According to MGM’s latest assessment, the wind is expected to blow strongly from the south and southwest in Marmara starting from noon today at 40-60 kilometers per hour. Starting Friday morning, November 13, the wind is forecast to blow as a storm and briefly as a strong storm at 60-90 kilometers per hour.
CALL FROM THE GOVERNORSHIP TO “TAKE PRECAUTIONS”
In its statement based on Meteorology’s assessments, the Istanbul Governorship reported that the lodos will reach 60-70 kilometers per hour from time to time starting from noon today. The Governorship stated that the storm is expected to lose its effect starting from the evening hours of Saturday, November 14, and called for caution against disruptions in transportation, roofs blowing off, and trees and poles falling.
AKOM: THE STORM WILL CONTINUE UNTIL SATURDAY MORNING
In its weekly weather forecast report dated November 11, the Istanbul Metropolitan Municipality (IMM) Disaster Coordination Center (AKOM) announced that the wind in the city would increase in intensity starting Thursday. According to the report, the lodos will blow as a storm until Saturday morning, and at times as a strong storm with short-term gusts. AKOM expects wind speed to be between 40-80 kilometers per hour.
In AKOM’s report, while no precipitation is forecast for the city on Thursday and Friday, it was stated that thunderstorms and showers are expected throughout Istanbul on Saturday, November 14.
“PAY ATTENTION BETWEEN 09.00 AND 15.00 TOMORROW”
Meteorology Expert Adil Tek said that no precipitation is expected in Istanbul today, and that the wind occasionally rises to 40-50 kilometers per hour. Tek stated that the storm will strengthen further tomorrow, and said, “Especially tomorrow between 09.00 and 15.00, the storm’s speed over the sea may reach up to 90 kilometers per hour.”
Expressing that the lodos will carry the warm air in the south to the region, Tek conveyed that temperatures in Istanbul will rise up to 21-22 degrees tomorrow and Saturday.
FERRY SERVICES MAY BE CANCELLED
Tek warned that due to the strong lodos, cancellations may occur in ferry services across the Sea of Marmara, especially in the afternoon hours. In air transportation, he stated that rather than cancellations, landing and takeoff intervals will lengthen due to strong wind, and this may cause delays. Passengers using sea and air routes are advised to check their services.
ON SATURDAY, TEMPERATURES WILL SUDDENLY DROP BY 7-8 DEGREES
Saying that a sharp change in the weather is expected over the weekend, Tek noted that a new cold front will pass from the north on Saturday afternoon. Tek stated that during the front passage, 30-40 kilograms of precipitation per square meter may fall within half an hour, and temperatures will rapidly decrease by 7-8 degrees at once.
Emphasizing that caution should be taken against lightning, thunderbolts and thunderstorms on Saturday afternoon and evening, Tek noted that the system will leave Istanbul on Sunday morning, but new precipitation is expected next week.
WHAT WILL THE WEATHER BE LIKE ACROSS THE COUNTRY?

Showers and thunderstorms are expected around the Coastal Aegean and Antalya, Bartın, Sinop and Samsun. In the morning and night hours, haze and in places fog will be seen in Marmara and the inland and eastern parts.
