I think Irene has solved the Caribbean puzzle as it's going to escape just north of Hispaniola, so all my earlier doubts have faded. Now, I see a real chance that Irene will become a major hurricane over the Bahamas. There's still a ton of uncertainty in the models regarding how much will that subtropical ridge over Bermuda break later this week, which will mean everything in forecasting Irene's northward turn. Irene could still miss the East Coast entirely if it curves northward sooner than expected due to a rapid breakdown of the ridge, so I can't predict a landfall location with good confidence yet. However, the odds of a United States landfall have gone up dramatically in my mind.
I urge everyone from FL to NC to monitor this hurricane closely and prepare for any watches. Now, I hope you all realize how much I hate hyping up storms too soon due to all the evidence you've seen from past storms this year. So, I hope it means something to you all that I'm actually turning on my "red mode" in my mind this morning.
