Post-Tropical Cyclone Kenneth Forecast Discussion Number 22
2017-08-23 22:33:36| National Hurricane Center (East Pacific)
Issued at 200 PM PDT Wed Aug 23 2017 000 WTPZ43 KNHC 232033 TCDEP3 Post-Tropical Cyclone Kenneth Discussion Number 22 NWS National Hurricane Center Miami FL EP132017 200 PM PDT Wed Aug 23 2017 Kenneth's organized deep convection has been gone for over 12 hours now. Satellite images also suggest it is losing its tropical character, with some possible frontal structures developing near and northeast of the center. Thus, it no longer meets the requirements of a tropical cyclone, and this is the final advisory. The wind speed is held at 35 kt owing to the tight low-level circulation seen on visible imagery. The post-tropical cyclone should gradually spin down over cold waters and generally move north-northwestward with some decrease in forward speed over the next couple of days. Later in the forecast period, when the cyclone is likely to be very weak and shallow, a turn toward the northwest is expected following the low-level flow. The official track forecast is very close to the previous one.
