Sandy is an increasing threat to morph into a major storm for the NE in the next few days as it moves north and interacts with a strong jet stream moving from the west and becoming stronger as it heads toward the east.{ } The combination still has a moderate risk (now 60% chance) of becoming the "Perfect Storm" of 2012.{ } Here is the latest track.{ } The "cone" is about the 70% probability of the path of Sandy and what will likely become a fierce hybrid coastal storm.{ }

The various simulations we look at are beginning to converge to this major storm coming ashore around the Delaware to New Jersey shore.{ }

Here is my discussion I did earlier of what is so unusual and reason for concern.{ }

It's a mix of a tropical/hurricane pattern getting combined with an amplifying winter-like jet stream pattern.{ } The makings of another "Perfect Storm"?{ } Very possible.
