HURRICANE NEWS AND NEW EVACUATIONS
Good evening everyone. Some brand new information today. As of 11 AM EDT, mandatory evacuations have been ordered from low lying coastlines along the Virginia coast including the Virginia coastal areas of the Chesapeake Bay. Over 450,000 people live in low lying coastal areas in southeast Virginia. This mandatory evacuation includes Virginia Beach east of Pacific Avenue. The ocean front hotels are not a good place to be. In addition a mandatory evacuation continues throughout the outer banks of North Carolina and will continue into this evening. The biggest concern is the hurricane moving onshore at times of high tide Thursday afternoon, which would make the high tides already in place even higher. A dangerous situation indeed.
The governors of 4 states, North Carolina, Virginia, Delaware and Maryland have all declared state of emergencies well ahead of the storm. That means the national guard, state police, and dept of transportation will be on full alert status during the entire storm.
HURRICANE/TROPICAL STORM ADVISORIES
A hurricane warning remains in effect for the entire North Carolina coast from Cape Fear northward up to Chicoteague, Virginia.
