... Hurricane Warning remains in effect...
... Probability of tropical storm/hurricane conditions...
the chance for hurricane conditions at this time is 3 to
10 percent. Also... the chance for tropical storm conditions at
this time is up to 91 percent.
... Winds...
as Hurricane Irene approaches... sustained tropical storm force
winds are expected to begin late this evening... with hurricane
force winds developing early Sunday morning. Maximum winds are
forecast to be in the 55 to 75 mph range with gusts up to 85 mph.
Damaging winds are likely. Homes may have damage to shingles...
siding... gutters and windows... especially if these items are not
properly secured. Loose outdoor items will become airborne...
causing additional damage and possible injury. Power lines will
be knocked down by falling trees... resulting in widespread power
outages. Many large branches of trees will be snapped... and a
numerous trees will be uprooted.
... Tornadoes...
isolated tornadoes are possible across Long Island... coastal
Connecticut... and the New York City Metro area as intense rain
bands move in from the south tonight.
... Storm surge and storm tide...
storm surge is highly dependent on track... intensity... and speed
of the storm as it approaches the coast. The combined effects of
storm surge and storm tide pose a serious threat with several
feet of water inundation possible along coastal locations.
Based on the forecast track of Hurricane Irene... there is
potential for 4 to 8 feet of surge across western Long Island
Sound and New York Harbor... with 3 to 5 ft of surge along the
South Shore bays of Long Island and New York City... Peconic and
gardiners bays... and eastern Long Island from early Sunday
morning into early Sunday afternoon. These tidal conditions will
be aggravated by accompanying large... destructive... and life
threatening waves on top of the storm surge.
High tide across New York Harbor and the South Shore of western
Long Island is around 8 am Sunday. In a worst case scenario...
water levels of 8 to 10 ft above msl are possible.
High tide across western Long Island Sound is around 11 am
Sunday. In a worst case scenario... water levels of 10 to 11 ft
above msl are possible.
High tide across eastern Long Island Sound is around 9 am Sunday.
In a worst case scenario... water levels of 7 to 8 ft above msl
are possible.
There is a 10 percent chance of the worst case scenario.
... Inland flooding...
a Flood Watch is in effect for the entire area. Rainfall amounts
of 6 to 12 inches with locally higher amounts are expected. See
the latest forecast for the most updated information. Listen for
possible flood warnings for your location... and be ready to act
if flooding rains occur.
... Coastal hazards...
increasingly large swells arriving from Hurricane Irene will
create high surf... significant beach erosion and washovers along
the Atlantic facing coastline tonight into Monday.
Significant beach erosion is also likely along the coastline of
Long Island Sound and Peconic and gardiners bays due to the surge
and battering surf.
... Rip currents...
dangerous and life threatening rip currents are expected through
Monday.
