See the details on all the harbors and locations where NOAA is predicting possible and likely coastal flooding this month: The Northeast, Mid-Atlantic, Southeast, Gulf Coast, West Coast, and Hawaii.
About these Predictions: “These flooding likelihoods are derived from a probabilistic model that incorporates tide predictions, sea level rise trends, and seasonal changes in coastal sea level to predict the potential that a higher than normal high tide may exceed established National Ocean Service flood thresholds. During these periods, high tide flooding may occur in flood-prone areas.” NOAA
