immediate shorelines and in low-lying spots, or in areas
farther inland near where higher surge waters move ashore.
– Sections of near-shore roads and parking lots become
overspread with surge water. Driving conditions dangerous
in places where surge water covers the road.
– Moderate beach erosion. Heavy surf also breaching dunes,
mainly in usually vulnerable locations. Strong rip currents.

especially in usually vulnerable spots. Small streams,
creeks, canals, and ditches overflow.
– Flood waters can enter some structures or weaken
foundations. Several places may experience expanded areas
of rapid inundation at underpasses, low-lying spots, and
poor drainage areas. Some streets and parking lots take on
moving water as storm drains and retention ponds overflow.
