Freezing temperatures were expected Saturday (Jan. 13) to descend on southeast Louisiana overnight. The low south of Lake Pontchartrain will be at 28 degrees around midnight, and on the North Shore at 23 degrees by Sunday at 4 a.m., the National Weather Service predicted.
All parishes north of the Interstate 10 corridor will be under a hard freeze warning from 6 p.m. until Monday at 8 a.m. A regular freeze warning will be in effect south of I-10.

Water pipes at temperatures this low can freeze and burst, the Weather Service says. Plants, too, are at risk of significant damage.
“At this time, Sunday morning will be our coldest morning over the weekend,” the Weather Service said in a Saturday morning advisory.
Freezing conditions also are expected Sunday night into Monday morning before warmer temperatures arrive.
The weekend cold spell also follows a four-day string of overnight freezing conditions last week.
