Low pressure in Central Atlantic (Is Invest 90L)

[Hurricaneman]

Wouldnt be surprised if 90L is declared today

[Hammy]

ASCAT shows the frontal nature to the east is weakening as the sharp wind shift and strong winds to the north are no longer present this morning.

Up to 20%-40%.

SPECIAL TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
150 PM EST SUN JAN 10 2016

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

An extratropical low pressure system located over the central
Atlantic Ocean about 900 miles east of Bermuda is producing a large
area of gale-force winds and maximum winds of hurricane force.
Shower activity is currently limited near the center, but this low
could gradually acquire some subtropical or tropical characteristics
during the next few days while it moves southeastward and then
eastward into the eastern subtropical Atlantic. Regardless of
subtropical or tropical cyclone formation, this system is expected
to produce hazardous marine conditions over portions of the central
and eastern Atlantic for the next few days. For additional
information, see High Seas Forecasts issued by the National Weather
Service. The next Special Tropical Weather Outlook on this system
will be issued by 2 PM EST Monday.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...medium...40 percent

Somewhat surprised it is not an Invest yet.

Looks subtropical to me as it looks like it has seperated from the front and has a CDO around a possible forming eye like feature

The convection around the center is impressive for this time of year and the system does have some resemblance to a subtropical cyclone. But recent OSCAT imagery reveals that even close to the center , there are sharp wind shifts to the north--indicating the system still has frontal characteristics.

40/40

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

A non-tropical low pressure system located over the central Atlantic
Ocean about 900 miles southwest of the Azores is producing a large
area of gale-force winds with maximum winds near 60 mph. Shower
activity is currently limited near the center, but this low could
gradually acquire some subtropical or tropical characteristics
during the next couple of days while it moves southeastward and then
eastward into the eastern subtropical Atlantic. Regardless of
subtropical or tropical cyclone formation, this system is expected
to produce hazardous marine conditions over portions of the central
and eastern Atlantic for the next few days. For additional
information, see High Seas Forecasts issued by the National Weather
Service. The next Special Tropical Weather Outlook on this system
will be issued by 2 PM EST Tuesday.

Convection looking pretty impressive this morning. Fingers crossed for it eventually losing frontal characteristics and confirming a bizarro-world early January start to BOTH of the hemisphere's seasons. Only other recent time I can think of similar to this if that were to happen is 1992 (Ekeka CPAC in late January and subtropical storm in the Atlantic in April)

Kind of has the look
