Annoying minor floods are increasing on US coasts

By

WASHINGTON (AP) — A new federal report says that along much of America's coasts, the type of flooding that is more annoying than dangerous has jumped more than fivefold in the last 50 years.

Scientists blame rising seas, saying this is one of the ways global warming is changing everyday lives.

The National Oceanic and Atmospheric Administration studied nuisance flooding, where no one is hurt but people have to deal with flooded roads and buildings.

Oceanographer William Sweet looked at 25 coastal sites. Fifty years ago they averaged about 2.5 days of minor flooding a year. Now those places average about 14 days a year.

Annapolis, Maryland, topped the list. From 1957 to 1963 it averaged 3.6 minor flood days a year; now it averages more than 39 a year.
