On pictures such as this, can anyone clarify for me what the blue outline area is supposed to mean?
My first guess:
1 - This is the average-range for possible course trajectories of the centre of the hurricane.
That is, in this provided picture, projections are unsure if it will go up the west side or east side of Florida or anywhere in between.
Although the black line provided is the "most likely" with the information provided by this picture.
My second guess:
2 - The path of the hurricane within the blue area is more-or-less known (the black line), and the blue area is a "range of affected places" and possibly even showing the hurricane's projected growth along it's projected path?
Just wondering.
