Here’s how MDOT keeps ice and snow off the roads
Don’t get your hopes up for a full-blown snowpocalypse like the Coast experienced in January 2014.
Weather forecasters say the three coastal counties may have some snow mixed in with rain on Tuesday, but the biggest challenge will be frigid wind chills.
“As a strong cold front on Monday comes through the Mississippi Coast comes through mid-Tuesday morning, there may be a few snow flurries mixed in with the rainfall,” said meteorologist Mike Efferson of the National Weather Service in Slidell.
Hancock, Harrison and Jackson counties may each have some frozen mixture after 9 a.m., Efferson said.
“With temperatures in the 40s, precipitation will dry up pretty quickly,” he said.
The northern counties of Pearl River, Stone and George are more likely to see snow flurries. Rain and snow is possible before 9 a.m., then a slight chance of snow until noon.
The greatest chance of accumulation is in the southwest counties of Wilkinson and Walthall, the weather service said. There isn’t expected to be any accumulation on the ground in the lower six counties, and no travel impacts are expected there.
Central Mississippi and the cities of Vickburg, Jackson and Columbus could see 1 to 3 inches of snow, the weather service said.
But the Coast can expect a frigid wind chill dipping into the 20s from daybreak Tuesday through at least lunchtime, and again Tuesday night, Efferson said.
A hard freeze is expected Tuesday night with actual temperatures in the 20s for most of the area through Wednesday morning. The weather service said freeze watches and warnings are likely to be issued Tuesday afternoon.
The following Coast school districts have canceled class Tuesday:
- George County
- Pearl River Community College
- Greene County
- Jones County
- Southern Miss in Hattiesburg (Long Beach campus will remain open)
- Mississippi Gulf Coast Community College (day classes only, night classes resume as normal)
The Mississippi Department of Transportation is advising motorists to slow down on wet roads, whether it’s snowy or not.
MDOT will be pre-treating roads and bridges north of the Coast with a sodium brine, which lowers the freezing point.
If ice does form on coastal highways, it would be more likely to appear on bridges.
Black ice is not expected in the coastal area, the weather service said.
