Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Thu Sep 13 2018

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

Shower activity associated with a broad area of low pressure
located a couple of hundred miles west-southwest of Cabo Corrientes,
Mexico, is diminishing.  Upper-level winds are not particularly
conducive, so any development of this system should be slow to occur
over the next few days while the disturbance drifts
west-southwestward.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

An area of low pressure is expected to develop well south of the
southwestern coast of Mexico over the weekend.  Thereafter,
environmental conditions appear conducive for gradual development,
and a tropical depression could form while the system moves
generally westward to west-northwestward at 10 to 15 mph south of
Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
