Non-Tropical Low in North-Central Atlantic (Is Invest 90L)

[cycloneye]

8 AM TWO:

A non-tropical low is forecast to form this weekend between Bermuda
and the Azores. After that time, conditions are expected to be
favorable for subtropical or tropical cyclone formation while the
low meanders over the north Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

Is this related to Florence's remnants?

This has a good chance to become Kirk, potentially the sixth subtropical storm of the year. And unlike the other subtropical storms, this one may actually have a chance to last a while and potentially become a hurricane.

2 PM TWO:

A non-tropical low is forecast to form this weekend between Bermuda
and the Azores. After that time, conditions are expected to be
favorable for subtropical or tropical cyclone formation while the
low meanders over the north Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

8 PM TWO:

A non-tropical low pressure system is forecast to develop this
weekend over the central subtropical Atlantic Ocean between Bermuda
and the Azores. After that time, conditions are expected to become
favorable for the formation of a subtropical or tropical cyclone
while the low meanders over the central Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent

[Kazmit]

Looks like there's a decent chance we could see two storms by the end of the month with this and 97L.

8 AM TWO:

A non-tropical low pressure system is forecast to develop by Friday
night over the central subtropical Atlantic Ocean between Bermuda
and the Azores. Conditions are expected to be conducive for the low
to acquire some subtropical or tropical characteristics, and a
subtropical or tropical cyclone could form over the weekend or early
next week while the low meanders over the central Atlantic Ocean.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.

2 PM TWO:

Another non-tropical low pressure system is forecast to develop by
Friday night over the central subtropical Atlantic Ocean between
Bermuda and the Azores. Conditions are expected to be conducive for
the low to acquire some subtropical or tropical characteristics, and
a subtropical or tropical cyclone could form late this weekend or
early next week while the low meanders over the central Atlantic
Ocean.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.

8 PM TWO:

Another non-tropical low pressure system is forecast to develop
by Friday night over the central subtropical Atlantic Ocean midway
between Bermuda and the Azores. Conditions are expected to be
conducive for the low to acquire some subtropical or tropical
characteristics, and a subtropical or tropical cyclone could form
late this weekend or early next week while the low meanders over the
central Atlantic Ocean.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...60 percent.

Will this low originate from the same trough (which is also what's left of Florence) that spawned 98L?

[EquusStorm]

Looking at model runs, that looks to be the case; assuming 98L grows, it's intriguing watching a hurricane spawn two more of itself in its dying gasps

8 AM TWO:

A non-tropical low pressure system is forecast to develop tonight
over the central subtropical Atlantic Ocean midway between Bermuda
and the Azores. Conditions are expected to be conducive for the low
to acquire subtropical or tropical characteristics, and a
subtropical or tropical cyclone is expected to form late this
weekend or early next week while the low meanders over the central
Atlantic Ocean.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...high...70 percent.

2 PM TWO:

A non-tropical low pressure system is forecast to develop tonight
or on Saturday over the central subtropical Atlantic Ocean midway
between Bermuda and the Azores. Conditions are expected to be
conducive for the low to acquire subtropical or tropical
characteristics, and a subtropical or tropical cyclone is likely
to form late this weekend or early next week while the low meanders
over the central Atlantic Ocean.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...high...70 percent

[Abdullah]

European Model brings this up quite high.

Is this related to Florence's remnants?

At least at the upper levels. I would consider 98L to be the ex-Florence LLC, but there will be debate for sure.

[cycloneye]

8 PM TWO:

A non-tropical low pressure system is expected to develop early this
weekend over the north-central Atlantic Ocean, midway between
Bermuda and the Azores. Conditions are expected to be conducive for
the low to acquire subtropical or tropical characteristics, and a
subtropical or tropical cyclone is likely to form late this weekend
or early next week while the low meanders over the central Atlantic
Ocean.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...high...70 percent.

[Ptarmigan]

It is this part of the Atlantic that has been favorable for tropical development this season.

8 AM TWO:

3. Satellite imagery indicates that a non-tropical low pressure system
is forming along a frontal boundary about 900 miles west-southwest
of the Azores. Conditions are expected to become conducive for the
low to acquire subtropical or tropical characteristics, and a
subtropical or tropical cyclone is likely to form by early next week
while the low meanders over the central Atlantic Ocean. For more
information on this system, see High Seas Forecasts issued by the
National Weather Service.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent

It will be facinating to watch how it evolves.

Because both the GFS and Euro show it meandering around for the next 10 days or so it could still put up some nice ACE numbers once it gets subtropical characteristics.
