Is the abnormal rise of water generated by a storm. This surge is in addition to any normal tide range that occurs daily. The combination of normal tide and storm surge is known as Storm Tide. Hurricane Camille in August 1969 produced a 24-foot storm tide along the Mississippi Coast. Hurricane Katrina in 2005 produced a 27-foot storm tide also along the Mississippi Coast.

Hurricane Watch – a hurricane watch is issued for a stretch of coastline when hurricane conditions are POSSIBLE within the next 48 hours.
