Katrina was a August hurricane in the southern part of the US where the weather was quite warm before and after the hurricane. One of the big challenges for those that survived without power was to stay cool.
Sandy on the other hand was a winter hurricane in the norther part of the country, where cool fall weather is quite common. The challenge for the survivors will be to stay warm.
Below is the Unisys GFSX model forecast for the next 48 hours on the 5th. By Wednesday the 7th it will be even colder, with winds from the north. By Sunday the 11th it is colder yet. It does not start warming until Monday the 12th. This is going to be real challenge for those without heat and light.
The 1000 mb chart also shows near surface weather conditions. The parameters plotted are 1000 mb temperature in Celsius (in color contours), convergence (black lines, interval=2, shaded > 0), 1000 mb dewpoints in Celsius (colored lines, interval=5, bold orange=20, bold white=15, bold red=0, bold magenta=-15, bold gray=-30) and winds plotted as vectors.
On Thursday the 5th the rain starts with some snow in the higher elevations..
The sea level pressure and precipitation forecast chart includes three parameters: sea level pressure (cyan lines), 1000-500 mb thickness (brown dotted lines, 5100, 5400, 5700 solid lines) and quantitative precipitation (color contours).

Life in New York, New Jersey and surrounding region is going to be quite difficult for the survivors, unless the power and lights get turned on real soon now!
