NEW ORLEANS (AP) — The National Weather Service calls an overnight freeze warning across south Mississippi and in four Louisiana parishes.

Louisiana strawberry farmers are putting covers over plants to protect them.

Meteorologists say people should expect four or five hours of temperatures that can kill crops and other sensitive vegetation. Animals should also get extra protection.

The freeze was predicted to start after midnight and continue until an hour or two after sunrise.

In Mississippi, the warning covers Wilkinson to Walthall counties and Pearl River to George counties south — except for places right on the coast — and north into Perry, Green and Wayne counties.

In Louisiana, it affects St. Helena, Washington, St. Tammany, and Tangipahoa parishes.
