The polar blast affecting much of South America's Southern Cone has claimed its first mortal victims in Brazil, authorities said Wednesday.
A 45-year-old homeless man was found dead late Tuesday in Sao Paulo, Brazil's largest city, where the temperature climbed only to 10 C (50 F) - the coldest daily maximum in four years - before falling to 8.3 C (47 F) after sunset.
Sao Paulo's lowest temperature ever is 7.3 C (45 F), recorded on July 12, 1988.
The other fatality reported Wednesday was also a homeless man, a resident of Curitiba, capital of the southern state of Parana, who died amid overnight temperatures of minus 1.3 C (30 F).
The Sao Paulo municipal government said that despite an increase in the number of beds at homeless shelters to 11,800, the facilities were unable to accommodate everyone seeking to come in from the cold.
Around 20,000 people, including families with children, are sleeping on the streets of Sao Paulo, according to the Rev. Julio Lancelotti, coordinator of homeless outreach for Brazil's Catholic bishops conference.
A number of towns in southern Brazil experienced record low temperatures on Wednesday and some areas had snow and frost.
Bom Jardim da Serra, a town in the mountains of Santa Catarina state, posted an overnight low of minus 8.8. C (16 F).
The weather forecast calls for the unusually temperatures to hang on for one more day.
Comment: There's some doubt on the bear attack theory. Any farmer in the Pyrenees with sheep dead from unknown causes, i.e. where they are found dead with no evidence of animal attack, would most likely try to push the "bear said boo!" angle. These kinds of government/EU subsidies and compensation have been exploited by farmers and others across the EU for decades.
Although a bear attack can't be ruled out, we can suspect that the incident was created by a "weather event" or something that created a high impact explosion, like a sonic boom or lightning strike. Sheep have acute hearing and are prone to "instantly scatter" away from heavy percussion and the source of the vibration. Many of the sheep were found to have dispersed over the mountains. It's dubious that a bear attack would create that type of a reaction.
On the other hand, the Spanish news agency Europa Press said that bear fur had been found on one of the dead sheep. The fur would be analysed to try to establish exactly what had happened. But this is a bit strange that bear fur can be found so opportunely on a sheep. Another possibility is that the bear didn't come along afterwards and the sheep were spooked by something else.
