000 ABPZ20 KNHC 190533 TWOEP TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 1100 PM PDT FRI SEP 18 2015 For the eastern North Pacific...east of 140 degrees west longitude: Showers and thunderstorms associated with an area of low pressure located about 400 miles south-southwest of the southern tip of the Baja California peninsula continue to show signs of organization. Environmental conditions are conducive for development during the next day or so while this system moves generally north-northwestward at around 10 mph. After that time, colder water and strong upper- level winds should prevent tropical cyclone formation if it has not already occurred. Regardless of development, moisture from this system could produce heavy rain, life-threatening flash floods and mudslides across portions of the Baja California peninsula and northwestern mainland Mexico through the weekend. * Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...medium...50 percent $$ Forecaster Blake
