Now that the winter storm has passed, the big story today will be the lingering impacts (ice covered roads) and extremely cold temperatures!
Please, follow along as we break it all down with what to expect today thru the weekend...#lawx #mswx
(1/6)
⚠️ Today: Ice covered roadways from yesterday's snow will continue to impact travel, as temps will struggle to reach above freezing for most areas. Travel is NOT RECOMMENDED but if you must travel, check road conditions and plan accordingly! #lawx #mswx (2/6)
➡️ Outside of icy roads, temperatures are downright FRIGID this morning with many areas in the teens (and yes, even a few single digits!) PLEASE dress accordingly if you go outside for ANY duration. These temperatures are NOT what we are used to!! #lawx #mswx (3/6)
We still have a Winter Storm Warning across all of the area for tonight through Tuesday Evening. Roads will be dangerous, so consider delaying travel tomorrow, if possible. If you do have to travel, use extreme caution.
(2/4)🥶 There now is also an Extreme Cold Warning for the entire area Tuesday night and Wednesday morning for wind chills ranging from 8-15 degrees.
Make sure to protect the 4 P's: people, pets, plants, and pipes!
(3/4)❄️In terms of snowfall, amounts have increased and shifted southward slightly today with widespread amounts of 5-7 inches across the I-10/12 corridor.
Due to the cold temps, even during the day Wednesday, the snow might be slow to melt off, making travel difficult.
A Winter Storm Warning in now in effect for SE Louisiana as well as SW &coastal Mississippi.
Moderate to major impacts are expected & travel should be avoided if at all possible Tuesday & Wednesday as snow will likely not have a chance to melt during the day Wednesday.
(1/4)
Heavy snow is forecast to affect the area, with 4-6" of snow for areas generally north of I-10/12 and 1-3" south of I-10/12, including the New Orleans metro area.
The heaviest snow will fall during the day Tuesday and hazardous travel conditions are expected.
(2/4)
The bulk of the precipitation should fall as snow, but a light glaze of ice (less than one tenth of an inch) is also forecast for areas along and south of the interstate corridor. There is a low chance (10%) of totals approaching one quarter inch for some areas SW of NOLA.
Here's the latest on the upcoming winter storm. Cold weather impacts will be greatest Monday through Thursday, but hazardous travel is also expected Tuesday due to wintry precipitation.
(1/ )
With the cold temperatures and wind chills, a Cold Weather Advisory is in effect for the entire area tomorrow night and then again Monday night through Tuesday. Extreme Cold Watches/Warnings will likely be needed for Tues/Wed.
