Eastern Pacific Tropical Weather Outlook

ABPZ20 KNHC 041149

500 AM PDT SUN OCT 4 2015

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

A broad and elongated area of low pressure located about 1000 miles
southwest of the southern tip of the Baja California peninsula
continues to produce disorganized showers and thunderstorms.  While
some gradual development is possible, environmental conditions
are expected to become less favorable during the next few days while
this system moves slowly northeastward or northward.
* Formation chance through 48 hours...low...30 percent
* Formation chance through 5 days...medium...40 percent

The remnants of Marty, located about 100 miles southwest of
Mazatlan, Mexico, are producing a large area of showers and
thunderstorms.  Strong upper-level winds are expected to prevent
significant development of this system before it moves inland over
western Mexico later today or tonight. Regardless of development,
heavy rainfall is likely over portions of western Mexico during
the next day or so.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...10 percent
