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.
