Hurricane Sandy is a big-ass storm
Overnight, Hurricane Sandy experienced a stunning increase in size and intensity. Sandy is presently heading for the western and central Bahamas and will brush southeast Florida. Then comes the likely encounter with the Mid-Atlantic and/or Northeast U.S. Sunday-Wednesday.
The latest National Hurricane Center indicates the maximum sustained winds are 105 mph, and tropical storm force winds extend 140 miles out from the center. Sandy is a strong category 2 hurricane.
While Sandy was forecast to stengthen to a hurricane prior to making landfall on Jamaica, it was not expected to rapidly intensify in the 125 miles of ocean between Jamaica and eastern Cuba.
Despite going over fairly high mountains in Jamaica and being so close to fairly high mountains in Cuba, Sandy’s central pressure plummeted 14 mb in 3 hours and winds increased by 30 mph in about 7 hours after it left the Jamaican coast.
Although the size and intensity of hurricanes aren’t well correlated, not only has Sandy intensified over the past day, it has also grown and is now an enormous circulation with a diameter of about 1500 miles. In other words, locations as far as 700-800 miles away from the center are measuring Sandy-related pressure drops, seeing Sandy-related clouds, and feeling Sandy-related winds.
