In Estonia, a 20-kilometre ice road has been opened due to extremely low temperatures, allowing citizens to drive between the islands of Saaremaa and Hiiumaa. The road was created after locals began using the frozen sea, prompting authorities to ensure safety measures. The cold snap is linked to atmospheric changes affecting the polar vortex, resulting in persistent cold air in Northern Europe. The ice road is monitored for safety, with strict regulations for vehicles using it.
