Mount Holly, New Jersey – Minor tidal flooding is expected Monday morning across portions of coastal New Jersey and Delaware, prompting a Coastal Flood Advisory from the National Weather Service.
According to the National Weather Service in Mount Holly, tidal inundation of up to one foot above ground level is forecast in low-lying areas near shorelines and tidal waterways. The advisory is in effect from 7 a.m. to 1 p.m. EST Monday, coinciding with the late-morning high tide cycle.
The advisory covers Ocean, Atlantic, Coastal Atlantic, Coastal Ocean, and southeastern Burlington counties in New Jersey, as well as Cape May and Atlantic Coastal Cape May. In Delaware, Inland Sussex County and the Delaware Beaches are included.
At this flooding level, water typically begins to impact the most vulnerable roads in coastal and bayside communities, along with areas along inland tidal waterways. Some partial or full road closures are possible, particularly on roads that routinely flood during high tide events.
Forecasters also warn that ice from back bays may be pushed onshore during peak tides. As temperatures remain cold, floodwaters may freeze on road surfaces, increasing the risk of hazardous travel conditions even after water levels recede.
Tide forecasts indicate minor flood thresholds will be reached at several locations, including Atlantic City, Barnegat Bay at Barnegat Light, Delaware Bay at Lewes, Great Egg Harbor Bay at Ocean City, and Cape May Harbor. While flooding is expected to be limited in duration, impacts may occur rapidly around the time of high tide.
Residents and visitors in flood-prone areas are urged not to park vehicles in locations susceptible to tidal flooding and to avoid driving through floodwaters, which may be deeper than they appear and could cause vehicle damage or personal injury.
Commuters, service workers, and students traveling Monday morning should allow extra time and remain alert for temporary road closures. Additional water level and tide information is available through the National Water Prediction Service.
