Freeze warnings are still in effect for most of southeast Louisiana Wednesday morning as the region experiences record low temperatures overnight.

The National Weather Service in New Orleans has issued a hard freeze warning for the following areas in the WWL-TV viewing area until 8 a.m. Wednesday: St. Tammany, Tangipahoa, Washington parishes and Hancock and Pearl River counties.

Forecasters say sub-freezing temperatures as low as 24°F are possible in those areas. Freezing temperatures are expected to last up to 10 hours, with a hard freeze duration up to 8 hours for areas inland.

A freeze warning has been issued for areas south of Lake Pontchartrain until 3 p.m.., including Jefferson, Lafourche, Orleans, Plaquemines, St. Bernard, St. Charles, St. James, St. John the Baptist, and Terrebonne parishes.

Temperatures in these areas are expected to dip as low as 28°F. These areas will see freezing conditions for up to five hours on Wednesday.

Freeze conditions will kill crops and sensitive plants as well as damage unprotected outdoor plumbing. Take steps now to protect tender plants from the cold. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly. Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing.
