The Spanish government will send convoys carrying COVID-19 vaccines and food supplies to areas cut off by Storm Filomena, which brought the heaviest snowfall in decades across central Spain and killed four people.
Crews are clearing snow across Spain after the rare blizzard impacted 430 roads and stranded hundreds of travellers at Madrid's Barajas airport.
One man and a woman in a car drowned after a river burst near Malaga in the south, while two homeless people froze to death in Madrid and Calatayud in the east, officials said.
"The commitment is to guarantee the supply of health, vaccines and food. Corridors have been opened to deliver the goods," transport minister Jose Luis Abalos said on Sunday.
Forecasters warned of dangerous conditions in the coming days, with temperatures expected to fall to up to -10C next week and the prospect of snow turning to ice and damaged trees falling.
About 100 workers and shoppers have spent two nights sleeping at a shopping centre in Majadahonda, a town north of Madrid, after they were trapped by the blizzard on Friday.
"There are people sleeping on the ground on cardboard," Ivan Alcala, a restaurant worker, told TVE television.
Dr Alvaro Sanchez walked 17 km through the snow on Saturday to work at a hospital in Majadahonda, prompting owners of 4x4 vehicles to give health workers lifts to work.
Train services from Madrid, which were cancelled since Friday, resumed on Sunday.
The State Metereological Agency said up to 20-30 cm of snow fell in Madrid on Saturday, the most since 1971.
