Issued at 500 AM AST Fri Sep 04 2020 000 WTNT45 KNHC 040835 TCDAT5 Tropical Depression Omar Discussion Number 15 NWS National Hurricane Center Miami FL AL152020 500 AM AST Fri Sep 04 2020 Although it is situated over fairly warm waters of a little over 27 deg C, Omar has been producing very little deep convection overnight while it continues to be affected by strong northerly shear. Some dry air is also being entrained into the circulation. The current intensity of 25 kt is based on continuity from earlier scatterometer measurements. If the lack of convection continues, Omar will be declared a remnant low pressure system later today. In any event, the cyclone should become absorbed by a frontal trough within a couple of days. After turning east-southeastward, Omar is now headed east at a rather slow pace, or 090/6 kt. The system should turn toward the northeast and accelerate ahead of a large mid-level trough within 36-48 hours. The official forecast is somewhat faster than the previous one but slower than the latest track model consensus predictions.
