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. JUSTIFICATION FOR CORRECTION: CORRECTED SYSTEM IN SUBJECT LINE TO
INVEST 97E.

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.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...40 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.
* Formation chance through 5 days...high...80 percent.

展望提升至50%。

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.
