* WHAT...Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways. * WHERE...Inland Sussex and Delaware Beaches. * WHEN...From 8 AM to 3 PM EDT Thursday. * IMPACTS...At this level, flooding begins on the most vulnerable roads in coastal and bayside communities, and along inland tidal waterways. Some partial or full road closures are possible. * ADDITIONAL DETAILS...Additional minor coastal flooding is forecast with the morning high tides into the weekend. Minor coastal flooding may linger on the back bays after the time of high tide.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
