the only thing i disagree with is that the bermuda high will be strong. so far this spring there has been no sign of it at all
Not true - in March it was very strong. So strong that the GFS was showing low level pressure across the Atlantic Basin much like you would see in late August with huge ridging all over the Atlantic - not to mention that the eastern US warmer-than-normal winter was due to abnormally strong ridging all winter.
In April, the ridge has retreated.
I expect it to rear its ugly head in about 2 weeks and be very prominent most of hurricane season.
