The stars -- or at least the sun and the moon -- have aligned in just the right way to trigger coastal flooding this weekend from New Jersey to Massachusetts, including New York Harbor.

There are no nor’easters, hurricanes or other severe weather bearing down on the U.S. East Coast, but tides may be pulled a foot (30 centimeters) above normal in many places late Friday and early Saturday, sending the Atlantic onto roads and into vulnerable basements. The highest tides happen when the Earth, moon and sun line up and the gravitational pull on the oceans is at its peak.
