Re: gearing up for sandy

This storm has a very high potential to SUCK water out of the Chesapeake, possibly to record low water ---- I'd haul my boat, I already did.

With the storm coming north close to the coast and crossing the mid DelMarVa peninsula, the strongest winds will be from N-NE, and that will 'suck & push' a LOT of water out of the Chesapeake. In the 1950s such a storm with essentially the same track dropped the Ches. by ~5-6+ft !!! Once the storm goes inland into central Penna then the wind will shift to the W-NW and continue to push water out of the Cape Charles - Cape Henry entrance to the bay ... depending on the wind strength at Norfolk; since this is a WIDE area storm that scenario seems quite likely.
H. Isabel came ashore south of C. Henry and therefore 'loaded' the bay; this time the predictions are for coming ashore north of Cape Charles ... and that usually 'sucks' the bay lower.

Method for determining wind direction during Hurricane: raise your right arm to the horizontal then swing it back as far as you can (~120 from your nose), point to the 'center of storm' with your right index finger .... the expected wind will be straight into your face.

The combination of the Hurricane and its meeting and 'combining' with a trough coming from the west (an additional 'weather bomb') may keep a very strong NW flow / gales for several days ... keeping the Ches. at record low levels.
