000 ABPZ20 KNHC 232327 TWOEP TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 500 PM PDT SAT MAY 23 2015 For the eastern North Pacific...east of 140 degrees west longitude: Satellite data and surface observations indicate that the circulation of the low pressure system located about 1600 miles southeast of the Big Island of Hawaii is currently not well defined. Some development of this system is possible during the next day or two, and it has the potential to become a tropical depression while it moves slowly northward. Thereafter, development is not expected due to the proximity of the disturbance to its northeast and north. * Formation chance through 48 hours...high...70 percent * Formation chance through 5 days...high...70 percent Shower activity remains limited in association with a broad area of low pressure located about 1500 miles west-southwest of the southern tip of Baja California. Gradual development of this system is possible during the next couple of days while it moves west-northwestward at 10 to 15 mph. After that time, the low is expected to move over cooler water and into an area of less favorable upper-level winds which should inhibit development. * Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...medium...60 percent An area of low pressure could form early next week several hundred miles south of the coast of Mexico. Environmental conditions are expected to be conducive for subsequent slow development of the system while it moves west-northwestward. * Formation chance through 48 hours...low...near 0 percent * Formation chance through 5 days...low...20 percent $$ Forecaster Cangialosi
