Winds from Tropical Storm Isaac overturned a kayaker who was paddling to his truck, and St. Tammany Parish sheriff's deputies had to rescue the man and his dog.
Sheriff's spokesman George Bonnett Jr. says the man had parked his truck along Highway 90 in the Slidell area, and was paddling from his home to the truck with his dog Wednesday morning when the accident prompted a call to 911.
Bonnett says Marine Division deputies tied themselves to their vehicles with long ropes, then swam to the rescue.
In St. John the Baptist Parish about 25 miles from New Orleans, at least 1,500 people were forced from their homes by floodwaters and thousands should evacuate, according to the governor's office.
Rising water closed off all main thoroughfares into the parish, and in many areas, water lapped up against houses and left cars stranded. F
Floodwaters rose to waist-high in some LaPlace neighborhoods, and the Louisiana National Guard was working with sheriff's deputies to rescue people stranded in their homes and surprised by the flooding.
