For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

1. Showers and thunderstorms associated with a broad area of low
pressure located about 175 miles north-northeast of the Turks and
Caicos Islands have increased overnight. Although the system is
producing wind gusts to near tropical-storm force, satellite
imagery suggests that it lacks a well-defined center. Upper-level
winds are forecast to remain marginally conducive for some
additional development during the next day or so while the system
moves generally northward. Conditions are expected to become
unfavorable for further development by Wednesday when the
disturbance merges with a frontal system over the western Atlantic.
* Formation chance through 48 hours…medium…40 percent.
* Formation chance through 5 days…medium…40 percent.

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

1. A low pressure system is located about 850 miles west-southwest of
the southern tip of the Baja California peninsula. The associated
showers and thunderstorms have increased and become a little better
organized overnight, and only a small increase in organization
could result in the formation of a tropical depression this
morning. The system is forecast to move west-northwestward to
northwestward into less favorable environmental conditions later
today which should hinder additional development after that time.
* Formation chance through 48 hours…medium…50 percent.
* Formation chance through 5 days…medium…50 percent.

2. Another low pressure area located about 1500 miles east-southeast
of the Hawaiian Islands is producing disorganized showers and
thunderstorms. Strong upper-level winds and proximity to dry air
are expected to inhibit significant development of this system while
it moves westward at 10 to 15 mph during the next couple of days.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…10 percent.
