90% of the time they recurve in the Bahamas unless you have a building high off the mid Atlantic building southward.They all seem to recurve year after year so when I see a storm coming in from the east I think recurve.

I will say this has sure covered some distance since yesterday. It is almost 20 degrees further west longitude.

Unless it has been shunted to the west, and that is never a good sign when that happens

I feel like the chance to hit Florida is always pretty low, but looking at past storms in this area at this timeframe, and even a week from now, we've had storms supposed to recurve go into the gulf, storms headed for the gulf suddenly recurve, and storms supposed to hit Florida stall or recurve slowly. The upper air forecasts past 5 days are just not reliable, so it's pure fantasy at this point. My bet IF this gets into the Bahamas is that it will be a nail biter until the last few days, similar to Dorian.
I would say by the middle of next week we will likely begin trend watching, G-IV will be out there and new data will be in pretty much every 12 hours.

90% is a bit too high and may not be appropriate to use this season in my opinion, when there hasn't been a deep trough pattern in the middle or western Atlantic so far which is what makes them recurve with certainty well away from the US.

Edit: EPS is forecasting a strong Bermuda ridge in the 5-10 day range, which I don't doubt much when is in that range and not past its 10 day range.

Long range steering is always obviously subject to change but I think there might be drifting or erratic movement in the Bahamas

The actual number is also not even close to 90%, its less than 50% for September. Most systems either slam into SFL or slip through into the Gulf.

FL is in the midst of the 2nd longest streak since 1850 without a strike from the East. This is why many think it’s a rare event. Historically, it is not.

I see what your saying but it ends up blocking the storm actually from what I can see.

The SW part of the gyre became dominant so the NHC shifted the x there instead of the wave around the CV islands

This looks like a prime season disturbance that persists yet struggles until it finds a pocket of favorability and takes off.

Does this 0Z EPS show significant # of members south through FL straits, or am I misinterpreting??

The 12z icon gets the coffee shakes with trying to find a center, but eventually settles on an area on the northwest side on Wednesday

Of course the path of least resistance is to the NE the ridge or should say “ Florida shield “ is blocking the westward movement at the end. That’s why I said some erratic or drifting is likely possible in the Bahamas.

My point is forget about going OTS by the looks of the EPS's 5-10 day range which most times is more correct than incorrect.
