- Snow and ice will develop Monday night in Texas and Lousiana before spreading eastward across the South.
- Forecast snow and ice totals are uncertain, especially when it comes to the nothern extent of the wintry weather.
- Regardless, travel conditions are likely to be hazardous from around Interstate 10 to areas near and south of Interstate 20.
Winter Storm Enzo will bring a stripe of snow and ice to the South early this week, creating dangerous travel conditions including in areas near the Gulf Coast where winter weather is rare.

Winter Storm Alerts Posted
The National Weather Service has posted winter storm alerts across the South from central and eastern Texas to parts of Georgia. Cities in those alerts include Houston, New Orleans and portions of the Atlanta metro area.
These alerts mean that snow, ice and wind could combine to make conditions dangerous early this week. Roads may become covered in snow and/or ice and power outages are possible.

Here’s a day-by-day look at the upcoming winter storm and some additional caveats to the forecast:
Monday Night’s Forecast
- The first collision of cold and moisture will likely occur over Texas and Louisiana late Monday.
- It is likely that there will be a zone of snow, sleet and freezing rain, especially near and south of Interstate 20 to the Gulf Coast.
- Many bigger Texas cities will see the threat of snow and/or ice, including Houston, San Antonio, Austin and Corpus Christi.
- The northward extent of this wintry weather is the most uncertain part of the forecast, so expect changes.
- There is some ice threat for parts of South Texas from Galveston to the Rio Grande Valley.
(While it is too soon to pinpoint precisely who will see what precipitation type, the green shadings depict where rain is expected. Areas that are shaded blue are expected to see snow. Purple-shaded locations may see either rain or snow. Areas in pink are expected to see sleet or freezing rain (ice).)
Tuesday’s Forecast
- Moderate to major impacts are possible from eastern Texas to southern Mississippi, including Houston and New Orleans. Closures, dangerous travel, power and other infrastructure disruptions are possible.
- Snow and ice will spread farther east along the Gulf Coast into parts of Alabama and Georgia, the Florida Panhandle, and the Carolinas through Tuesday night.
- For now, precipitation will fall as snow along and north of Interstate 10 and as a wintry mix along and south of Interstate 10.
- Precipitation in the Florida panhandle is expected to begin Tuesday as plain rain. During the evening hours, this rain may become freezing rain or sleet as temperatures cool.
- Wind gusts over 30 mph are possible near the Gulf Coast. This could blow snow around and lead to broken branches.
- The northern and eastern extent of this storm’s moisture, and thus snow and ice, is highly uncertain. This includes the Atlanta metro area, where hazardous travel is possible Tuesday depending on how far north this storm’s snowfall spreads toward Interstate 20.
(While it is too soon to pinpoint precisely who will see what precipitation type, the green shadings depict where rain is expected. Areas that are shaded blue are expected to see snow. Purple-shaded locations may see either rain or snow. Areas in pink are expected to see sleet or freezing rain (ice).)
Much of this storm will be over with by Wednesday morning, but some snow and ice might linger in northeast Florida and the coastal Carolinas.
Snowfall Forecast
Below is a look at the latest snowfall forecast, but keep in mind changes are likely given lingering uncertainties in the forecast.
- At least a few inches of snow will pile up from southeast Texas into Louisiana, southern Mississippi and southern Alabama. Where bands of heavier snowfall rates develop we could see higher totals of up to a half-foot.
- Accumulating snow is also possible in parts of Georgia and eastern Carolinas.
- As mentioned earlier, the northward and eastern extent of any accumulations is highly uncertain, including around Atlanta, the rest of Georgia and the Carolinas. However, even light amounts could create hazardous travel conditions.
- There is also a zone from the Florida panhandle to coastal South Carolina, and also southern Texas, that may pick up enough ice to cause tree branches to bend and roads to get slick.
Wintry Mess Via Common Tricky Setup
The configuration for this snow and ice threat is common as we slide through late January and into the second half of the winter.
Widespread arctic air is taking over much of the central and eastern U.S., including well into the Deep South. This source of fresh, cold air is the first ingredient needed to get snow and ice along the Gulf Coast.

At the same time, a weak wave of low pressure over the Gulf of Mexico will help lift moisture northward into the region, resulting in snow and ice.
