System expected to become tropical depression


A disorganized area of low pressure located about 975 miles southeast of the Big Island of Hawaii continues to produce widely scattered thunderstorms across a broad area. This system may develop during the next few days as it moves westward across the central Pacific, National Weather Service forecasters said.

Shower activity associated with a low pressure area located about 1700 miles west-southwest of the southern tip of the Baja California peninsula has changed little in organization today. However, satellite data indicate winds of near tropical storm force north of the center, and environmental conditions appear conducive for development. This system is expected to become a tropical depression during the next day or two while it moves westward or west-northwestward at about 10 mph. Upper-level winds are forecast to limit the development chances by the weekend.

A large area of disorganized showers and thunderstorms continues well south of the coast of southeastern Mexico. Upper-level winds are expected to become more favorable for development of this system over the next few days while it moves west-northwestward at 10 to 15 mph.

An area of low pressure has formed about 1100 miles southwest of the southern tip of the Baja California peninsula. Some additional development of this system is possible by the weekend while it moves to the west or west-northwest at 10 to 15 mph.

Another area of low pressure could form well south of southeastern Mexico by early next week. Some gradual development of this system is possible after that time.
