A federal disaster has been declared in parts of south central Louisiana after that storm system that dumped 20 inches of rain and caused massive flooding before moving west. FEMA, the emergency agency, is in Louisiana now, but residents have been launching an emergency response since the weekend.
Civilian volunteers, including a Facebook community of hunters and fishermen, have been throwing their boats on the back of four-wheel drive trucks and rescuing people from completely different towns. It's an extension of a movement founded during Hurricane Katrina known as the "Cajun Navy."
Jared Serigné was home watching the storm footage with his newborn when he remembered a friend who joined the Cajun Navy during Katrina and was inspired to go this time.
Here & Now's Robin Young speaks with Serigné, who has been helping with rescues near Baton Rouge.
Here's a video he took earlier this week (if it doesn't immediately show up, click refresh on your browser):
