L () PUBLIC ADVISORY # FORCE THIRTEEN , ...... SUMMARY OF INFORMATION ----------------------------------- LOCATION...NEAR ... MAXIMUM SUSTAINED WINDS...MPH...KM/H MINIMUM CENTRAL PRESSURE...MB WATCHES AND WARNINGS ----------------------------------- There are no coastal watches or warnings in effect.
DISCUSSION ----------------------------------- 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.
