The Turkish Meteorological Directorate (MGM) has issued a nationwide forecast of mostly cloudy skies with intermittent downpours and thunderstorms for Thursday, 4 November. The agency highlighted that several provinces will experience particularly intense rainfall, prompting the Istanbul Governor’s Office to issue a specific warning for the capital region.

According to the latest MGM assessment, the most affected areas include Istanbul, Hatay, Adana, Gaziantep, Antalya and Osmaniye. In Hatay’s northern districts, Osmaniye’s central and southern zones, the rain is expected to be “very strong and severe,” while elsewhere the precipitation will be “strong” but more localized.

The Istanbul Governor’s Office emphasized that heavy rain is likely to begin in the early morning hours, with intervals of intense, localized showers throughout the day. Officials urged citizens to stay alert, avoid unnecessary travel, and be prepared for possible flooding in low‑lying neighborhoods.

Temperature ranges for the day are moderate. In Istanbul, highs are forecast at 17 °C with lows around 14 °C. Similar conditions are expected in other western and central provinces: Bursa (12‑18 °C), Çanakkale (13‑14 °C), Kırklareli (11‑12 °C), İzmir (15‑20 °C), Manisa (12‑19 °C) and Muğla (9‑17 °C). In the Mediterranean region, Antalya and Adana will see temperatures between 16‑23 °C and 15‑23 °C respectively, while the southeastern provinces such as Gaziantep, Hatay and Osmaniye will experience highs of 21‑23 °C.

Wind conditions are also a concern. In the Marmara region, including Istanbul, winds from the north and northeast are expected to be strong, with gusts reaching 50‑70 km/h in some spots, potentially escalating to local storm‑force winds. Similar gusts are forecast along the Black Sea coast and in western coastal areas.

MGM also warned of reduced visibility due to fog and mist during the night and early morning in several inland and coastal zones, especially in Central Anatolia and the eastern Black Sea region. Residents are advised to follow local updates and heed any further advisories from municipal authorities.

The weather outlook underscores a pattern of “very cloudy” skies with “intermittent heavy rain and thunderstorms” across much of Turkey on 4 November. Authorities recommend that citizens keep emergency kits ready, secure loose objects outdoors, and stay informed via official channels.
