Post-Tropical Cyclone Ana Forecast Discussion Number 8

2021-05-24 04:42:08| National Hurricane Center (Atlantic)

Issued at 1100 PM AST Sun May 23 2021 660 WTNT41 KNHC 240242 TCDAT1 Post-Tropical Cyclone Ana Discussion Number 8 NWS National Hurricane Center Miami FL AL012021 1100 PM AST Sun May 23 2021 Ana has mainly remained devoid of deep and organized convection today, with only a couple of short-lived bursts noted in satellite imagery earlier this morning. The cyclone has been an exposed cloud swirl through the afternoon and evening hours, and Ana continues moving into a hostile environment characterized by cool sea-surface temperatures, dry mid-level air, and increasing vertical wind shear. Thus, Ana has become a post-tropical cyclone, and this will be the final NHC advisory on the system. Although a recent ASCAT-B pass missed the center of post-tropical Ana, it still shows an area of 30-35 kt winds in the southeast quadrant of the low near the edge of the swath. Therefore, the initial intensity is set at 35 kt, with the slightly stronger winds likely just a product of the accelerating forward speed of the system. The post-tropical cyclone is embedded in deep-layer southwesterly flow and will continue to accelerate northeastward until it opens up into a trough and becomes absorbed by a strong baroclinic zone approaching from the northwest on Monday. Additional information on post-tropical Ana can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php FORECAST POSITIONS AND MAX WINDS INIT 24/0300Z 38.3N 55.2W 35 KT 40 MPH...POST-TROPICAL 12H 24/1200Z 41.0N 50.5W 30 KT 35 MPH...POST-TROP/REMNT LOW 24H 25/0000Z...DISSIPATED $$ Forecaster Reinhart/Brown
