorm activity has not yet acquired
sufficient organization or persistence for the low to be considered
a tropical cyclone, only a slight increase in organization would
lead to the development of a tropical storm, and advisories could be
initiated later today.  This system is expected to move slowly
northward and then northwestward near the southwestern coast of
Mexico and the extreme southern Baja California peninsula during the
next few days, and interests in these areas should monitor the
progress of the disturbance.  Locally heavy rains could cause
life-threatening flash floods and mud slides over portions of
southwestern Mexico during the next few days.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.


For additional information on the low please see high seas forecasts
issued by the National Weather Service...under AWIPS header
