Tropical Depression Omar Discussion Number  16
NWS National Hurricane Center Miami FL       AL152020
1100 AM AST Fri Sep 04 2020

Omar produced minimal deep convection from around 2100 UTC
yesterday through 1200 UTC this morning. Since that time, a new
burst of convection has developed close enough to the depression's
center to justify continuing advisories for the moment. If this
convection dissipates soon, like a few small overnight bursts did,
Omar will likely be declared post-tropical this afternoon due to a
lack of organized convection. ASCAT-B showed a few believable 
25-30 kt vectors and is the basis for the intensity analysis.

Omar's status has no meaningful bearing on the forecast. An
approaching deep-layer trough from the west should cause the weak
cyclone to turn northeastward or north-northeastward later today
and accelerate in that direction through the weekend. A lack of
deep convection and the increase in forward speed will likely cause
Omar to dissipate by early Sunday.
