By Stephanie Nebehay GENEVA (Reuters) - Refugees and migrants are likely to continue to arrive in Europe at a rate of up to 5,000 per day via Turkey this winter, the United Nations said on Thursday, appealing for more funds to avert tragedy in Greece and the Balkans in coming months. "Harsh weather conditions in the region are likely to exacerbate the suffering of the thousands of refugees and migrants landing in Greece and travelling through the Balkans, and may result in further loss of life if adequate measures are not taken urgently," the U.N. High Commissioner for Refugees (UNHCR) said. "UNHCR’s new winter plan anticipates that there could be up to 5,000 arrivals per day from Turkey between November 2015 and February 2016," it said.
