The making of a 'perfect storm'
On Oct. 27, 1991, Hurricane Grace formed over the warm Atlantic Ocean southwest of Bermuda. The hurricane continued to grow over the warm waters of the Atlantic. By late on Oct. 28, the storm's 95 mph winds pushed 10 - 15 foot swells towards the coast of the Southeast USA.
Meanwhile, along the East Coast, the weather on Oct. 28 began to show improvement as high pressure moved in behind a cold front that moved off the coast earlier in the day. Along the eastward marching cold front, a new area of spinning low pressure developed just east of Nova Scotia.
On Oct. 29, Grace moved north along the front toward the stalling low-pressure area. Drawing Grace into its large circulation, the low-pressure system exploded into a major storm as it fed off the temperature difference provided by cold, dry air to its northwest clashing with the warmth and humidity from the remnants of Grace.
But it wasn't until this intense low-pressure area moved west toward the USA and then south and east to a point midway between Bermuda and New Jersey that it reached its maximum intensity. At this point on Oct. 30, sustained winds in the storm reached 70 mph, churning the Atlantic into a maelstrom of 40- to 80-foot waves, as reported by a weather buoy east of Long Island, N.Y. Other unsubstantiated observations reported winds and waves considerably higher, including a 101 foot wave measured by a buoy south of Nova Scotia, Canada.
During Oct. 30 - 31, the storm, still churning over the Atlantic, pounded much of eastern North America from North Carolina to Nova Scotia with waves 10 to 30 feet high. High tides along the coast were three to seven feet above normal, exacerbating the storm's effects. Heavy surf and extreme coastal flooding caused extensive damage along the New England and mid-Atlantic coast. Damage estimates in Massachusetts alone reached $100 million. Federal disaster areas were declared for seven counties in Massachusetts, five in Maine, and one in New Hampshire.Coastal flooding and raging seas raked places from Jamaica to Newfoundland, Canada.
The storm continued to churn the Atlantic for another two days before making landfall along the Nova Scotia coast November 2, 1991. As if its tumultuous life was not already enough, the immense mid-latitude storm evolved into a hurricane again when its center moved over the warm waters of the Gulf Stream Nov. 1. Hurricane hunters dispatched to the storm confirmed the transistion. But the National Hurricane Center decided not to name the hurricane for fear it would unnecessarily alarm coastal residents that had just weathered a major northeaster, as well as confuse people into thinking it might mean another major storm.

The Perfect Storm ?
I don't have a trained eye...
but all this rotating yellow and red looks bad !
And, I am not just speaking of Ivan.

Well if you need more proof that the NHC fudges the facts when it feels like it, there it is...as we see the forecast track finally start to pull to the west off the Florida peninsula. I guess they reached the point where it would just look too ridiculous to have Ivan make a 120° backwards loop.
