ZCZC HFOTCDCP3 ALL TTAA00 PHFO DDHHMM Tropical Storm Akoni Special Discussion Number 7 NWS Central Pacific Hurricane Center Honolulu HI EP122019 100 PM HST Thu Sep 05 2019 An ASCAT-C pass from 1843 UTC revealed tropical storm force winds in the vigorous deep convection blowing up to the east and southeast of the low-level circulation center. Thus, this special advisory upgrades TD 12E to Tropical Storm Akoni. The remainder of the forecast philosophy does not change with this update, however the intensity forecast was nudged upward in the short term to better agree with the analyzed current intensity. Akoni remains a very asymmetric and disorganized system, but is expected to gradually intensify over the next few days.
