Issued at 500 PM EDT TUE JUN 07 2016 000 WTNT43 KNHC 072020 TCDAT3 POST-TROPICAL CYCLONE COLIN DISCUSSION NUMBER 10 NWS NATIONAL HURRICANE CENTER MIAMI FL AL032016 500 PM EDT TUE JUN 07 2016 Colin is now being analyzed as a fully extratropical cyclone with frontal features. The gusty winds and rainfall has cleared the coast of North Carolina; therefore this will be the final NHC advisory on this system. The low's intensity remains 50 kt, which is in agreement with an earlier ASCAT pass that showed a large area of 40-45 kt winds well to the southeast of the center. The extratropical cyclone will likely deepen tonight due to baroclinic energetics, but gradual weakening is forecast to begin on Wednesday while the low moves over the North Atlantic. The forecast intensities and wind radii are based on guidance provided by the Ocean Prediction Center. The cyclone is racing northeastward at about 35 kt, and this general motion is expected to continue during the next day or so. After that time, the low should decelerate as it moves moves around a couple of larger extratropical lows over the North Atlantic. This is the last advisory issued by the National Hurricane Center on Colin.
