Updated November 21, 2024:
Due to the passage of the Caetano depression over France, Météo France forecasts snow in the plains on an axis going from North Brittany/Normandy to the Grand-Est, sometimes heavy snow over the Alps and an episode of winds strong from the Atlantic coasts to the Northern Alps then back to Corsica.
Météo France has placed the Côte-d’Or on Orange alert for snow and ice, from this Thursday, November 21, 2024, 11 a.m., until this Friday, November 22, 2024, noon. A yellow alert will ensue until at least midnight Friday.
All departments of Burgundy-Franche-Comté will be affected to varying degrees by this vigilance against snow and ice. Saône-et-Loire, Jura and Doubs will also experience yellow vigilance in strong winds.
In this context, the Côte-d’Or prefecture recalled the precautions to be taken (read the press release).
Inforoute 21 press release of November 21, 2024:

Current situation
New developments: confirmation of forecasts.
General situation: an active disturbance linked to the CAETANO depression extends over Burgundy-Franche-Comté as well as the south of the Grand-Est. This disturbance gives snowfall (locally sustained) at low altitude in the departments concerned.
Notable observations: snowfall occurs in Burgundy-Franche-Comté, Champagne, Vosges and Haut-Rhin. Up to 3 to 5 cm of snow has fallen on Burgundy and the Langres plateau in the Vosges department since mid-to-late morning on Thursday.
Predictability and uncertainties
The uncertainties lie in the southern extension of the orange snow-ice warning and depend on the trajectory of this depression. This is why other departments may be placed on orange alert during future vigilance updates.
Snow Ice
Qualification
Early snowfall for the regions concerned and sufficiently notable to make traffic conditions difficult.
Expected development
The snowy episode continues until the first part of the night in all departments on alert. It is then confined to Franche-Comté and Haut-Rhin in the middle of the night from Thursday to Friday, before evacuating towards Switzerland and the Alps at the end of the night.
In all the departments concerned, 5 to 10 cm of snow is generally expected.
Locally, accumulations could rise up to 15, locally 20 cm in Yonne, on the Côte d’Or plateaus, in Haute-Saône and in the Belfort/Montbéliard/southern Haut-Rhin sector.
The snowfall fades in the second half of the night from Thursday to Friday, shifting towards Switzerland and the Alps.
Be careful, a widespread refreeze occurs in the second part of the night, hence an extension of the orange alert until Friday midday.
For information after the exit from orange vigilance in the middle of the day on Friday the departments remain on yellow vigilance for the risk of snow/ice. In fact, light snow showers are circulating during the day on Friday. The forecast snowfall accumulations remain low and heterogeneous.
