ZCZC MIATCDEP4 ALL TTAA00 KNHC DDHHMM Remnants Of Priscilla Discussion Number 4 NWS National Hurricane Center Miami FL EP192019 1000 PM CDT Sun Oct 20 2019 The rugged terrain of Mexico has taken a toll on Priscilla. Surface observations indicate that the system no longer has a closed surface circulation, and therefore this is the last advisory issued by the National Hurricane Center on this system. Even though the surface circulation has dissipated, there is still a fair amount of deep convection associated with the remnant trough over portions of southwestern and west-central Mexico. Since the surface trough is expected to linger for another couple of days over southwestern Mexico, there remains a significant threat of heavy rains and flash flooding over that region.
