Due to the onshore flow from a coastal storm, tidal flooding is possible along the Hudson River this weekend. Based on the latest forecast, the river may exceed flood stage during high tide on Sunday afternoon and possible Sunday night as well. Minor flooding of lowlands along the river may be possible.
Coastal flooding is defined as saltwater or freshwater inundation along the coast and can be caused by storm surge, onshore winds, high surf, or high astronomical tides. If coastal flooding is expected in your area, follow the advice of your local officials. Do not drive through flooded roads and parking lots of unknown depth...what may look like a puddle could actually be a washed out road.
Here are some key messages regarding the strong coastal low expected to impact the east coast this weekend. Strong winds, coastal flooding, beach erosion and heavy rainfall will all be hazards with this storm system.
