000 ABPZ20 KNHC 271729 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 1100 AM PDT Fri Sep 27 2019 For the eastern North Pacific...east of 140 degrees west longitude: A low pressure system appears to be forming a few hundred miles south-southeast of Acapulco, Mexico. Although the associated shower and thunderstorm activity is not well organized, this system is likely to become a tropical depression or tropical storm during the next couple of days while it moves west-northwestward to northwestward at about 10 mph near the southern and southwestern coast of Mexico. Interests along this portion of the coast should monitor the progress of the disturbance since tropical storm watches or warnings could be required at any time during the next couple of days. Regardless of development, heavy rainfall, with the possibility of flash flooding and mudslides, is expected near the southern and southwestern coast of Mexico during the next few days. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...80 percent. A small area of low pressure located a few hundred miles southwest of Manzanillo, Mexico, is producing very little shower activity. The low is expected to be absorbed by the larger weather disturbance near the coast of Mexico during the next day or so, and therefore development is not expected. * Formation chance through 48 hours...low... near 0 percent. * Formation chance through 5 days...low...near 0 percent. An area of low pressure is expected to form over the far southwestern portion of the eastern North Pacific by early next week. Some gradual development is possible thereafter while the system drifts slowly eastward or northeastward. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...30 percent. $$ Forecaster Berg/Hagen
