|(Hurricane Irene on Radar)|
Irene has weakened to a category 2 storm tonight, and it looks like it will be able to stay that strength until landfall tomorrow at about 8am eastern. Although the National Hurricane Center is forecasting Irene to weaken further to a Cat 1 at landfall. Her maximum sustained winds are 100 mph and her pressure is 951 mb. That is still a pretty low pressure, so one logical thought on that is that the energy for a strong Cat 2 or low Cat 3 is there, but with the massive size of Irene, all that energy is being dispersed greatly. If she is able to contract her size a little bit, which it looks like she is doing, she will be able to remain a Cat 2 a landfall.
As for the rest of Irene's journey through the US coastline, she is still projected to reach New York City at hurricane strength. Given the dense population in her path, Irene could become one of the most costly hurricanes of all-time. Maybe even more expensive than Katrina in 2005, which most estimates have a about 100 billion dollars.
