Issued at 900 AM MDT Sun Aug 30 2020 000 WTPZ44 KNHC 301436 TCDEP4 Tropical Depression Iselle Discussion Number 17 NWS National Hurricane Center Miami FL EP142020 900 AM MDT Sun Aug 30 2020 Iselle is skirting the line between tropical cyclone and remnant low, producing a small amount of deep convection during the past few hours. While this isn't particularly organized thunderstorm activity, for now it is enough to keep advisories going another 6 hours. The initial intensity is set to 30 kt, near the latest TAFB T-number. Iselle is still expected to degenerate into a remnant low later today due to persistent easterly shear and a dry and stable environment. Model guidance all show the system becoming a trough by Tuesday, so the dissipation phase has been pushed ahead from the last forecast. The guidance also remains in good agreement on a northward track today, followed by a north-northwest turn overnight. The track is shifted a bit to the east because of a more eastward initial position, otherwise it is unchanged.
