Gulf of California:
An area of low pressure over the central Gulf of California is
bringing heavy rains to portions of the Mexican state of Sonora.
Although the development chances appear to be decreasing since the
system is expected to move inland later this morning, heavy rains
will likely continue across portions of the state of Sonora
during the next day or so, and could cause isolated flooding.

Southwest of Southwestern Mexico:
An area of low pressure could form well offshore of southwestern
Mexico within the next few days. Environmental conditions appear
conducive for some gradual development, and this system could become
a tropical depression early next week while it moves slowly
northwestward or northward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...50 percent.

A tropical wave is producing disorganized showers and thunderstorms
well to the south of the southern tip of the Baja California
Peninsula. Upper-level winds are forecast to be unfavorable for
significant development through the weekend as the system moves
westward at 10 to 15 mph. However, some gradual development of this
system is possible early next week when it reaches the western
portion of the east Pacific basin.
* Formation chance through 48 hours...low...near 0 percent.
