Freddy Drennan

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.
