Black ice may be on roads in central Texas

8 p.m. update: The Texas Department of Transportation is reporting heavy congestion and traffic posts along Interstate 35 in both directions as snow continues to fall in the Austin metropolitan area.

In the last 30 minutes, jobs have been reported in Austin near Aquarena Springs, Parmer Lane and Rundberg Lane, according to TxDOT. The traffic posts have also been reported in Buda, San Marcos and Jarrell.

A warning about the winter weather is still valid until midnight. Drivers must expect slippery roads and limited visibility.

7:20 p.m. update: The National Weather Service has issued a winter weather advisory until midnight for central Texas and Hill Country.

Meteorologists say snow accumulations of up to an inch are expected in the area, which could cause travel difficulties. Up to 1.2 inches or snow has been reported at the Austin-Bergstrom International Airport.

Drivers must expect slippery roads and limited visibility, the weather service said.

The icy weather has led Austin Community College to cancel all of its classes for the rest of Thursday afternoon, authorities said. The ACC will provide updates on any other cancellations or delays through social networks, officials said.

In Hays County, classes in the Wimberley school district will have a late start on Friday due to weather. Classes will begin at 10 a.m., the school district said.

5:50 p.m. update: The snow moving west from Hill Country has now reached Austin.

What began as a mixture of snow and rain has been replaced by light and heavy snow gusts throughout the Austin metropolitan area.

The weather radar shows snow falling from New Braunfels to Williamson County, and extends westward along Interstate 10.

Meteorologists expect some snow to accumulate in the band from Uvalde to Boerne and Austin. The band is expected to move slowly to the south and east, with smaller sections separating to the northeast, they said.

4:30 p.m. update : The National Weather Service has received reports of snow flurries in the Austin area.

Accumulations are not expected since the precipitation rates are too low and the soil temperature remains above the freezing point, says the meteorological service.

Meanwhile, Austin Water offers these tips to help homeowners protect their properties and prevent the loss of water from frozen or broken water pipes. The utility of the city recommends:

Before the freezing occurs. . .

• Wrap all exposed pipes outdoors or in unheated areas of the house.

• Remove garden hoses from outdoor faucets.

• Cover the vents around the base of your home.

• Know where you cut -off valve is located and how to use it. The valve is located next to the water meter housing under a 6-inch metal lid.

When it is below zero. . .

• Drip outside faucets at a rate of 5 drops per minute. But the utility says that this is not necessary unless temperatures are expected to be 28 degrees or less for at least 4 hours.

• Open the cabinet doors under the sinks adjacent to the exterior walls.

• In unheated garages, close the washing machine.

• In climates held at low temperature, let water drip slowly from inside the keys.

• Take extra precautions to protect pipes that have been frozen in the past.

Austin Water has a 24-hour emergency hotline at 512-972-1000; and more information is available at austinwater.org.

3:15 p.m. update : Sub-zero temperatures are expected throughout central Texas on Thursday night, warns the National Weather Service, and drivers must take into account the dangerous black ice that forms the roads.

Meteorologists say roads exposed to humid weather, such as bridges, overpasses and service roads, may be vulnerable to black ice.

The Hill Country and areas along Interstate 35 to New Braunfels may experience a hard freeze tonight, the weather service says.

Temperatures should fall below freezing or just after midnight, first in Hill Country, and later through the I-35 corridor, meteorologists say. Some bursts of snow may fall during the night, but only very south of the Austin metropolitan area, south of I-10 and east of I-37.

During a heavy freeze, forecasters say that exposed pipes could break. Residents must bring sensitive plants and pets indoors.

Hyperthermia is also a risk for older residents or younger children who may be exposed to extremely cold temperatures for an extended period of time, says the weather service.

: The persistence of cold temperatures on Tuesday's cold front and the entry of moisture into central Texas from the Pacific through Mexico could cause a "winter mix" of precipitation in much of the region, warns the National Metereological Service.

This combination of rain and snow is expected to fall largely in the northern and western parts of the region, but the National Weather Service included Austin in its weather warning on Thursday morning.

But the weather service noticed that the ground – still hot from the last weeks of heat above normal – means that falling snow should melt on contact, said Nick Hampshire, a weather service meteorologist. Accumulations are not expected.

"We should have a pretty good freeze tonight," said Hampshire. "Apart from that, the rain will slowly clear from north to south."

High temperatures in Austin should reach 40 degrees on Thursday afternoon. There will be cold during the night, with the minimum expected to submerge in the top 20.

However, the weather should improve noticeably, starting on Friday, when the sun is expected to resurface. Saturdays and Sundays are expected to return to 60, while minimums should remain at 30.

"This weekend looks very good," said Hampshire.

These are the highlights of the extended weather service forecast:

  • Thursday: & # 39; Winter mix & # 39; possible this morning since the high temperatures should reach 48 degrees in the city, before falling to 29 during the night while the clouds and rain outside.
  • Friday: Sunny, with a maximum of 55 degrees and a minimum of 36.
  • Saturday: More sun, with a maximum of 66 degrees with a minimum of 36.
  • Sunday: Continuous sun, with a maximum of 63 degrees and a minimum of 38.
  • Monday: High of 69 degrees with a minimum of 42.
