A late and uneven freeze-up on the Anadyr Estuary has delayed the seasonal ice-road crossings linking Anadyr with the airport area, as ice thickness and cracks are still unsafe for heavy equipment.

Fast ice has formed in the Anadyr Estuary near Anadyr, but a warm cyclone brought milder air and stronger winds, slowing ice growth and reopening a polynya in the central estuary. Hydrologists say the ice is still thin and unsafe, and thickness measurements will not start until at least January 10.

Thick, continuous ice up to 30–40 cm hindered docking of the cargo ship FESCO Moneron at the Port of Anadyr, with successful mooring only on a second attempt. Ice navigation has been declared since October 18, restricting entry to vessels of at least Ice 2 class.
