Issued at 300 AM MDT Sun Aug 30 2020 000 WTPZ44 KNHC 300836 TCDEP4 Tropical Depression Iselle Discussion Number 16 NWS National Hurricane Center Miami FL EP142020 300 AM MDT Sun Aug 30 2020 Iselle has produced very little deep convection since around 00Z. Earlier partial ASCAT data indicated that the maximum winds have decreased to 30 kt, which is not surprising given Iselle's lack of organization. Iselle is moving into a drier and more stable environment and over progressively cooler SSTs. While some slight redevelopment of convection is possible during the next few hours, it is unlikely to be very well organized and Iselle is forecast become post-tropical later today. The remnants of Iselle will then continue to gradually spin down for another day or two until it dissipates entirely in a couple of days. The cyclone has moved generally north-northeastward to northward during the pas few hours and is slowing down. The guidance is in good agreement that a northward to north-northwestward motion is likely until Iselle dissipates. No changes of note were made to the NHC track or intensity forecasts.
