Upgraded to Fair

AN AREA OF CONVECTION HAS PERSISTED NEAR 5.1N 152.8E,
APPROXIMATELY 160 NM SOUTH-SOUTHEAST OF CHUUK. RECENT ANIMATED
INFRARED SATELLITE IMAGERY SHOWS AN UNORGANIZED AREA OF LIMITED,
MODERATE-TO-DEEP CONVECTION ASSOCIATED WITH A BROAD AREA OF CYCLONIC
TURNING. AN 180607Z QUIKSCAT PASS INDICATES A LARGE 15 TO 20 KNOT
LOW LEVEL CIRCULATION CENTER (LLCC) HAS DEVELOPED WITHIN THIS
BROADER TURNING. STRONG WESTERLY FLOW ALONG THE SOUTH SIDE OF THE
CIRCULATION SUPPORTS FURTHER CONSOLIDATION (AND TIGHTENING) OF THE
LLCC. VERTICAL WIND SHEAR IS LOW AND OUTFLOW HAS BEEN AIDED BY AN
UPPER LEVEL CYCLONE AROUND 40N. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS FAIR.

we have two? wow

[cycloneye]

Only one area to watch,92W.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 5.1N 152.8E
HAS DISSIPATED AND IS NO LONGER CONSIDERED SUSPECT FOR DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
