DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Erin was located
near latitude 32.2 North, longitude 73.2 West. Erin is moving toward
the north near 14 mph (22 km/h). A turn toward the north-northeast
is expected tonight, followed by a faster motion toward the
northeast and east-northeast by Thursday and Friday. On the
forecast track, the center of Erin will move over the western
Atlantic between the U.S. east coast and Bermuda tonight and early
Friday, and then pass south of Atlantic Canada Friday and Saturday.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds are near 110 mph (175 km/h)
with higher gusts. Some strengthening is possible during the next
day or so, and Erin could become a major hurricane again tonight.
Weakening is likely to begin by Friday, but Erin is forecast to
remain a hurricane into the weekend.

Erin is a large hurricane. Hurricane-force winds extend outward up
to 105 miles (165 km) from the center and tropical-storm-force
winds extend outward up to 265 miles (425 km). During the past few
hours, NOAA buoy 41002, located west of the center, has reported
sustained winds of 62 mph (100 km/h) and a wind gust of 72 mph (115 km/h).

The minimum central pressure just reported by the Hurricane Hunter
aircraft is 941 mb (27.79 inches).

HAZARDS AFFECTING LAND
----------------------
Key messages for Erin can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC.

WIND: Tropical storm conditions are expected over portions of the
North Carolina Outer Banks and the Virginia coastline beginning
in the next several hours. Elsewhere along the mid-Atlantic and
southern New England coast, wind gusts to tropical storm force are
likely Thursday through early Friday. Tropical storm conditions are
possible on Bermuda Thursday and Friday.

SURF: Swells generated by Erin will affect the Bahamas, Bermuda,
the east coast of the United States, and Atlantic Canada during the
next several days. These rough ocean conditions are expected to
cause life-threatening surf and rip currents. Please consult
products from your local weather forecast office for more information.

A depiction of rip current risk for the United States can be found
at: hurricanes.gov/graphics_at5.shtml?ripCurrents

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Cape Lookout to Duck, North Carolina...2 to 4 ft

The deepest water will occur along the immediate coast where the
surge will be accompanied by large and dangerous waves.
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by
your local National Weather Service forecast office.

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at5.shtml?peakSurge.

RAINFALL: The outer bands of Erin may bring up to 1 inch of rainfall
to the Outer Banks of North Carolina this afternoon into Thursday.

For a complete depiction of forecast rainfall and flash flooding
associated with Erin, please see the National Weather Service Storm
Total Rainfall Graphic, available at
hurricanes.gov/graphics_at5.shtml?rainqpf
