The realm of possibilities continues to range from Sandy escaping out to sea,
with nothing more than blustery, much cooler air sweeping in, to a dynamic
storm turning inland packing coastal flooding, flooding rainfall, high winds,
downed trees, power outages, travel mayhem and even Appalachian snow.
a weather map standpoint, the worst-case scenario is for Sandy as a hurricane
or hybrid storm to be captured as chilly air and strong upper-level winds join
in from North America. Meteorologists refer to this as an atmospheric
from eastern North Carolina to Maine and Nova Scotia need to keep their guard
up in case the worst-case scenario occurs.
example of such an event includes 1991's Perfect Storm. However, as bad as it
was, the worst of it remained offshore. Other October storms with a real bad
attitude, which hugged the coast, were 1878's Gale, 1923's unnamed storm and
the assumption that the storm turns inland is correct, the worst conditions
would be near and well northeast of the storm center as it moves inland. This
is where the strongest winds, heaviest rain and greatest storm surge would be
due to the onshore flow of high-speed moisture.
example, a storm with hurricane strength turning inland over New York City
would have tremendous impact from New York to Boston and inland to Albany, but
there would likely be a sweep of dry air, gusty offshore winds and minimal
concerns farther south from Philadelphia to Washington, D.C.
is another scenario that is more common. Quite simply, tropical systems and
non-tropical systems do not like to join forces very often. In this case, Sandy
would be more of a side show.
scenario would generate a more common nor'easter nearby but offshore with
significant, but far less-damaging impact. In this case, Sandy itself would not
be drawn in but would escape out to sea and some of its moisture would feed the
storm. Drenching rain, gusty winds and minor flooding problems would focus on
New England and neighboring Canada.
of the scenarios, a sure bet with the weather pattern this weekend into early
next week will be the northward spread of rough surf and rip currents along the
Atlantic coast and building seas offshore. Seas offshore would reach 30 feet or
higher in the proximity of Sandy.
