Lafayette City-Parish President Joey Durel has signed an emergency declaration for Lafayette Parish, and non-essential government workers have civil leave Wednesday.
The parish is under a hurricane watch and tropical storm warning as Hurricane Isaac approaches the northern Gulf Coast. In Lafayette Parish, winds were expected to gust up to 30 or 40 miles an hour starting late Tuesday afternoon, with gusts of 50 to 60 mph expected for most of Wednesday.
Officials say Lafayette residents should drive only when necessary after 6 p.m. Tuesday.
Slidell police say Mayor Freddy Drennan has called a dusk-to-dawn curfew for Hurricane Isaac.
Assistant Chief Kevin Foltz says it probably will be lifted at daylight Thursday.
It won't apply to emergency workers. Foltz says the curfew is designed to keep the roads clear for emergency crews, to protect city residents and to make it easier for police to protect their property.
The Coast Guard is searching the Gulf of Mexico near the Florida-Alabama state line for a man who failed to return home from a water-scooter trip as then-Tropical Storm Isaac was approaching the coast.
Chief Petty Officer Bobby Nash says the search began after the man's wife called the Pensacola station about 8:45 p.m. Monday. It resumed at dawn Tuesday.
He didn't have any details about the man.
He says a fixed-wing aircraft and a helicopter started the search, but the plane had to return — and winds were likely to get too rough for the helicopter.
Two shelters have opened in St. Tammany Parish as Hurricane Isaac approaches.
Officials of the St. Tammany Parish School Board and the Red Cross said the shelters are at William Pitcher Junior High School, 415 S. Jefferson Ave. in Covington and at Creekside Junior High School, 65434 Louisiana Highway 41, Pearl River.
People going to the shelters are asked to bring food, medicine, bedding and activities for children.
