000 WTPZ42 KNHC 281440 TCDEP2 TROPICAL DEPRESSION FRANK DISCUSSION NUMBER 28 NWS NATIONAL HURRICANE CENTER MIAMI FL EP072016 800 AM PDT THU JUL 28 2016 Frank has only been devoid of organized deep convection since about 0400 UTC, so the system is still being maintained as a tropical cyclone for this advisory. However, if this downward convective trend continues, which appears likely since Frank is now moving over sub-23 deg C sea-surface temperatures, then the cyclone will become a remnant low pressure system this afternoon in the next advisory package. Continued spin down should result in dissipation of the low-level circulation by 72 hours. Microwave satellite fixes indicate that Frank is now moving at 290/07 kt. The weakening cyclone is forecast to become more vertically shallow over the next 48 hours, which should result in a turn toward the west and then west-southwest, accompanied by gradual deceleration due to weak easterly tradewind flow. The official forecast is similar to the previous track and lies close to the TVCN consensus model.
