Turkey Experiences Severe Storms: 5 Regions Warned of Yellow Code Alerts

The Turkish State Meteorological Service (MGM) issued yellow code warnings for heavy rainfall across multiple provinces on June 13, 2026. TRT Haber reports that 34 provinces are under this warning, with the MGM specifically flagging local heavy rain for the Mediterranean region and Anadolu Ajansı reporting alerts for eastern Marmara.

The warnings signal a heightened risk of flash floods and local disruptions as weather systems move across the country. According to the MGM, the Mediterranean region should expect local heavy precipitation. In the north, Anadolu Ajansı reported that the warning extends to the eastern parts of the Marmara region.

Sözcü Gazetesi reports that Istanbul will experience temperatures and weather conditions reminiscent of winter during this period. The outlet indicates that residents should prepare for a significant drop in temperature accompanying the rain.

Which regions are facing the highest risk of rainfall?

The Mediterranean region is a primary area of concern according to the MGM, which warned of localized heavy rain. This pattern of weather often leads to sudden runoff in coastal and mountainous areas.

In the northwest, Anadolu Ajansı confirmed that the eastern Marmara region is under a heavy rain alert. This area includes critical transport hubs and industrial zones, where heavy precipitation can disrupt logistics and commuting.

Istanbul is specifically highlighted by Sözcü Gazetesi as a city that will see “winter-like” hours. The report suggests the rain will be accompanied by a chill that deviates from typical June weather patterns.

What does a yellow code warning mean for residents?

The MGM uses a color-coded system to communicate weather risks. A yellow code is a “be aware” warning, indicating that the weather may cause disruptions to daily life and poses a potential risk to those in vulnerable areas.

While yellow warnings are less severe than orange or red alerts, they serve as a prompt for citizens to monitor official updates. According to TRT Haber, the scope of this specific event is broad, covering 34 different provinces.

How do the reports differ on the scope of the warnings?

Reporting on the scale of the weather system varies across outlets. Diken reported that five provinces were under a yellow code warning, while TRT Haber stated the warning encompasses 34 provinces.

This discrepancy suggests that while a general yellow warning may cover a large swath of the country, specific, high-intensity alerts may be concentrated in a smaller number of provinces. The MGM’s primary alerts focus on the Mediterranean and eastern Marmara as the most active zones for heavy precipitation.

The contrast in reporting highlights the difference between regional weather patterns and localized severe weather alerts. The broad 34-province warning cited by TRT Haber indicates a wide-reaching atmospheric disturbance, while the more targeted reports focus on the regions where the rain is expected to be most intense.
