* WHAT. Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways. * WHERE. In Delaware, New Castle. In New Jersey, Salem. * WHEN. From 11 PM this evening to 3 AM EDT Friday. * IMPACTS. At this level, flooding begins on the most vulnerable roads along tidal waterways. Some partial or full road closures are possible. * ADDITIONAL DETAILS. Another round of widespread minor coastal flooding is forecast for 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.

* WHAT. For the Coastal Flood Advisory, up to one foot of inundation above ground level expected 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, from 8 PM this evening to 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.
