The yellow warning applies to all of Latvian territory. 'Yellow' is the second level of four levels of warning, and means 'potentially dangerous' conditions exist as a result of temperatures that are likely to hover a couple of degrees below freezing throughout Tuesday.
According to Latvian State Roads (LVC), more than 100 technical teams are currently out and about on snowplow and gritting duty.
It's worth remembering that starting December 1, all vehicles in Latvia must be equipped with winter tires until March 1 for the winter season and require at least 4 millimeters of tread.
More information (in Latvian) about the legal requirements is available at the CSDD's information on winter tires section of its website.

Pedestrians will also need to take extra care with Rīga City Council urging walkers to be aware that layers of ice could form quickly on sidewalks with freezing rain expected Tuesday afternoon.
"Residents should expect that sidewalks and roadways will be slippery during this weather. From this year, changes in the territory maintenance rules in Rīga allow the use of clean salt for sprinkling the sidewalks again, so that it is safer for residents to move on the sidewalks," the council said.
"We would like to remind you that this winter in the historical center of Riga and its protective zone (RVC) the maintenance of sidewalks is provided by the municipality. In the rest of the city, the maintenance of the sidewalks must be provided by the owners of the adjoining areas, as before. To make sure which streets are adjacent to the sidewalks in the RVC zone, we invite you to look at the map on the municipality's website riga.lv."
Residents whose properties abut sidewalks can receive 50 kg of free sand for sprinkling sidewalks. This also applies to residents whose properties are located in the RVC. The Riga City Council's Territorial Improvement Department has currently provided 1,200 tons of sprinkler material.
