2. A tropical wave located about 900 miles south-southwest of the
southern tip of the Baja California peninsula is producing
disorganized shower and thunderstorm activity.  Environmental
conditions continue to support slow development, and a tropical
depression could form later this week while the system moves
westward to west-northwestward at about 10 mph.

2. A low pressure system located more 900 miles southwest of the
southern tip of the Baja California peninsula is producing a large
area of cloudiness and thunderstorms.  Environmental conditions are
expected to gradually improve, and a tropical depression could form
during the next few days while the system moves westward to
west-northwestward at about 10 mph.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...60 percent.

2. A well-defined low pressure system located more 900 miles southwest
of the southern tip of the Baja California peninsula continues to
produce a large area of cloudiness and thunderstorms.  Environmental
conditions are expected to gradually become more conducive for
development, and a tropical depression is likely to form during the
next few days while the system moves westward to west-northwestward
at about 10 mph.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.

2. A low pressure system located a little over 900 miles southwest of
the southern tip of the Baja California peninsula continues to
produce a large area of cloudiness and thunderstorms.  Environmental
conditions are expected to become more conducive for development by
mid-week, and a tropical depression is likely to form during the
next few days while the system moves westward to west-northwestward
at about 10 mph.
* Formation chance through 48 hours...medium...60 percent.

SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 97E)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
275 NM EITHER SIDE OF A LINE FROM 13.1N 119.4W TO 16.5N 136.7W
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 20 TO 25 KNOTS. METSAT
IMAGERY AT 191918Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 14.0N 120.6W. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 10
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 97E) IS LOCATED AT 14.0N
120.6W, APPROXIMATELY 624 NM WEST SOUTHWEST OF SOCORRO. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS
IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
202330Z.

2. Another low pressure system located more than 900 miles
west-southwest of the southern tip of the Baja California peninsula
is producing disorganized showers and a few thunderstorms.
Conditions have become less conducive for development, however a
tropical depression could still form within the next couple of days
while the system moves westward to west-northwestward at about 10
mph.
* Formation chance through 48 hours...medium...40 percent.

AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT (WTPN22 PHNC 192330)//
RMKS/
1. REMARKS: THIS CANCELS REF A (WTPN22 PHNC 192330). THE AREA OF
CONVECTION (INVEST 97E) IS LOCATED AT 14.0N 120.6W, APPROXIMATELY 630 NM
WEST SOUTHWEST OF SOCORRO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A FULLY EXPOSED AND RAGGED LLCC WITH LITTLE CONVECTION. DESPITE
LOW VERTICAL WINDSHEAR, 97E CROSSED INTO AN AREA OF RELATIVELY COOL SEA
SURFACE TEMPERATURES (26-28 CELCIUS) AND DECREASED UPPER LEVEL SUPPORT,
WITH POOR OUTFLOW ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 20-25 KNOTS AND SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.
IN VIEW OF THE UNFAVORABLE FORECAST FOR THIS SYSTEM, 97W IS NO LONGER
CONSIDERED SUSPECT FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS.

2. Another low pressure system located more than 900 miles west-
southwest of the southern tip of the Baja California peninsula is
producing limited shower and thunderstorms activity. Conditions have
become less conducive for development and the chance of this system
becoming a tropical cyclone is decreasing.  The system is forecast
to move little during the next couple of days.
