Millions of residents up and down the US Eastern Seaboard from Virginia to New England are prepping for what could be a storm unlike any they've ever seen. Hurricane Sandy is forecast to interact with a trough of low pressure shortly, bend more westward and turn into an unprecedented extratropical system with TS force winds extending a huge 520 miles out from the center which means even if you're not in the immediate path of Sandy, you might still get quite some major impacts. One of multiple hazards here is the storm surge. With some areas forecast to receive a surge of 6 to 11 feet above ground level, coastal damage may be severe in lower portions of Manhattan and other adjacent parts of the NE US Coast and inland flooding may also get quite significant with isolated areas picking up over one foot according to forecasts and these forecasts have been consistent. And over inland higher elevations, we might be talking about something hardly ever seen with a tropical-like system...a heavy snowfall threat. Blizzard warnings are already up for much of West Virginia. Also prolonged winds of TS to even hurricane force near coastal areas of Delaware and New Jersey may lead up to extended power outages--winds itself aren't forecast to be as destructive as it is widespread. So if you've been waiting for a record-breaking extraordinary weather system unlike any we've seen before, but not particularly a catastrophe (although with all these expected impacts, major damage is a high likelihood in many areas), Sandy could go down as 21st Century's 'Storm Of The Century'. Quite a historical event underway with multiple hazards associated--and that's just a brief summary of what's to come.
