Up to 6 inches of snow fell on top of a layer of ice overnight in Central Texas, the National Weather Service said. Temperatures are not expected to get above freezing until Wednesday afternoon.

The winter storm could lead to "major stress on the region's infrastructure as well as cripple travel," the weather service says.

Power is out for hundreds of thousands of people across Central Texas. The state’s grid operator has ordered rolling blackouts because of the high demand for electricity.

"The severe winter weather continues to cause significant issues for many in Central Texas," Hartzell said. "Power outages and other challenges have made it difficult or impossible for many to work or learn, even remotely."

He said UT would continue to monitor the situation and announce a reopening when it was determined to be safe.

7 p.m. update — There are more Austin Energy outages now than at any other time today

5:05 p.m. update — ERCOT is in the process of restoring power to 500,000 households in Texas

The Electric Reliability Council of Texas says it is beginning to restore power to 500,000 homes that have been without electricity during Monday's below freezing temperatures and winter storm.

“It’s also important to remember that severe weather, mainly frigid temperatures, is expected to continue, so we’re not out of the woods," ERCOT President and CEO Bill Magness cautioned.

ERCOT, which manages Texas' electric supply, says it was already contending with frozen wind turbines and limited gas supplies on Sunday when additional sources of power went offline with the worsening weather.

The outages will likely continue through tomorrow, according to the operator. Read more on ERCOT's response from KUT's Claire McInerny.

The city recommends residents gather two gallons per day of potable water for every member of your household for a 72-hour period.

"One way to gather this water is to collect water dripping for your faucets to prevent freezing," the City of Pflugerville said in a tweet. "Please continue to use water wisely, and spread this message to people who do not currently have power or internet access."

The City of Kyle is simply asking residents to suspend all water use until further notice.

3:20 p.m. update — Williamson County first responders ask residents to stay home as calls pile up

Williamson County Emergency Medical Services paramedics are responding to a spike in calls for fall-related injuries due to the weather.

The county reported that EMS responded to 12 calls on Saturday for injuries related to falls. The county received 44 of these calls Sunday.

The county is asking residents to stay inside and avoid slick ground outside to reduce the risk of a fall requiring emergency services.

“Although our paramedics are prepared to respond to all calls, we ask that our residents do their part right now to avoid any potential hazard,” Williamson County EMS Director Mike Knipstein said in a news release. “Preventing a fall by staying indoors allows our field paramedics to continue working around the clock to answer serious and life-threatening emergencies.”

Paramedics are also seeing more calls related to people running low on oxygen. They advise residents to contact their providers and use the minimum amount of oxygen allowed to make their supply last.

Williamson County EMS says the department is fully staffed and working to reach people, but with the uptick in calls, the wait time may be longer than usual.

3 p.m. update — Power outages could last through Tuesday

Nearly 190,000 Austin Energy customers may remain without power through Tuesday as temperatures remain below freezing. General Manager Jackie Sargent called the situation “unprecedented" in a Monday news conference.

Austin Energy says it takes its direction from the Electric Reliability Council of Texas, or ERCOT, which advised rotating outages earlier Monday morning. But Austin Energy can no longer do the rotating outages because it’s already cut off power – or "shed load" – on all available circuits that don’t include some kind of critical needs, like hospitals.

“We’re stuck here until we can get some reprieve from ERCOT,” Sargent said.

A state of disaster proclamation Williamson County Judge Bill Gravell issued Sunday allows for the county to take necessary measures to protect the health of residents and activates aspects of the county’s Emergency Management Plan.

The state of emergency will last for seven days, unless continued or renewed by the Commissioners Court. The county’s Emergency Operations Center will also be active until the “winter weather is no longer a threat.”

“We want to impress on the people of Williamson County the importance of staying home and not getting on the roads as much as possible,” Gravell said in a statement. “By staying home, you can do your part to keep other people safe, including our first responders.”

A travel advisory was issued over the weekend for west and northwest parts of the county. People who must travel are urged to use extreme caution.

The county will be updating its website with any changes and closures throughout the day.

Austin officials are discussing whether to open a mass warming site, such as the Palmer Events Center, Mayor Steve Adler told KUT's Audrey McGlinchy.

Adler said Austin Energy cannot say when power will be restored to homes and that it can't bring everyone back online right now because it could overload the grid. He said officials with Austin Energy are waiting on information from ERCOT this morning.

Council Member Greg Casar told KUT by text that he has been asking Austin Energy for answers as to when power can be restored, but is “not getting info that we need.”

9:13 a.m. update — Austin 311 lines and the city's website are down

As a result of power outages and technical issues, Austin's nonemergency 311 line and its official website are no longer working.

Austin Energy's outage map currently shows almost 196,000 customers without power.

7:40 a.m. update — Austin Energy currently unable to rotate outages, urges customers with power to conserve energy

Austin Energy says its ability to rotate outages among customers has been affected, resulting in thousands of households without power since early this morning. The state's electric load must be reduced to fully restore power across Texas, the electric utility said in a tweet.

"If you have power, please try to help the grid by reducing your energy use, your heating being a high-energy user!" Austin Energy said, recommending customers with power turn down thermostats to 68 degrees or lower.

Other ways you can help conserve energy include unplugging any nonessential lights and appliances and avoiding using large appliances like washing machines and ovens.

While rolling outages are normally short events, the electric utility said, they can be longer if the state's electric grid requires it.

7:01 a.m. update — Capital Metro suspends service

Capital Metro says it has suspended service due to the extreme snow and ice.

"We will continue to monitor road conditions throughout the day, and we will resume service if conditions improve," the public transit agency said in a tweet.

6:13 a.m. update — Thousands will be without power "until conditions improve"

Austin Energy says rotating outages that were expected to last only up to 40 minutes will continue "until conditions improve."

"Conservation is still needed by those who have power — especially as you're waking up this morning," the utility said in a tweet. Customers are urged to use only the amount of electricity needed for heating and safety.

“The situation continues to worsen across TX and here in Austin," General Manager Jackie Sargent said in a tweet. "Austin Energy implemented required outages early Monday morning, doing our part to help stabilize the ERCOT grid. The required outages are more extensive than anyone expected and do not allow us to bring affected customers back online at this time."

More than 178,000 customers are currently without power, according to Austin Energy's outage map.

4:01 a.m. update — More than 150,000 Austin Energy customers are without power

As a result of record energy demand during the winter storm, rolling electricity outages are underway across Texas. Austin Energy's outage map shows more than 157,000 energy customers — about 30% of the total — are currently without power.

What's a rolling outage or blackout? Austin Energy says it's a temporary, controlled interruption of your electrical service lasting 10-40 minutes before moving on to another area. But due to the severe weather and state of the electric grid, some of the outages are lasting longer, the utility warned.

The Electric Reliability Council of Texas, or ERCOT, which manages the state's grid, declared an energy emergency alert level 3 this morning — meaning rotating outages are underway across the state. ERCOT says the outages generally occur in residential neighborhoods and small businesses.

ERCOT has urged Texans throughout the winter weather event to conserve energy as much as possible.

Citing concerns about the impact of the severe winter weather, the City of Austin and Travis County have declared states of disaster for the next several days. Local officials are asking people to stay off of the roads if they can.
