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
in closest to the ECMWF model.

Future hazard information on Lorenzo for Ireland and the United
Kingdom can be found in products issued by Met Eireann and the
United Kingdom Met Office.

Lorenzo's expansive circulation is producing very large seas over
the north Atlantic. Full information can be found in High Seas
