Storm Alert: Red-Zone Areas and Rainfall Forecasts for Athens and Glyfada on Sunday

Meteorologists and the Hellenic National Meteorological Service (EMY) issued an emergency weather warning on Saturday, 31 January 2026, forecasting severe weather across nine Greek regions on Sunday, 1 February. The storm will bring persistent thunderstorms, torrential rain, gale-force winds, snow in mountainous areas, and a slight temperature drop. Forecaster Theodoros Kolydas detailed the expected impacts on social media, highlighting rainfall totals for Attica and Thessaly—and special attention to Glyfada, still recovering from a recent deadly storm that claimed the life of a 56-year-old woman. The system moves west-to-east, delivering heavy moisture. In Attica, intense rain and strong winds in the Saronic Gulf are expected early Sunday morning; Thessaly faces prolonged, high-intensity rainfall. Athens is forecast to receive 28 mm in 24 hours (up to 50 mm in worst-case scenarios); Glyfada expects 21 mm (peaking at 48 mm). Snow is expected in mainland mountainous and northern semi-mountainous areas—and from late Sunday afternoon, even in low-elevation parts of Eastern Macedonia and Thrace. By Monday, conditions ease—only Crete and the Dodecanese will see isolated thunderstorms. EMY’s alert includes red warnings for Peloponnese, Macedonia, and Thessaly; orange warnings for Crete, Ionian Islands, Epirus, Sterea Ellada, eastern Aegean islands, and the Dodecanese. Meteo.gr maps show escalating intensity: first over southwestern Peloponnese, then Thessaly and northern Evia, finally affecting northeastern Aegean islands by Sunday night before gradually weakening.
