Areas to the west and north of Baton Rouge should expect freezing rain overnight Monday, which could make travel in the early morning hours of Tuesday tricky.
Baton Rouge itself will stay well above freezing, but areas including New Roads, St. Francisville and Clinton will see up to a tenth of an inch of ice accumulation, according to the National Weather Service.
A freezing rain advisory has been issued starting at 9 p.m. Monday evening until 9 a.m. Tuesday morning for Pointe Coupee, West Feliciana and East Feliciana parishes.
Ground temperatures area still pretty warm, so it’s unlikely there will be much accumulation on roads themselves, said Phil Grigsby, meteorologist with the National Weather Service.
However, bridges and overpasses cool much faster and there could be accumulation there as well as some glazing of ice on trees and power lines. There won’t be enough ice to cause concerns about power outages or downed trees, he said.
“Impacts on the bridges will be the most important thing,” he said.
Temperatures are expected to get above freezing Tuesday morning so any ice accumulation should melt fairly quickly.
To the west of Baton Rouge, freezing rain advisories have been issued for numerous parishes mainly along and north of the Interstate 10 corridor.
A freezing rain advisory is in effect from 6 p.m. Monday until noon Tuesday for much of central and southwest Louisiana, including Lake Charles, Crowley, Opelousas, Krotz Springs and Eunice.
