1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 9.9N 104.7W TO 12.0N 107.9W
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 18 TO 23 KNOTS. METSAT

061719Z ASCAT-C IMAGE SHOWS A BROAD CIRCULATION WITH 18-23KT WINDS OVER
THE WESTERN QUADRANT. ENVIRONMENTAL ANALYSIS INDICATES THAT INVEST 91E
IS IN A FAVORABLE AREA FOR DEVELOPMENT DUE TO GOOD OUTFLOW ALOFT, LOW
(LESS THAN 15 KNOTS) VERTICAL WIND SHEAR, AND VERY WARM (30C) SEA
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT THAT INVEST 91E
WILL CONTINUE TO GRADUALLY DEVELOP AND TAKE A NORTHWEST TRACK OVER THE
NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE
