Tropical Depression JULIA Forecast Discussion Number 17
2016-09-18 04:32:48| National Hurricane Center (Atlantic)
Issued at 1100 PM EDT SAT SEP 17 2016 000 WTNT41 KNHC 180232 TCDAT1 TROPICAL DEPRESSION JULIA DISCUSSION NUMBER 17 NWS NATIONAL HURRICANE CENTER MIAMI FL AL112016 1100 PM EDT SAT SEP 17 2016 I have two options this evening. The first one, which is very attractive, is to classify Julia as a remnant low and terminate advisories. The second one is to keep Julia as a tropical depression in this advisory given that there was deep convection associated with the center only a few hours ago. Although it lacks thunderstorm activity, the convection has returned over and over again for the past day or so when we think it will not. I will then adopt the second option. Strong upper-level northerly winds are expected to continue affecting the circulation, and if the convection returns it will quickly be removed from the center. Therefore, Julia is forecast once again to become a remnant low soon and gradually decay. Julia is drifting northwestward at about 3 kt embedded within very light steering flow. Most of the global models keep a low meandering over water off the southeast U.S. coast, and so does the NHC forecast. Some global models actually regenerate the low, but given the strong shear, this solution does not seem realistic.
