AN AREA OF CONVECTION (INVEST 99S) HAS PERSISTED NEAR 15.5S
130.0E, APPROXIMATELY 102 NM EAST OF WYNDHAM, AUSTRALIA. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY AND A 140941Z SSMIS 91 GHZ
MICROWAVE IMAGE DEPICT AN ORGANIZED LOW-LEVEL CIRCULATION (LLC) WITH
DEEP CONVECTIVE BANDING IN THE WESTERN AND NORTHERN QUADRANTS.
ANIMATED RADAR IMAGERY AND SURFACE OBSERVATIONS SUPPORT THE CURRENT
POSITION NEAR THE COAST AND CONFIRM A QUASI-STATIONARY MOTION OVER THE
PAST 12 HOURS. SURFACE OBSERVATIONS FROM POINT FAWCETT, TO THE NORTH,
INDICATE 20 TO 25 KNOT WESTERLIES WITH GUSTS AS HIGH AS 40 KNOTS,
HOWEVER, CORE WINDS ARE GENERALLY LESS THAN 15 KNOTS. WHILE THE SYSTEM
IS CURRENTLY OVER LAND, IT IS VERY CLOSE TO THE COAST AND WILL BE
MONITORED FOR A POSSIBLE TRANSITION OVER WATER. UPPER-LEVEL CONDITIONS
ARE FAVORABLE WITH ROBUST OUTFLOW ALOFT AND LOW (10-15 KTS) VERTICAL
WIND SHEAR. FRICTIONAL EFFECTS OVER LAND ARE HINDERING DEVELOPMENT BUT
SURFACE PRESSURE VALUES ARE CLIMATOLOGICALLY LOW AT 997 MB. GLOBAL
MODELS ARE IN AGREEMENT THAT 99S WILL REMAIN NEAR THE COAST OF
AUSTRALIA OVER THE NEXT 24-48 HOURS WITH LITTLE INTENSIFICATION.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 997 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN
THE NEXT 24 HOURS IS LOW.

Tropical low moving over the Pilbara
A tropical low is located over inland parts of the east Pilbara and moving westwards.
It is expected to weaken over land late in the week.
Rain areas with squally weather conditions are expected through the Pilbara over the next few days
