El Niño, rising sea spur record 'clear-sky' flooding in 7 cities

El Niño and rising sea levels linked to global warming spurred a record number of days of "nuisance flooding" last year in seven coastal U.S. cities, according to a federal report...

Wilmington, N.C., recorded an all-time high of 90 days, or one-quarter of the year, partly underwater from the "clear-sky" flooding, which isn't caused by heavy rain from a storm

Nuisance flooding leads to road closures, overwhelmed storm drains and damaged property. It occurs with high tides in many locations due mainly to climate-related sea-level rise
