* WHAT...For the Coastal Flood Advisory, up to one foot of inundation above ground level in low-lying areas near shorelines and tidal waterways. For the Coastal Flood Watch, one to two feet of inundation above ground level possible in low-lying areas near shorelines and tidal waterways. * WHERE...In Delaware, Kent. In New Jersey, Cumberland. * WHEN...For the Coastal Flood Advisory, until 2 AM EDT Friday. For the Coastal Flood Watch, from Friday evening through late Friday night. * IMPACTS...At the moderate coastal flood level, widespread roadway flooding occurs in coastal and bayside communities and along inland tidal waterways. Many roads become impassable. Some damage to vulnerable structures may begin to occur. * ADDITIONAL DETAILS...Increasing onshore flow during the day on Friday combined with the higher astronomical tides will increase the potential for moderate coastal flooding with the Friday night high tide. The Friday night high tide is forecast to have the highest water levels and greatest impacts with this stretch of coastal flooding, and high tide water levels will lower over the weekend.

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.
