Not too much changed with PTC#9 at the 11am advisory … will do a full update on the blog later today. Here’s the latest TAFB analysis … two things to note if you embiggen is the sort of oblong shape to the system, and the big high pressure system to the north. That high pressure ridge (think of the “H” as the top of a hill) is causing the storm to move around the left hand side – that is what is guiding the storm right now. So at the moment, the thinking is still that the system will stay weak, and should track south of Puerto Rico (but that may not help much if the winds and rain cross the Island). After that, hard to say at this point … stay tuned!
