A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED
NEAR 25N7 160E7 IS NOW LOCATED NEAR 27N9 162E9. THE
SYSTEM IS MOVING TOWARDS THE NORTH-NORTHEAST IN
ENVIRONMENTAL FLOW. ANIMATED WATER VAPOR IMAGERY SHOWS
THE CONVECTION HAS MOVED INTO AN AREA OF STRONG VERTICAL
WIND SHEAR. MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 15
TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO
BE 1015 MB. THIS AREA IS NO LONGER CONSIDERED SUSPECT.

SYNOPTIC DATA FROM SANTA CRUZ ISLAND (WMO 91541)
INDICATES A LOW-LEVEL CIRCULATION WITH ASSOCIATED
PRESSURE FALLS WITHIN 45NM OF THE SATELLITE DERIVED
SURFACE CIRCULATION. ANIMATED WATER VAPOR IMAGERY SHOWS A
WEAK ANTICYCLONE ALOFT, HOWEVER, CONVECTION REMAINS VERY
DISORGANIZED. MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 20
TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO
