Corrected probability category for first disturbance

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

An elongated area of low pressure located about 1400 miles southeast of the Big Island of Hawaii continues to become less defined. The associated shower activity also remains limited, and the chance for this system to become a tropical cyclone development is decreasing. The disturbance is moving slowly westward and could cross into the Central Pacific basin later today. * Formation chance through 48 hours...low...30 percent * Formation chance through 5 days...low...30 percent

Another broad and elongated area of low pressure located about 1500 miles west-southwest of the southern tip of Baja California is moving west-northwestward at 10 to 15 mph. Although shower activity remains disorganized, some slow development of this system could occur during the next day or so. After that time, however, the disturbance is expected to move over cooler water and into a region of less favorable upper-level winds, which should inhibit development. * Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...medium...50 percent

An area of low pressure is expected to form several hundred miles south of the coast of Mexico during the next few days. Environmental conditions are expected to be conducive for gradual development of the system after mid-week while it moves west-northwestward to northwestward. * Formation chance through 48 hours...low...near 0 percent * Formation chance through 5 days...low...30 percent
