Where did this come from?

[Hammy]

someone post this model page

[Tireman4]

Just poof..

[wxman57]

It's just a weak low on the trailing end of a cold front east of Bermuda. It will head north toward the Canadian maritimes.

[TheStormExpert]

Doesn't surprise me! Noticed when the 12z Euro ran it developed something weak just East or Southeast of Bermuda in 48hrs. Was wondering earlier if it was worth mentioning. Expect the NHC to mention it on their 8pm TWO.

[Ntxw]

It's just a weak low on the trailing end of a cold front east of Bermuda. It will head north toward the Canadian maritimes.

Same disturbed area of frontal boundary that brought extra shear to knockout what was left of Fred?

[TheStormExpert]

No model thread so I'll just put it here for now. Someone can move it if they want.

What the Euro was showing on it's 12z run.

48hrs.


72hrs.

[Hurricaneman]

Could be a storm threat for Bermuda so they need to watch this system

Uhh, which one is the tropical cyclone again?

[Hurricaneman]

Uhh, which one is the tropical cyclone again?

If I knew nothing I would have said the one on the right but Grace is the one on the left thats why I think that 92L has a lot of potential to even become a strong tropical storm for Bermuda thats why they need to watch

NHC mentions the area.

[TropicalAnalystwx13]

A concentrated area of cloudiness and showers has developed over the
central Atlantic about 250 miles east-southeast of Bermuda.
Environmental conditions are expected to become somewhat favorable
for development during the next few days while the system remains
nearly stationary for the next day or so, and then moves northward
at 5 to 10 mph by Wednesday.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...20 percent

[Extratropical94]

An area of cloudiness and showers located about 250 miles
east-southeast of Bermuda are associated with a trough of low
pressure. Environmental conditions are expected to become
somewhat conducive for development during the next few days while
the system remains nearly stationary for the next day or so, and
then moves northward at 5 to 10 mph by Wednesday.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...low...30 percent

8 AM:

An area of cloudiness and showers located about 300 miles east-
southeast of Bermuda is associated with a broad area of low
pressure. Environmental conditions are expected to become more
conducive for development during the next couple of days while the
system remains nearly stationary for the next day or so, and then
moves northward at 5 to 10 mph by Wednesday.
* Formation chance through 48 hours...medium...40 percent
* Formation chance through 5 days...medium...40 percent

[Extratropical94]

An area of cloudiness and showers located about 250 miles east-
southeast of Bermuda is associated with a broad area of low
pressure. Strong upper-level winds are inhibiting the development
of this system, but these winds could become more conducive during
the next couple of days. The low is expected to remain nearly
stationary today and tonight, and then move northward at 5 to 10 mph
on Wednesday and Thursday. By Friday, the system should be
absorbed by a large extratropical cyclone.
* Formation chance through 48 hours...medium...40 percent
* Formation chance through 5 days...medium...40 percent
