Travellers and residents on Türkiye's eastern Mediterranean coast should plan around an official thunderstorm warning on Friday, 18 September. MGM expects intermittent, locally strong showers and thunderstorms in the coastal parts of Mersin, Adana and Hatay until 17:00. Flash flooding, lightning, local hail, short strong gusts and transport disruption are among the stated risks. The bulletin does not announce a general airport, flight, road or school closure.
Where and when the warning applies
MGM warning No. 462 is valid from 00:00 to 17:00 on 18 September and refers specifically to coastal parts of Mersin, Adana and Hatay. It forecasts intermittent showers and thunderstorms that may become locally strong. The wording does not mean continuous heavy rain across every district for the entire period.
What the official risk list includes
The meteorological service lists flash floods, urban flooding, lightning, disruption to transport, local hail, short-lived strong winds and a coastal tornado or waterspout risk. Conditions can change quickly around low-lying roads, underpasses, stream beds, beaches and marina approaches even when nearby locations remain dry.
Flights and roads: check the individual service
The warning covers a corridor used for travel through Mersin, Adana and Hatay, but it is not a cancellation notice. Passengers should check their exact flight with the airline and airport before departure, while drivers should confirm the live route with the responsible road or municipal authority. Never drive into standing or moving floodwater.
Advice for visitors on the coast
Postpone exposed beach, boat or waterfront plans while thunder is nearby, keep away from stream mouths and do not shelter beneath isolated trees. Confirm excursions with the operator shortly before leaving and ask how the return journey will be handled if a local road becomes impassable. A local cancellation may be narrower than the three-province warning.
What residents can do before the strongest cells
Secure balcony furniture and loose outdoor items, keep vehicles away from flood-prone underpasses and move important documents or electronics out of basements and ground-level storage. Follow MGM, AFAD, the provincial governorate, municipality and transport provider for incident-specific instructions. Call 112 only for an emergency.
