NEW ORLEANS (AP) — As rain followed rain in south Louisiana, the president of the Louisiana Crawfish Farmers Association saw a good chunk of his crop swim over the levees around his ponds while fish swam in to feast on those remaining.

David Savoy of Church Point says rains since last week have overtopped the levees in about 35 percent of his 1,700 acres of ponds. But he says those are his most low-lying ponds, which also tend to be the most productive.

The National Weather Service has called a flash flood watch in northeast Louisiana and northwest Mississippi.
 with a chance of freezing rain overnight in some areas.

Farther south, rain is in the forecast at least until Wednesday in the southwest and possibly into Thursday in southeast Louisiana and south Mississippi.
