1. REMARKS: THIS CANCELS REF A (WTPS21 PGTW 191230). THE SYSTEM IS
CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED
AS HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED
ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS INVEST 94P WITH A
HIGHLY ELONGATED CIRCULATION AND CONVECTION DISPLACED FAR TO THE SOUTH
AND NORTH OF THE CENTER. THE CENTER HAS BECOME IRREGULAR AND ILL-DEFINED
OVER THE PAST 6 HOURS AS THE SYSTEM QUICKLY ACCELERATES POLEWARD.
ENVIRONMENTAL ANALYSIS INDICATES THAT 94P IS IN AN UNFAVORABLE
ENVIRONMENT FOR DEVELOPMENT CHARACTERIZED BY STRONG POLEWARD OUTFLOW
AND LOW TO MODERATE (15-20 KTS) VERTICAL WIND SHEAR, GREATLY OFFSET BY
SIGNIFICANT DRY AIR ENTRAINMENT FROM THE WEST AND MARGINAL (25-26 C)
SEA SURFACE TEMPERATURES. GLOBAL MODELS AGREE ON 94P CONTINUING TO
TRACK QUICKLY SOUTHEASTWARD OVER THE NEXT 24 HOURS WITH AN ASYMMETRIC
WIND FIELD. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER
SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED
FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30
TO 35 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 989 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO LOW.//
NNNN
THE AREA OF CONVECTION (INVEST 94P) PREVIOUSLY LOCATED NEAR
19.5S 162.5E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
