First, the following data issued yesterday by the BoM indicates that the 30-day moving average moved up to -9.8:
20150224,20150325,-9.8
Second as the effect of Tropical Cyclone Nathan has dissipated (see TC 18P in the first image), the Long Paddock Station daily SOI for March 27 2015 moved down to -14.40. This means that within a day or two the BoM SOI will continue becoming more negative.
Third, the first attached Cyclocane image and forecast shows that our current tropical depressions TD-04W is continuing to contribute to a moderate WWB event:
Extract: "THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.2N 160.9E IS NOW LOCATED NEAR 6.5N 160.1E, APPROXIMATELY 115 NM EAST OF POHNPEI.
…
UPPER-LEVEL ANALYSIS INDICATES THE DISTURBANCE IS LOCATED IN AN AREA OF LOW TO MODERATE (10 TO 20 KNOT) VERTICAL WIND SHEAR OFFSET BY GOOD POLEWARD OUTFLOW. ADDITIONALLY, WARM SEA SURFACE TEMPERATURES ARE CONDUCIVE FOR DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. DUE TO INCREASED CONVECTION AND IMPROVED ORGANIZATION, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH."
Finally, the second, third & fourth images are all from Earth nullschool today for the surface wind, 250 hPa wind and the Total Cloud Water, TCW, respectively. These all indicate that the Walker Cell remains in an El Nino pattern.
