Hurricane Sandy: Part IV

Good evening (Or should I say good morning?)

Wow. I don’t even know where to begin. Let me start by saying this: Despite the fact that Hurricane Sandy has transitioned to an extra-tropical cyclone,meaning it has gone from a warm core barotropic cyclone (a cyclone characterized by a lack of fronts) to a cold core baroclinic cyclone (a cyclone characterized by distinct airmasses or fronts), it is still a very powerful storm with life-threatening impacts. This is simply a scientific classification; Sandy is still as strong as it was when it made landfall. However, expect continued weakening over the next 24-36 hours. For more info on that, check out this link:

Onto the impacts: Take this into perspective. The pressure differences between where I am in Bloomington Indiana and where Sandy is, have created wind gusts of up to 50 mph. Waves on Lake Michigan are expected to climb to nearly 25 feet in Porter and Lake County Indiana. This storm is nearly 800 miles away, but its impacts are even being felt in Northern and Central Indiana.

The next thing of note is the countless reports of damage and destruction so far. From the sound of it, New York City has been hit very hard. In the morning, when the sun rises, we will have a better idea of how bad the damage is. And let me say this: It will be very bad. Flooding of the MTA Subway system and throughout lower Manhattan has been historic. Compared to Hurricane Donna of 1960, the crest of the water levels is almost 4 feet higher, shattering the old record of 10 feet. One thing I read about on Twitter this evening, mentioned how social media is affected our ability to relay information much better than we could during Katrina. Katrina was all the way back in 2005, when Facebook was still just a baby. This ability to spread and distribute vital information and news on the current state of damage is very important. It is without a doubt saving lives. Continue to spread word and get any images that you have of damage or flooding, but please do it safely.

Continue to ride this storm out and stay safe. I will have more updates on damage and impacts in the morning. I am sure there will be a lot of information when the sun comes up.

Until then, stay SAFE and see you in the morning.
