Storm surge...a dangerous storm tide will raise water levels byas much as 4 to 6 feet above ground level along the immediate coastto the north of where the center has made landfall. The water couldpenetrate inland as far as several miles from the shore with depthgenerally decreasing as the storm tide moves inland. Near thecoast...the surge will be accompanied by large and destructivewaves. The storm tide and waves will gradually diminish onThursday.
