Tropical Storm KIKO


Tropical Storm Kiko Discussion Number  40
NWS National Hurricane Center Miami FL       EP132019
1100 PM HST Sat Sep 21 2019

A small but growing burst of deep convection has resumed near the
center of Kiko, but the cyclone is considerably weaker than earlier
today. ASCAT data indicated maximum winds of 30-35 kt, and
35 kt will be the initial intensity.  Within about 24 hours, Kiko
has a chance to re-strengthen as it moves over warmer waters in a
lighter shear region.  Model agreement is in fairly good agreement
on tenacious Kiko intensifying once again.  However, Kiko should
resume weakening again in about 3 days due to a significant
increase in shear and cooler waters, and hopefully the next 48 hours
are the last hurrah of Kiko.

Kiko is moving southwestward tonight at about 7 kt.  The storm
should continue to lose latitude for about the next 24 hours due to
the orientation of a ridge to the northwest. After that time,
the western portion of an incoming mid-latitude trough is forecast
to cut off east of the Hawaiian Islands, causing Kiko to turn
sharply northwestward on days 2-4. Once a remnant low, Kiko is then
expected to be steered by lower-level flow, causing it to turn back
to the southwest.  No significant changes were made to the sinuous
forecast track and, if Kiko survives as long as predicted below, it
would end up one of the 10 longest-lasting tropical cyclones in
eastern Pacific history.
