At 300 AM GMT (0300 UTC), the center of Post Tropical Cyclone Julian was located near latitude 38.1 North, longitude 41.9 West. The post tropical cyclone is moving toward the northeast near 26 mph (43 km/h). This general motion is expected to continue through Monday, followed by a turn to the north, then northeast Monday night into Tuesday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Little change in strength is expected through tonight. Tropical storm force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure is 995 mb (29.39 inches).

Julian has been showing signs of a transition into an extratropical cyclone over the past several hours. The deep convection has become detached to the northeast from the low-level center and cloud tops of that convection are warming. A line of convection to the south of the center resembles a frontal boundary, with recent scatterometer data showing a notable wind shift along that line. Based on the structural changes noted above, as well as a majority of FSU phase-space diagrams from the various global models, Julian is estimated to have transitioned to an extratropical cyclone. Recent ASCAT data showed the cyclone's intensity remains 50 kt. The cyclone is forecast to maintain this intensity through Monday before weakening. It is then forecast to dissipate in a few days over the northern Atlantic. The system should continue to move quickly northeastward through Monday, then turn northward and northwestward Monday night into Tuesday.

This is the last advisory on Julian by the National Hurricane Center. Additional information on this system 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
