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.
