000 WTPZ41 KNHC 222028 TCDEP1 POST-TROPICAL CYCLONE RICK DISCUSSION NUMBER 18 NWS NATIONAL HURRICANE CENTER MIAMI FL EP212015 100 PM PST SUN NOV 22 2015 Rick has become a swirl of low clouds that has been devoid of organized deep convection for more than 12 hours. As a result, Rick is now a post-tropical remnant low, and this will be the last NHC advisory on this system. The initial intensity remains 30 kt, which is in agreement with the latest Dvorak current intensity estimate from TAFB. Dry air, strong southwesterly shear, and cooler sea surface temperatures along the forecast track of the low should cause weakening during the next couple of days, and dissipation is expected within 72 hours. The initial motion estimate is 310/7 kt. The low should turn northward during the next day or so, then become nearly stationary as the low-level steering flow weakens. After that time, the remnant low is forecast to turn eastward or southeastward before dissipation occurs. The new NHC track forecast is in good agreement with the latest global model guidance and is similar to the previous NHC advisory.
