The threat of the hurricane caused Democratic presidential nominee Michael Dukakis to cancel a rally and two fund-raising events in New Orleans. Governor Buddy Roemer issued for the Louisiana National Guard to be on standby for emergency duty. Officials closed several bridges across southeastern Louisiana and also canceled ferry travel across Lake Ponchartrain. In Pensacola, Florida, the Navy base moved the USS Lexington into the Gulf of Mexico during the hurricane, and also sent more than 100 aircraft to a base in Ohio.
