Hybrid Storm System Update 11/10


Tropical Storm Sean has developed over the Atlantic. This was a hybrid storm initially that developed off of a Mid-latitude Cyclone that acquired Tropical Storm characteristics over the warm subtropical waters of the Atlantic off the Southeastern US coast, north of the greater Antilles. An elevated rip current threat and rough surf can be expected from the east coast of Florida to the outer banks of North Carolina. This system is forecast to loose its tropical characteristics, becoming extra tropical as it moves into the cooler waters of the north Atlantic Ocean. A part of this storm's energy will be absorbed by a strong cold front that will move east on Thursday November 10th. This phase between systems will likely enhance precipitation over eastern New England on Veterans Day this Friday November 11. Tropical Storm Sean is the 18th named system so far to spawn from the 2011 Atlantic Hurricane Season.
