The meteorological shift in Turkey began in late August 2026, as a new weather system from the north replaced prolonged heatwaves with thunderstorms and cooler temperatures. By early September, flooding in the Black Sea region, particularly in Ordu, prompted calls for national solidarity. Throughout September, the country experienced extreme regional contrasts, with southern provinces like Muğla and Antalya maintaining summer-like heat while the Black Sea coast faced ‘yellow code’ warnings for flooding and landslides. In mid-October, the transition escalated into a historic disaster in Istanbul, where rainfall reached levels described as the highest since ~~1942, causing~~ 1942. This extreme weather caused at least ~~four deaths~~ three deaths—including a 14-year-old electrocution and ~~the collapse of the Çaylak Bridge. By mid-October, widespread severe weather continued. In Istanbul,~~ a fall in the ~~AKOM disaster coordination center warned of powerful storms with wind speeds between 50 and 80 km/h, while 13 districts faced heavy precipitation. In Adıyaman,~~ Sariyer district—and left five people missing. The flooding caused ~~road collapses and stranded vehicles,~~ significant infrastructure damage, diverted 46 flights, and ~~Yalova~~ forced residents to seek refuge on bus roofs. In response, authorities suspended in-person education in Istanbul and neighboring provinces like Kocaeli, Sakarya, Yalova, and Zonguldak, while deploying over 46,000 personnel for ~~one day. Authorities also~~ rescue operations. By mid-to-late October, the weather pattern shifted toward seasonal transitions. Significant snowfall arrived in provinces such as Bursa and Ankara, while Istanbul’s dam occupancy rates rose by over 14 percentage points due to recent rains. Meteorological experts warned of ~~dust transport from Syria affecting Southeastern Anatolia.~~ a highly variable winter driven by El Niño and the Polar Vortex. As October progressed, ~~volatility remained high. By late October,~~ the General Directorate of Meteorology issued widespread warnings for ~~widespread~~ heavy ~~rainfall and~~ thunderstorms ~~expected to impact~~ and intense precipitation across the ~~Aegean~~ Aegean, Mediterranean, and ~~Mediterranean coasts, including~~ Marmara regions, specifically targeting Muğla, Aydın, and ~~western~~ Antalya, as well as the Marmara region. While western temperatures were expected to drop below seasonal norms, eastern regions remained near or slightly above averages.
