* WHAT. For the Coastal Flood Advisory, up to 1 to 2 feet of inundation above ground level expected in low-lying areas near shorelines and tidal waterways. For the Beach Hazards Statement, dangerous rip currents, large breaking waves expected, and strong longshore currents in the surf zone. * WHERE. Northern Outer Banks and Hatteras Island. * WHEN. For the Coastal Flood Advisory, from 6 AM Thursday to 11 AM EDT Saturday. For the Beach Hazards Statement, from 8 AM EDT Thursday through Thursday evening. * IMPACTS. Up to 1 to 2 feet of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways resulting in a low threat of property damage. Localized ocean overwash will be possible for vulnerable portions of Hatteras Island, especially around time of high tide. Some roads and low lying property including parking lots, parks, lawns, and homes adjacent to the waterfront will experience shallow flooding. Rip currents can sweep even the best swimmers away from shore into deeper water. Dangerous shore break can throw a swimmer or surfer head first into the bottom causing neck and back injuries. Strong longshore currents will create dangerous swimming conditions. * ADDITIONAL DETAILS. The most likely time for strong rip currents to occur is a couple hours either side of low tide, which will occur around 2:00 PM.
