The Jersey Shore should prepare for at least a few rounds of tidal inundation through Monday evening.
Astronomical high tides coupled with a strong onshore flow will likely spur minor tidal flooding through early Sunday afternoon and widespread moderate tidal flooding during the Sunday evening high tide.
The Sunday risk has prompted the National Weather Service to issue a coastal flood warning. A coastal flood watch is in effect for Monday morning. Residual minor flooding might occur during the Monday night high tide cycle.
“With four or five consecutive high tide cycles of coastal flooding, there is an increasing concern for prolonged back bay flooding,” according to the bulletin. “Water will have little chance to drain out of back bays in between the high tide cycles, so flooding issues could be exacerbated with subsequent high tide cycles.”
High tide occurs between 7:00 p.m. and 9:00 p.m. Sunday and 7:00 a.m. and 9:00 a.m. Monday.
Widespread roadway flooding is likely, causing some road closures, and some damage to vulnerable structures is possible, according to the bulletin. Heavy rainfall Sunday will also exacerbate any tidal flooding.
Motorists should not drive through flooded areas.
