Memorial Day Beachgoers Beware: High Bacteria Levels and Sewage Contamination Close Several US Beaches.

Beachgoers in several US states are being warned of heavy rain, windy conditions and unhealthy bacterial levels this Memorial Day weekend. Some beaches are likely to be plagued by cloudy weather or gross mats of seaweed. Southern Californians looking forward to a beach weekend might be in for a disappointment due to high bacteria levels and blue jellyfish. Southeast Florida beaches have been blanketed with "blobs" of sargassum seaweed, which can produce a foul smell and even irritate the eyes, nose and throat. The National Hurricane Center is monitoring a storm system off the coast of South Carolina this weekend and warned it will cause dangerous riptides and gusty winds along the southeastern U.S. coastline.
