In the Turkish region around the epicenter of the first quake, heavy rain is expected, while temperatures will be only 3-4C during the day and well below freezing at night. Around 3-5cm of snow is also set to fall, while further north in Turkey, heavier snow is expected. In more mountainous regions, temperatures are not expected to rise above freezing at all in the coming days, which could mean snowfall of 50-100cm. At least 2,800 buildings are thought to have been destroyed in this morning's first quake, meaning many thousands of people could be left without shelter. — BBC
