Sunday Evening Update

Kiko weakening
On this late afternoon - Hawaiian time - Kiko is showing signs of weakening. Convection associated with the eye wall is not as extensive nor the cloud tops as high. Pressure measured from the reconnaissance aircraft also is much higher. This all points to weakening and the official estimate is likely fairly generous for top wind speed. High swell on the northern and eastern facing beaches will be the primary concern.

Wednesday Evening Update

Remnants of Kiko NNW of Islands
It is interesting that Kiko was deemed a post tropical low on the 5 am HST advisory this morning as no convection was associated with the low. Since that time several hours ago, a resurgence of convection has built. IMO, is that Kiko remains at least a depression or possible minimal storm level.
