Non-Tropical Low in Central Atlantic (Is Invest 96L)

[cycloneye]

A non-tropical low pressure system with storm-force winds is located
about 200 miles south of Cape Hatteras, North Carolina. This system
is forecast to move east-northeastward over the next few days and
could gradually acquire some subtropical characteristics as it moves
across the subtropical Atlantic ocean along the warm Gulf Stream
current. For more information on this system, including storm and
coastal flood warnings, see products issued by your local National
Weather Service office and High Seas Forecasts issued by the
National Weather Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

Adria maybe? Would suck a lot if we ended the season with the whole list exhausted but not have a an aux storm with it.

18z GFS turns this into a bona-fide TC/STC in a few days, and even shows regeneration after getting squished by a front in the medium-long range. The 18z ICON also tries to make it a STC, but it looks non-tropical through the entire run.

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

1. A non-tropical low pressure system with storm-force winds is
located nearly 400 hundred miles east of Cape Hatteras, North
Carolina and is forecast to move east-northeastward during the next
several days. By mid-week, the system could gradually lose its
frontal characteristics over the subtropical Atlantic Ocean and
briefly acquire some subtropical characteristics before merging with
a larger low pressure system, over the north-central Atlantic.
However, the chance of subtropical cyclone formation appears to be
be decreasing. For more information on this system, including
storm and coastal flood warnings, see products issued by your local
National Weather Service office and High Seas Forecasts issued by
the National Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...10 percent.

Yup, just as expected lol.

We're well into the occluded low naming season...

If it gets pushed south and takes on tropical characteristics, so be it. Wanda was clearly a warm core for a very long time.

Looks like Wanda will be the last name of the 2021 season.

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

1. A non-tropical low pressure system with storm-force winds is located
several hundred miles east of Cape Hatteras, North Carolina. This
system now appears unlikely to lose its frontal structure and
acquire subtropical characteristics during the next few days while
it moves eastward to east-northeastward at around 15 mph. By late
this week, the low is expected to merge with a larger extratropical
low pressure system over the north-central Atlantic Ocean. For more
information on this system, including storm warnings, see High Seas
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.

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

1. Showers and thunderstorms associated with a storm-force non-tropical
low centered about 300 miles northeast of Bermuda have become better
organized since this morning. As the low moves eastward and then
northeastward during the next couple of days, some additional
development is possible while the system remains over relatively
warm water south of the Gulf Stream. After that time, the system is
forecast to be absorbed by another non-tropical low. Additional
information on this system can be found in High Seas forecasts
issued by the National Weather Service.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
