Moderate convection persists near the centre with increasing curvature over the last four to six hours. FT based on poorly defined DT of 2.5 [curved band of 0.4 on IR], MET and PAT give 2.5. Winds are likely strongest on the southern side in the E/SE flow assisted by synoptic forcing and storm motion. The broadscale environment is generally conducive for development, the vertical shear being low and reasonable upper level outflow. Slow development has been observed over the past 6 hours and there is the potential for further development overnight with the diurnal convective cycle so it may intensify into a tropical cyclone from late this morning. Gales remain most likely in the southern sector. The low should continue moving to the west-northwest and accelerate somewhat under the influence of a developing mid-level ridge across Queensland and the central Coral Sea. Copyright Commonwealth of Australia == The next bulletin for this system will be issued by: 30/0100 UTC by Brisbane TCWC.
