As of 4 AM Sun...Coastal Flood Warnings and Advisories remain on
track this morning with a coastal low meandering off the
southern NC coast. Main forecast change this morning is an
increase in both wind speed and duration this morning into this
afternoon, and as a result, slightly higher water
levels/inundation is expected.
The highest concern will be along oceanside areas of OBX Dare
county north of Cape Hatteras where the combination of wind
surge, high astronomical tides, and wave run up will lead to the
potential for major coastal flooding (3-5 ft AGL) with this
afternoon`s (~12 pm) high tide. This includes already vulnerable
areas like Buxton, Rodanthe, and Pea Island, but significant
overwash impacts could be seen north of Oregon Inlet as well.

The main impacts remain the coastal hazards, in the form of wind and
coastal flooding (see section below for more coastal flooding info).
E-NE winds will increase substantially over the next few hours as
the low inches N and will be greatest along and north of the
leading edge of the coastal warm front. Peak winds occur from
around sunrise into the early-mid afternoon for NE NC and SE VA,
with the peak a bit later (this afternoon into the evening) for
locations adjacent to the middle and northern Chesapeake Bay
and the VA/MD Eastern Shore. Wind Advisories are in effect for
most areas near and just inland from the coastline for gusts of
40-50 mph, with High Wind Warnings for those zones immediately
bordering the ocean for gusts 50-55 mph (locally 60 mph). Note
the High Wind Warning was expanded to coastal Currituck County a
few hours ago, with it remaining in effect for VA Beach,
Northampton and Accomack Counties on the VA Eastern Shore, and
the MD beaches. Wind gusts inland average 25-35 mph. Breezy
conditions persist into tonight as the winds turn to the N with
the secondary low moving further NE.

Meanwhile, there is an increasing risk of moderate to major
coastal flooding impacts beginning today through Monday as a
coastal storm impacts the region. Guidance still varies in
potential outcomes of this storm with regard to severity of
coastal flood impacts locally, however we remain very concerned
about the potential for significant impacts from this storm
along our coasts. At this time, the greatest threat of impacts
are anticipated to occur along the Atlantic coasts of New Jersey
and Delaware, and Delaware Bay. A Coastal Flood Warning remains
in effect for Sunday through Monday.

Upton (NYC) :

Confidence is increasing in widespread moderate to major
coastal flooding for the this afternoon, and moreso the tonight
and possibly Monday afternoon high tide cycles along the
western Great South Bay as ENE-NE winds ramp up to marginal
storm force this afternoon into tonight. This will pose an
elevated threat to life and property. There is low potential for
major coastal flooding for Jamaica Bay with the Sunday Night
and Monday afternoon high tide cycles as well.
Elsewhere, confidence is high in areas of moderate coastal
flooding along N and E facing coastlines along Western LI Sound,
and twin forks of LI with combination of water levels reaching
marginal moderate flood levels, along with 3-6ft breaking wave
action. In addition, areas of moderate coastal flooding expected
along NY/NJ harbor, including the tidally affected rivers of NE
NJ, particularly the Hackensack River. Coastal flood warnings
are in effect for these areas.

(1,393 posts)Talking down Faux's attempts to compare this to Sandy, but saying it's like what the coastal area gets every 3 to 5 years, with the main threat being flooding from backed-up rivers/bays along the coast and some wind concerns there, especially this afternoon.
