Issued: Sep 22, 2010 20:00 pm HST

For the central north Pacific, between 140°W and 180.

1. The center or trough of low pressure located about 490 miles south of Molokai continued to move west at around 10 miles an hour over the past 6 hours. Thunderstorms along the east flank of the low moved more slowly, thus becoming increasingly separated from the center. The coverage and intensity of these thunderstorms has diminished over the past 6 hours as well. Slow development of this feature is possible as it continues moving toward the west at about 10 mph during the next couple of days. There is a low chance, 20 percent, of this system becoming a tropical cyclone during the next 48 hours.

Otherwise, no tropical cyclones are expected through Friday evening.
