West of Spain: Post-frontal Low Undergoing More Tropical Transition
|
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.
