The upper level trough created a frontal cloud system which brought a lot of snow to Turkey and heavy snow showers to Crete, Cyprus, Lebanon, Israel and Syria (seen in Natural Colours RGB). A pre-frontal dust outbreak can also be seen over Syria, Iraq, Jordan and Saudi Arabia (see Dust RGB).

The following images show the situation over Turkey the day after the heavy snowfalls, caused by the cyclone, crossed the area on 7 January. As usual when cold Russian air moves across warm water, cloud streets form over the Black Sea. These cloud streets are better seen in the HRV image (channel 12 of SEVIRI) which has a three times better resolution than the Natural Colour RGB image that uses the solar channels NIR1.6, VIS0.8 and VIS0.6 (channels 3, 2 and 1 of SEVIRI).

In the Suomi-NPP INCOL image taken at 10:38 UTC the cloud streets are clearly visible and it also shows a low concentration of sea ice for the season in the Sea of Asov.
