Some roads and low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding. * HUDSON RIVER IMPACTS...Minor flooding of the most vulnerable locations near the waterfront and shoreline expected from surge up the Hudson River. * SHORELINE IMPACTS...Breaking waves of 3 to 5 ft during the time of high tide will result in beach erosion, wave splashover bulkheads exacerbating flooding along shoreline roads and properties, with minor damage possible to shoreline structures. * ADDITIONAL DETAILS...Heavy rain during the time of high tide may exacerbate flood impacts. This forecast is leaned towards a higher end flood impact scenario, to account for slower trend in cold frontal passage and potential coincidence with heavy rain.
