An interesting 1002 mb low pressure system with some
characteristics of a tropical storm has developed off the coast
of Africa, a few hundred miles west-southwest of the Canary
Islands. ... The storm formed over the weekend from an isolated
cold-cored low that was wandering over the Atlantic, and phase
space analyses from Florida State University revealed that the
low developed a partial warm core over the weekend. A
respectable amount of heavy thunderstorm activity has built near
the storm's center, characteristic of a tropical storm. The low
is over cool 21 - 22°C water, far colder than the typical 26°C
needed for a tropical storm to form. These SSTs are about 1 -
2°C warmer than usual for this time of year.
