West of Spain: Post-frontal Low Undergoing More Tropical Transition
Sun Sep 21 2008 05:08 PM Attachment (335 downloads)

Currently in the vicinity of 36N 15W

Very interesting feature. An extratropical low has lost most of its last remaining frontal connections. Traveling over 22-24 C sea surface temps and (had been) under very low shear, a slow tropical transition has been underway.

Both quikscat and windsat passes from very early this morning (around 0700 UTC) show at that time a very symmetric surface low was already present, with the strongest winds closest to the center.

Some may recall Hurricane Vince (2005), which made landfall in a similar location as the very first officiated tropical cyclone on record to do so there.

Uploaded this early morning's windsat pass and a more recent (1800 UTC) Visible satellite image.
