Well this certainly is a surprise – but alas we have the first subtropical storm of the year. Instead of it being in June it just happened to occur two weeks into the new year. This system is a hybrid mix between extratropical and fully tropical – so subtropical. Satellite data indicates a small area of tropical storm force winds exist with this system. Alex is located 785 miles southwest of the Azores and will approach that area on Friday. This system is not a sign that we’re expecting a busy atlantic hurricane season. These just happen to occur out of season every few years. We’ll be rid of it in a few days.
