Tropical Storm Kiko Discussion Number 36
NWS National Hurricane Center Miami FL EP132019
200 AM PDT Sat Sep 21 2019
The initial intensity remains 55 kt based on recent Dvorak
satellite intensity estimates. All of the intensity guidance
continues to show quick weakening as the cyclone moves over
marginal SSTs and into a drier and slightly more stable
environment. The new NHC intensity forecast is similar to the
previous advisory, except the intensity has been held steady for
the next 36 hours due to forecast very low shear conditions by the
GFS and ECMWF models.
The initial motion estimate is 360/02 kt. Despite this most
recent slow northward jog, the new NHC guidance still shows Kiko
turning westward later today, followed by an unusual wave-like
motion as mid-level ridge to the north fluctuates in strength during
the 5-day period. The new NHC track is close to the latest consensus
aids and similar to the previous NHC forecast.
