Erin is a large hurricane. Hurricane-force winds extend outward up
to 90 miles (150 km) from the center and tropical-storm-force winds

Hunter observations 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
late today. 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.

Erin is expected to produce life-threatening surf and rip currents along the beaches of the Bahamas, much of the east coast of the U.S., Bermuda, and Atlantic Canada during the next several days. Beachgoers in those areas should follow advice from lifeguards, local authorities, and beach warning flags.

Storm surge flooding and tropical storm conditions are expected in the North Carolina Outer Banks beginning later today (20 August). The storm surge will be accompanied by large waves, leading to significant beach erosion and overwash, making some roads impassible.

Tropical storm conditions are expected on Thursday along the Virginia coast. Wind gusts to tropical storm force are likely along portions of the remainder of the U.S. Mid-Atlantic and southern New England coasts Thursday through early Friday.

Tropical storm conditions are possible on Bermuda on Thursday and Friday.

Observations from an Air Force Hurricane Hunter aircraft indicate that the hurricane has strengthened with peak 700 mb flight-level winds of 130 mph (115 knots) well to the east of the center. Using a reduction factor somewhat greater than that which would be used for eyewall winds, the intensity is set at 110 mph (95 knots) for this advisory. A dropsonde in the eye measured a surface pressure of 943 mb with 19 knot winds so the minimum central pressure has fallen to an estimated 941 mb. The hurricane has become better organized on satellite images this morning (20 August) with a symmetric-looking cloud pattern and numerous banding features. The eye has again become evident on the imagery and upper-level outflow is well-defined over all quadrants.
