The Atlantic coastline of Delaware is facing a coastal flood warning as Hurricane Erin starts moving up the East Coast, according to the National Weather Service.
The warning will start at 5 p.m. Aug. 20 and run through 2 a.m. Aug. 23. The combination of Erin, a Category 2 hurricane, and high tides will lead to 1 to 2 feet of inundation above ground level in low-lying areas near shorelines and tidal waterways in inland Sussex County.
People should expect widespread roadway flooding in coastal and bayside communities and along inland tidal waterways. Many roads may become impassable. Some damage to vulnerable structures may start to occur.

What does a coastal flood warning mean?
A coastal flood warning means that moderate or major tidal flooding is occurring or imminent. Be prepared for rising water levels and take appropriate action to protect life and property.
Driver are reminded to not drive your vehicle through flood waters. The water may be deeper than you think it is. You will be putting yourself in danger and your vehicle may be damaged, leading to costly repairs.
What causes high tide?
According to the National Oceanic and Atmospheric Administration, high tides and low tides are caused by the moon. The moon's gravitational pull generates tidal force. The tidal force causes Earth — and its water — to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
