Moscow Hit by Historic Late-April Blizzard Breaking a 146-Year-Old Record

An unexpected Arctic snowstorm buried Moscow overnight, snapping power lines, grounding flights, and breaking a snowfall record that had stood since 1880 all while spring was supposed to be in full swing.

A City Caught Off Guard

Moscovites woke up Monday morning to something nobody expected a city buried under a thick white blanket of snow. A rare and powerful late-April winter storm rolled into the Russian capital overnight, catching residents completely off guard. Local authorities wasted no time issuing warnings heavy snow and fierce winds would continue battering the city for at least two more days.

Numbers That Tell the Story

Between Sunday night and Monday morning, Moscow recorded around 21 millimeters of precipitation. Yevgeny Tishkovets, chief meteorologist at the Phobos weather centre, confirmed this figure. In practical terms, that translates to roughly 21 centimetres or about 8.3 inches of snow blanketing the city in just hours. Tishkovets made the significance of the event crystal clear, writing on Telegram: “Never in the entire history of meteorological observation has there been this much snow on April 27.” The previous daily snowfall record dated all the way back to 1880 and Monday’s storm blew past it decisively.

Power Cuts, Fallen Trees, and Gridlock

The sheer weight of the snow caused widespread destruction across the city and its surroundings. Trees toppled across Moscow’s streets, and snapping power lines cut off electricity to 50 villages in the surrounding Moscow region. Commuters faced hours stuck in bumper-to-bumper gridlock as roads became treacherous. Several airports temporarily suspended flights due to dangerous weather conditions. City authorities raised an “orange” weather advisory the second-highest alert level on the scale underscoring the storm’s severity.

Two Lives Lost on the Roads

The storm also turned deadly. Two people lost their lives in a collision between a truck and a passenger vehicle on a highway in the southeastern part of the Moscow region, near the Ryazan border.

48 More Hours of Winter

There is no quick end in sight. Forecasters say the wintry system will hang over the region for another 48 hours. Moscow Mayor Sergei Sobyanin personally urged residents to stay alert, warning of more wet snow and wind gusts reaching up to 23 metres per second roughly 50 miles per hour.

What Caused This? Blame the Omega Block

Meteorologists across Europe point to an unusual atmospheric phenomenon a so-called “Omega block” sitting over the North Atlantic. This stubborn high-pressure system essentially acted as a funnel, channelling a mass of frigid Arctic air deep into Eastern Europe. The rare pattern allowed polar air to sidestep the usual westerly winds entirely. That Arctic air then collided head-on with the region’s early-spring warmth and the result was an explosive, record-breaking winter storm in late April.
