Life threatening, and widespread coastal flooding is expected with significant damage to coastal structures and roadways. Water may enter beachfront structures not elevated on pilings. Nearly all waterfront and coastal access roads will be closed, possibly for an extended period of time. Significant inundation of coastal, bayside, sound-side tributaries and tidal creeks is likely.
