The Portuguese Institute for the Sea and the Atmosphere has discontinued all warnings for the Azores.

Lorenzo has completed its transition into a powerful extratropical cyclone and this will be the last NHC advisory on this system. The center has become exposed on the southwestern edge of the cloud shield, and recent ASCAT data indicate that the system has acquired frontal features. The initial intensity is set at 70 kt, which is a little above the scatterometer data since there is typically a low bias in that instrument at these wind speeds. The global models suggest that the post-tropical cyclone will only gradually weaken during the next 24 to 36 hours as it approaches Ireland. A faster rate of weakening is expected Thursday night and Friday when the cyclone moves southeastward over Ireland and the United Kingdom. The low should dissipate over southeastern England by late Friday.

The cyclone continues to move rapidly northeastward or 040/37 kt and this general motion should continue into Thursday. After that time, the cyclone is expected to turn eastward and then southeastward within an area of weaker westerly flow. The global model guidance is in good agreement, and the NHC track forecast is closest to the ECMWF model.
