Post-Tropical Cyclone Omar Forecast Discussion Number 21
2020-09-05 22:31:20| National Hurricane Center (Atlantic)
Issued at 500 PM AST Sat Sep 05 2020 808 WTNT45 KNHC 052031 TCDAT5 Post-Tropical Cyclone Omar Discussion Number 21 NWS National Hurricane Center Miami FL AL152020 500 PM AST Sat Sep 05 2020 Omar continues to separate from a small lingering area of deep convection that is located more than 100 n mi south-southwest of the center. During the past couple of days, Omar has produced just enough convection to maintain its status of a tropical depression, but now it no longer meets the criteria of sufficently organized deep convection to be considered a tropical cyclone. Therefore, this is the last advisory on Omar issued by NHC. The initial intensity of the remnant low is 30 kt based on earlier ASCAT data that showed a region of 25-30 kt winds east of the center. The remnant low is moving northward at 9 kt, a couple of hundred miles east of a cold front. The models suggest that the remnants of Omar should accelerate north-northeastward and merge with the front in about 24 hours, leading to extratropical transition. Dissipation is expected shortly thereafter.
