Freeze Warnings Posted for Portions of Louisiana Tonight

In southern Louisiana, the freeze warning covers the parishes of Allen, Vernon, Evangeline and St. Landry. Residents in these communities can expect low temperatures of up to 30 degrees overnight on Wednesday morning. Freezing temperatures are expected to persist from 4am to 9am on Wednesday morning.

While this is not a severe freeze in itself, it will be cold enough that unprotected and unpackaged exposed water pipes can freeze or rupture. If you have an irrigation system, you should consult your owner’s manual for the precautions you need to take. Some systems suggest a slow drip, while others suggest you drain the water from them.

Plant owners and gardeners will face the greatest threat from these cold weather episodes. Temperatures are expected to be cold enough to damage some tender vegetation as well as tropical plants or plants that thrive in warm climates. If you want to save these plants, consider bringing them indoors or at least providing them with cover during the night.

In the meantime, it will be cold here for the communities south of the warning area as well. Humidity will also be way below. This means an increased risk of fire. That, coupled with gusty north winds, should be reason enough not to light fires outside, even in a fire pit. The risk of fire is increased.

Communities along I-10 namely Jeff Davis, Acadia, Calcasieu, Lafayette, St. Martin and others may experience patchy frosts in the morning. But forecasters suggest temperatures should remain above freezing in this part of the state, although Thursday morning’s freeze warning could be extended to several more communities.

The Old Farmer’s Almanac states that the average date for a first frost in Lafayette is usually no earlier than late November. According to OFA, November 26 is the average first date for a fall frost along I-10.

However, the same article suggests that even a light frost, which we’re likely to see across much of Acadiana tonight and tomorrow night, will be more than enough to kill or damage tropical or tender vegetation. When it gets a few degrees cooler, almost all of the vegetation in South Louisiana’s yards and gardens will feel the strain.
