Sandy shows intensity "flare"
As Sandy passed over a warm ribbon of water near 80F in the Gulf stream this morning, we see a significant "flare" of intensity in the storms central dense overcast.
Sandy is now a massive well organized storm with a nasty and well defined center. The IR loop even shows signs that Sandy has once again attempted to develop an eye.

Details from the 11 am EDT NHC discussion.
SANDY IS CURRENTLY TRAVERSING A NARROW RIDGE OF WARM SSTS AROUND 27C...WHICH ARE ASSOCIATED WITH THE GULF STREAM. THIS EXTRA LOW-LEVEL HEAT INPUT HAS LIKELY CONTRIBUTED TO THE RECENT INCREASE IN CONVECTION AROUND THE EYE.
At 90 mph, Sandy is a strong Category 1 storm. With an incredible central pressure of 943 millibars, Sandy has deepened significantly. 943 millibars is the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale.
Since Sandy is no longer purely a hurricane and is transitioning to extra tropical, we can see this kind of pressure...without associated Cat 4 wind speeds.
Still Sandy is a very dangerous storm, and the worst effects still lie ahead in the next 24 to 48 hours.
Sandy will make landfall on the Jersey Coast late tonight.
