Some parts of St. Landry Parish already are flooding as water from the flood in Avoyelles Parish travels south. But the worst of the water, St. Landry Parish President Jessie Bellard said Tuesday, is expected to start arriving in about 5-6 days. Tropical Storm Arthur last week dumped as much as 30 inches of rain on some parts of Louisiana, including parts of Avoyelles Parish, flooding homes. That water, which is not contained within rivers and canals, is traveling south toward St. Landry Parish.
