A large, non-tropical low in the north-central Atlantic that has been undergoing subtropical transition for the past few days has almost acquired enough subtropical characteristics for to feel comfortable issuing advisories on. This system has been tagged "Invest 95L."
Unlike the unnamed subtropical storm which came inland this past week along the Carolinas, 95L is clearly already independent of its parent fronts, and a significant amount of splotchy thunderstorms have now wrapped completely around the center of circulation, outward a good distance particularly within one very thick arc and then one smaller arc closer to the LLC, in a manner similar to, but not yet as symmetrical, as was the case with Subtropical Storm Andrea (2007).
This system is currently traveling over SSTs in a range of 23-25 C, which is plenty warm for continued slow development, and 95L could easily become a named storm within the next day or two.
"95L" had been drifting to the southwest (now moving along nearly due west during late morning and afternoon Sunday). At this time, models anticipate a reversal of course, and an eventual recurvature to the NE and ENE. It is possible that should high pressure start build back in to the east and northeast of Hurricane Kyle a little faster, 95's forecast imminent course correction may not take place as expected, or perhaps not take place at all. But for now, it is a curiosity and shipping hazard.

Invest 95L is now Subtropical Storm Laura and more info can be found on the Main Page.
As of this morning (Monday) Laura continues to acquire more tropical characteristics.
