Widespread snowfall and a sharp drop in temperatures have swept parts of central and western Iran. In Arak, heavy snow on Wednesday, December, 17, 2025, forced the closure of all primary and lower secondary schools for the afternoon shift. A new, moisture-laden weather system entered Chaharmahal and Bakhtiari late Friday, bringing extensive rain and snow across the province through Saturday morning, including the city of Shahrekord. Meanwhile, heavy snowfall that began on Thursday dramatically altered the landscape of Isfahan, blanketing streets, gardens, and historic landmarks.
