Austrian authorities declared avalanche alerts Sunday as heavy snowfalls blocked roads and rail segments and left thousands of homes without electricity.

Across Italy's northern Emilia-Romagna region, rising rivers prompted evacuations as the north's main conduit, the river Po, rose 2.5 meters (8 feet) in 24 hours.

Schools in Austria's East Tirol and Carinthia were ordered closed for Monday as Tirolian avalanche expert Rudi Mair warned that moist snow slabs could slide.

The falls coincided with hefty debate across alpine Europe about banning skiing to minimize coronavirus contacts.

At the Brenner Pass, 90 centimeters of snow were recorded. Rail traffic through to the Italian city of Bozen was halted because of landslide and avalanche risks.

In Italy's Dolomite and South Tirol regions, rescue services were called out hundreds of times. Houses were evacuated in Emilia-Romagna as the river Panaro overflowed its banks.
