Weather Channel meterologist Stu Ostro is raving over Hurricane Sandy:
– History is being written as an extreme weather event continues to unfold, one which will occupy a place in the annals of weather history as one of the most extraordinary to have affected the United States.
– REGARDLESS OF WHAT THE OFFICIAL DESIGNATION IS NOW OR AT/AFTER LANDFALL — HURRICANE (INCLUDING IF “ONLY” A CATEGORY ONE), TROPICAL STORM, POST-TROPICAL, EXTRATROPICAL, WHATEVER — OR WHAT TYPE OF WARNINGS ARE ISSUED BY THE NATIONAL WEATHER SERVICE AND NATIONAL HURRICANE CENTER — PEOPLE IN THE PATH OF THIS STORM NEED TO HEED THE THREAT IT POSES WITH UTMOST URGENCY…
– With Sandy having already brought severe impacts to the Caribbean Islands and a portion of the Bahamas, and severe erosion to some beaches on the east coast of Florida, it is now poised to strike the northeast United States with a combination of track, size, structure and strength that is unprecedented in the known historical record there…
– A meteorologically mind-boggling combination of ingredients is coming together: one of the largest expanses of tropical storm (gale) force winds on record with a tropical or subtropical cyclone in the Atlantic or for that matter anywhere else in the world; a track of the center making a sharp left turn in direction of movement toward New Jersey in a way that is unprecedented in the historical database, as it gets blocked from moving out to sea by a pattern that includes an exceptionally strong ridge of high pressure aloft near Greenland; a “warm-core” tropical cyclone embedded within a larger, nor’easter-like circulation; and eventually tropical moisture and arctic air combining to produce heavy snow in interior high elevations. This is an extraordinary situation, and I am not prone to hyperbole.
– That gigantic size is a crucially important aspect of this storm. The massive breadth of its strong winds will produce a much wider scope of impacts than if it were a tiny system, and some of them will extend very far inland. A cyclone with the same maximum sustained velocities (borderline tropical storm / hurricane) but with a very small diameter of tropical storm / gale force winds would not present nearly the same level of threat or expected effects. Unfortunately, that’s not the case. This one’s size, threat, and expected impacts are immense.
