For the North Atlantic...Caribbean Sea and the Gulf of America:
Eastern and Central Tropical Atlantic:
An area of low pressure located a few hundred miles south of the
Cabo Verde Islands is producing disorganized showers and
thunderstorms. As this system moves slowly westward, a tropical wave
currently over west Africa is expected to merge with it in a couple
of days. Environmental conditions are forecast to be more conducive
for development by midweek, and a tropical depression could form
during the latter half of this week while the system moves westward
to west-northwestward across the central tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...60 percent.
Central Tropical Atlantic:
A broad area of showers and thunderstorms associated with a tropical
wave is located about midway between the coast of west Africa and
the Lesser Antilles. Some gradual development of this system is
possible through mid-week while it moves quickly westward across the
central tropical Atlantic. Upper-level winds are expected to become
less favorable for development later in the week as the system
approaches the Lesser Antilles.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
Western Subtropical Atlantic:
A trough of low pressure located a few hundred miles northwest of
Bermuda is producing disorganized shower and thunderstorm activity.
Some development of this system is possible during the next couple
of days while it moves quickly eastward, well to the north of
Bermuda, across the western and central subtropical Atlantic. The
system is forecast to reach cooler waters later this week, ending
its chances of formation after Wednesday.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

For the eastern and central North Pacific east of 180 longitude:
Central Pacific (CP93):
A broad area of low pressure located about 1100 miles east-southeast
of the Hawaiian Islands is producing disorganized showers and
thunderstorms and is nearly stationary. Environmental conditions
are forecast to be conducive for further development, and a tropical
depression is likely to form by mid-week as the system begins
moving west-northwestward or northwestward across the Central
Pacific.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...high...90 percent.
Western East Pacific:
A large area of disorganized showers and thunderstorms is located
well to the west-southwest of the southern tip of the Baja
California Peninsula. Environmental conditions appear conducive
for some gradual development, and a tropical depression could form
during the next few days while the system moves slowly
west-northwestward to northwestward across the western portion of
the East Pacific.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...60 percent.
Southwest of Mexico:
Disorganized showers and thunderstorms located several hundred miles
south-southwest of the southern tip of the Baja California Peninsula
are associated with a tropical wave. Environmental conditions
appear to be only marginally conducive for slow development during
the next day or two as the system moves west-northwestward at around
15 mph. By late Tuesday or Wednesday, the system is expected to
reach an area of strong upper-level winds, ending its chances for
development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
