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

Recent satellite data indicate that the wind field of a broad area
of low pressure located several hundred miles southwest of the
southern tip of the Baja California peninsula remains elongated, and
the system does not have a well-defined center.  In addition, the
associated shower and thunderstorm activity has not increased in
organization.  Although the window of opportunity for development is
decreasing, a tropical depression is still likely to form by tonight
or on Sunday while the system moves northward at 5 to 10 mph.  By
Sunday night or Monday, however, additional development is not
expected due to cooler waters and stronger upper-level winds.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.

A broad area of low pressure is forming a couple of hundred miles
west of the the coasts of Nicaragua and Costa Rica.  Gradual
development of this system is possible over the next several days,
and a tropical depression could form by midweek while it moves
west-northwestward at about 10 mph near or just off the coast of
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...60 percent.
