It is not just about the SAL, the Ocean Surface Temps are tops and would allow development even with a thick layer of SAL on top of a storm.
But that's no news, we know that since Months.
It is anyways not about a number of disturbances or storms, it is Always about the One that could come too close to our home soil.
This Disturbance just left the African West Coast last evening, so nothing developed, nothing formed, no exact tracking of a still not formed system possible,
it is minimum a week away from the Caribbean, IF it would finally get a tracking towards the Caribbean in the first place.
That we have this season 7 days forecasts instead of the old 2--5 days forecasts, well, so far I do not see any advantage but many disadvantages,
because now people start to sh.it their pants an extra 2 days earlier and panic for nothing earlier than during prior seasons.
I think it would be best when NOAA would go back to the former 2-5 days forecast and keep the actual 7 days forecasts and the experimental longer range forecasts to themself for their professional use, but not to be made accessible for the public.
Hurricane Season takes 50% of the year, for the northern countries add to that the time for their heavy winter storms,
with far out long range forecasts people will be in panic mode a minimum 3/4 of the whole year and for what purpose??
Nobody will prepare for a storm more than 1 or maximum 2 days before the awaited hit of a storm, most preparations are done just a few hours prior to the awaited arrival of a storm.
Would someone prepare differently knowing a week ahead of time that there is a high probability that a storm may come close or right over the area where you live?
So far I only see huge disadvantages due long range storm forecasts, which also takes it's count on Tourism,
as the early forecasts let travelers start to discuss storms for the area of their hotel more ahead of time, without anything positive coning out of it, as people cancel vacations/flights for dates/times/locations where finally no storm will bother not a little bit.
Franklin and Lee been perfect examples of such Panic Mode.
To have knowledge about approaching storms 3 days ahead of time would be easily sufficient, 5 days a long range maximum forecast that should be provided, 7 days and more are a simple weather forecast over kill, no advantage for the public, just longer panic times and due that less life quality time for the public.
