Icy conditions forecast in Louisiana
A winter weather advisory for all of southeast Texas and central Louisiana, and most of southwest and south central Louisiana has been issued by the National Weather Service in Lake Charles.
The only locations not in the advisory are Cameron, Vermilion, Iberia, lower St. Martin, and St. Mary parishes, Roger Erickson, warning coordination meteorologist, said.
The advisory is in effect from 3 a.m. Tuesday through noon Tuesday, and could be extended if conditions war-rant it, Erickson stated in an email.
For east Texas and central Louisiana, freezing rain and/or sleet will begin after midnight tonight, and continue through midday Tuesday, he stated. Total ice accumulations will be less than 0.10 inch, he stated.
The main impacts from this ice will be to the elevated roads and bridges, which could become extremely haz-ardous Tuesday morning, he stated.
For southeast Texas and southwest and south central Louisiana, rain will switch to freezing rain around 3 a.m. Tuesday, and continue through midday Tuesday, he stated. Total ice accumulations will be around 0.10 inch, he stated. The main impacts from this ice will be to the elevated roads and bridges, which could become extremely hazardous Tuesday morning.
The main forecast question is when the freezing rain will switch back to just rain. This will be dependent on temperatures rising above freezing (32 F). This is expected to occur by noon Tuesday, so any precipitation left in the afternoon should switch to rain, he stated. However, he added that forecaster confidence is low on this exact timing.
Tuesday evening will only have a 20 percent chance for light rain. By Wednesday morning, temperatures will be 32 F or below along and north of the I-10 corridor, so if there are any wet bridges, they could re-freeze early Wednesday morning, he stated.
