UNHCR launches an appeal to fund the Winterization Plan for the Refugee Crisis in Europe, November 2015 – February 2016.

"The plan focuses on putting in place measures to support affected countries such as Croatia, Greece, Serbia, Slovenia and the former Yugoslav Republic of Macedonia, in order to avert the risk of humanitarian tragedy and loss of life during the winter months," UNHCR spokesperson William Spindler said. UNHCR's new winter plan anticipates as many as 5,000 arrivals to reach Greece each day from Turkey between November 2015 and February 2016.
