Discussion and 48-hour outlook

at 1100 am EDT...1500 UTC...the center of Tropical Storm Irene was
located near latitude 41.4 north...longitude 73.7 west. Irene is
moving toward the north-northeast near 26 mph...43 km/h...and this
motion with a little faster forward speed is expected over the next
day or so. On the forecast track...the center of Irene will move
over northern New England later today and over eastern Canada
tonight.

Maximum sustained winds are near 60 mph...95 km/h...with higher
gusts. Irene is forecast to weaken and become a Post-tropical
cyclone by tonight.

Tropical storm force winds extend outward up to 320 miles...520 km
from the center. A weatherflow station on Fire Island recently
reported sustained winds of 50 mph...80 km/h...with a gust to 63
mph...101 km/h.

Estimated minimum central pressure is 966 mb...28.53 inches.
Central Park in New York City reported 966.5 mb...28.54 as the
center passed this morning.

Hazards affecting land

storm surge...an extremely dangerous storm surge will raise water
levels by as much as 4 to 8 feet above ground level from western
portions of Long Island island sound eastward along the southern
coasts of Connecticut...Rhode Island...and Massachusetts. The
highest surges will occur near the upper parts of bays and inlets.
Near the coast...the surge will be accompanied by large...
destructive...and life-threatening waves. Higher than normal
astronomical tides are occurring this weekend. Coastal and river
flooding will be highest in areas where the peak surge occurs
around the time of high tide. Storm tide and surge values are very
location-specific...and users are urged to consult products issued
by their local National Weather Service offices. Water levels
along the New Jersey and Delaware coast including Delaware Bay will
subside today.

Rainfall...Irene is expected to produce total rainfall accumulations
of 4 to 8 inches...with isolated maximum amounts of 12 inches...
from northeastern Pennsylvania and northern New Jersey northward
into New York state and interior New England. These rains...
combined with heavy rains over the past few weeks...could
cause widespread flooding...life-threatening flash floods...and
significant uprooting of trees due to rain-softened grounds.

Wind...tropical storm force winds will spread northward into
northern New England and Atlantic Canada today. Winds affecting
the upper floors of high-rise buildings could be significantly
stronger than those near ground level.

Tornadoes...isolated tornadoes are possible over southern New
England this afternoon.
