Turkish State Meteorological Service issued a yellow alert for Istanbul, forecasting cooler temperatures, rainfall and overcast skies that break the recent heat while raising flash flood risks across the European side and neighboring Thrace region.

Why the Alert Matters for Daily Movement

The warning follows torrential rain that flooded several districts just days earlier, leaving residents and commuters to weigh options for avoiding waterlogged roads and disrupted services. Officials stressed that heavy downpours could trigger flash floods, waterlogging, lightning, transportation disruptions and strong winds, urging everyone to exercise caution during the period.

Details from AKOM and Meteorological Service

The Istanbul Municipality’s Disaster Coordination Center (AKOM) specified that heavy local thunderstorms would affect different parts of the city, with northerly winds bringing a noticeable temperature drop. The alert also covers the northwestern provinces of Çanakkale, Edirne, Tekirdağ and Kırklareli.

Recent Flood Impact in Üsküdar

Among the hardest-hit areas in the prior weekend event was the secondhand booksellers’ market in the Üsküdar district, where floodwaters inundated shops and damaged books. This recent episode underscores why the current yellow alert requires attention to localized risks on the European side.

Key Decisions Ahead for Residents

With thunderstorms expected to intensify in the afternoon, residents must decide on routes that avoid low-lying or previously affected streets, monitor updates from AKOM, and prepare for possible delays in public transport. The service advises limiting outdoor exposure during peak rainfall hours and securing property against water ingress where feasible.
