Now I thought that having little rainfall in May was an indicator that El Nino was not strong or not present, which would lead to increased tropical activity. The Bermuda High was a directional steering thing which doesn't affect activity only the direction in which it travels. I didn't think that rainfall and El Nino affected the Bermuda High. Make sense or am I really off?
Well, if the Bermuda High is too strong, it can seriously inhibit the development of weaker systems. I believe that an overly strong BH is sometimes referred to as a "fast ridge". The circulations in developing systems simply can't properly align when the weather system is moving off to the west too quickly. Overall though, the BH probably isn't a major factor as far as activity levels go. Steering-wise, it is quite important.
Also, in Florida, May is part of the dry season. El Nino tends to increase precipitation and storminess in Florida during the dry season. However, we typically see a decrease in storms in FL caused by low pressure areas associated with the jet stream later in the dry season (hence a more summer-like pattern by May/June).
