DESCRIPTION: HLSAKQ This product covers CENTRAL AND EASTERN VIRGINIA...NORTHEAST NORTH CAROLINA...AND THE LOWER MARYLAND EASTERN SHORE **ERIN MOVING AWAY FROM THE NORTH CAROLINA COAST** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - All watches and warnings have been canceled * CURRENT WATCHES AND WARNINGS: - None * STORM INFORMATION: - About 390 miles east-southeast of Ocean City MD or about 440 miles east of Norfolk VA - 36.8N 68.2W - Storm Intensity 100 mph - Movement Northeast or 50 degrees at 20 mph SITUATION OVERVIEW ------------------ Hurricane Erin, currently about 420 miles ENE of Cape Hatteras, NC, continues to move northeast away from the coast. Erin will continue to move northeastward with the center of the storm tracking well offshore of the Mid-Atlantic coast. The tropical storm force wind threat has come to an end for the local area with Erin moving further away. Erin will continue to bring high surf, significant dune and beach erosion and moderate to locally major tidal flooding to the area. Seas of 12 to 18 feet over the coastal waters remain possible this evening into tonight which will allow for significant beach and dune erosion for the coast especially around the times of high tide. In addition, moderate to locally major coastal flooding is expected during the high tide cycle this evening and tonight with inundation of 1 to 3 feet above normally high ground. A Coastal Flood Warning remains in effect for the Atlantic coast from Corolla, NC to Ocean City, MD, areas adjacent to the Chesapeake Bay from Windmill Point south, tidal portions of the James, York, and Rappahannock Rivers as well as adjacent estuaries. A Coastal Flood Warning is also in effect for areas adjacent to the Chesapeake Bay north of Windmill Point through the bay side of the lower Maryland Eastern Shore, and the southern shore of the Potomac River, as well as adjacent estuaries. POTENTIAL IMPACTS ----------------- * SURGE: A Coastal Flood Warning remains in effect for areas along the Atlantic coast, Chesapeake Bay, and tidal rivers. * OTHER COASTAL HAZARDS: Along the Atlantic coast from Fenwick Island Delaware to Duck North Carolina, expect waves to build to 12 to 18 ft today. These large waves combined with increased water levels will likely allow for significant beach and dune erosion. There is a high risk of rip currents along the shoreline through Friday, and a high risk of rip currents will likely continue into the weekend. * WIND: Little to no additional impacts are anticipated at this time. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: If you are prone to coastal flooding or ocean overwash be prepared for the possibility of a quick rise in water levels. Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information.

A hole punch cloud is an unusual occurrence when a disk-shaped
hole appears in a cirrostratus, cirrocumulus, or altocumulus cloud.
When part of the cloud forms ice crystals, water droplets in the surrounding area
of the cloud evaporate. The effect of this process produces a large elliptical
gap in the cloud. The hole punch cloud formation is rare, but it is not specific
to any geographic area.
Other names which have been used to describe this phenomena include fallstreak hole,
skypunch, and cloud hole.

A nimbostratus cloud is similar to a stratus cloud in its formless,
smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud,
because it is thicker.
Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat
of moderate to heavy precipitation. In some cases, the precipitation may evaporate
before reaching the ground, a phenomenon known as virga.
