BEIRUT — A winter storm packing heavy rain and snow on Tuesday turned streets in Lebanon into rivers of water and mud and paralyzed parts of the country.

Among those affected were tens of thousands of Syrian refugees, many of whom live in tent settlements. In the eastern Bekaa Valley, many Syrian refugees stayed indoors next to diesel or wood heaters as snow covered their flimsy tents.

Authorities closed the highway linking Beirut with the Syrian capital Damascus after parts of it that cut through high mountains became covered with snow.

In the coastal town of Dbayeh, just north of Beirut, part of the highway was closed after it was filled with water. Rescuers later used small boats to help people stranded in their cars.

Most schools were closed Tuesday and the Lebanese education minister called for school to be closed even on the coast for a second day Wednesday.

On Monday, a woman gave birth in an ambulance as it took a long time to reach a hospital because of snow. The woman and the baby later arrived at the nearby hospital and both are in good health, according to state-run National News Agency.

The storm dubbed "Norma" began Saturday and is expected to reach its peak Tuesday night.
