I lost my family," said Edrick Alexander, the father of the toddler.Louisiana Governor John Bel Edwards said the Weather Service had issued a "high risk" advisory for central and northern Louisiana, warning residents to be vigilant of the threat of severe weather.In addition to tornado threats, thunderstorms were bringing hurricane-force, straight-line winds and large hail to the region, the governor said.
