Update, 8:30 a.m. Sunday

On Sunday morning, 460 Entergy workers were working to restore power in Tangipahoa Parish, the company said on Twitter. About 14,000 customers were still without power, most of those in Tangipahoa Parish.

Entergy estimated that most customers would have power restored by Sunday afternoon, but areas with "extensive damage" could be in the dark until late Sunday night.

According to its outage map, DEMCO reported that 1,033 households in Livingston Parish were still without power on Sunday morning. The company also reported 171 homes in Ascension, 153 in St. Helena, 89 in East Feliciana and 26 in Tangipahoa were without power. 

Original story

Nearly 100,000 Louisiana households lost power after a rare snowfall blanketed much of the state Friday, taking down tree limbs and power lines.

But energy company spokesmen said they anticipated that power would be restored to almost all of their customers by Saturday evening.

As of 6 p.m. Saturday, Energy had restored services to 52,000 of its roughly 72,300 customers who had lost power at some point. But about 20,000 remained in the dark. The largest number still without power were in Tangipahoa Parish.

About 350 Entergy workers from Louisiana, Texas and Arkansas were working to restore power to the remaining homes Saturday evening, and additional workers were on their way to help out, Entergy spokesman Mike Burns said.

Late Saturday afternoon, DEMCO spokesman David Latona said the largest number of that utility company's outages were still in Livingston Parish. But, he said, the number was down from 8,800 homes without power to 3,000 homes.

Another 723 households in St. Helena Parish, fewer than 700 in Ascension Parish, 200 in East Feliciana Parish and 185 in Tangipahoa Parish were also without power late afternoon Saturday, Latona said.

Latona said households serviced by DEMCO that are still out should regain power by Saturday night.

"Our guys are making great progress," Latona said. "But you know, details lie in what actually happens in the field ... there may be some stragglers left by tomorrow."

As crews works to restore power, Latona said, they are seeing some infrastructure damage, although not nearly as much as that typically caused by tornadoes or hurricanes.

Most of the outages were caused by tree limbs weighed down by the snow touching or falling into power lines, Latona said.

Warmer temperatures and the re-opening of frozen bridges and roads allowed crews to move forward with repairs, Latona said.

Entergy estimates power will be restored by Saturday to homes in the Baton Rouge area, Madisonville, the Hammond city limits, Roseland, and the city limits of Albany and Springfield.

Entergy estimates the power will be restored by late Sunday to homes outside the Hammond city limits, west of the Tangipahoa River along La. 10 and on Dummy Line Road, and outside of Albany and Springfield city limits.
