Post-Tropical Cyclone IAN Forecast Discussion Number 17
2016-09-16 16:54:45| National Hurricane Center (Atlantic)
Issued at 1100 AM AST FRI SEP 16 2016 000 WTNT45 KNHC 161454 TCDAT5 POST-TROPICAL CYCLONE IAN DISCUSSION NUMBER 17 NWS NATIONAL HURRICANE CENTER MIAMI FL AL102016 1100 AM AST FRI SEP 16 2016 Ian has transitioned into an extratropical low this morning. Any of the remaining weak-to-moderate convection is the northern side of the circulation, with cold air wrapping into the center of the cyclone as it is overtaken by a cold front. The initial intensity of 55 kt is based on ASCAT data. Ian should move quickly northeastward and gradually weaken before a larger extratropical low absorbs it in about 2 days. The track, intensity, and wind radii forecasts are based largely on guidance from the Ocean Prediction Center.
