The Louisiana National Guard sent high-water trucks to Crowley and Marksville for evacuations, and says units are on standby statewide.
Staff Sgt. Denis Ricou says the 225th Engineer Brigade in Marksville and the 256th Infantry Brigade Combat Team in Crowley each sent a truck and two soldiers.
He says the guard also brought about 50,000 empty sandbags Thursday to Livingston Parish.
Police say a 34-year-old Crowley woman they arrested tried to convince investigators that her estranged boyfriend was sending her threatening text messages.
The Advertiser reports Trudy Miller was arrested Tuesday on one count of false swearing for violation of health or safety, a felony charge.
Crowley Chief of Police K.P. Gibson says Miller was believed to be the victim of stalking about five weeks ago when she filed her first complaint.
