AN AREA OF CONVECTION HAS PERSISTED NEAR 12.2S 115.5E,
APPROXIMATELY 510 NM NORTH-NORTHWEST OF PORT HEDLAND, AUSTRALIA.
A 251755Z AMSR-E PASS REVEALS A DEVELOPING LOW LEVEL CIRCULATION
CENTER (LLCC) WITH CURVED BANDS OF CONVECTION FORMING ON THE
CIRCULATION PERIPHERY. SYNOPTIC OBSERVATIONS NEAR THE DISTURBANCE
VERIFY THE LOW-LEVEL CYCLONIC TURNING AND REFLECT SURFACE PRESSURES
NEAR 1001 MB. UPPER LEVEL ANALYSIS REVEALS THE FORMING LLCC IS
SUPERPOSED BY AN UPPER LEVEL ANTICYCLONE, WITH LOW VERTICAL WIND
SHEAR AND EXCELLENT OUTFLOW POTENTIAL. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE NEAR 1000 MB. DUE TO AN IMPROVING LLCC AND A VERY
FAVORABLE UPPER LEVEL ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS FAIR.

Already the Karratha-Exmouth area is under a watch again, and this looks like it might become the second severe TC of this season to hit them at this rate.
