NELAS, Portugal: Four people have died so far in wildfires raging in central and northern Portugal and over 40 have been injured, state news agency Lusa reported on Tuesday, as authorities evacuated more villages overnight.
The civil protection authority accounted for three deaths as of Monday night and would not comment on Lusa’s report.
More than 1,000 firefighters worked through the night to control a cluster of four blazes in the northwestern Aveiro district.
Reuters footage showed local residents pouring buckets of water on advancing flames near the town of Nelas about 50 km (31 miles) east of Aveiro.
There were 48 active wildfires in mainland Portugal mobilizing around 5,000 firefighters.
In Aveiro alone, the blazes have burned through more than 10,000 hectares (24,710 acres) of forest and scrubland in the past two days, officials said, roughly the same acreage that was consumed by fires through the end of August in the entire country.
National emergency and civil protection commander Andre Fernandes said late on Monday the Aveiro fires could engulf a further 20,000 hectares.
Authorities have closed several motorways, including a stretch of the main highway linking Lisbon and Porto, and suspended train connections on two railroad lines in northern Portugal.
Portugal and neighboring Spain have recorded fewer fires than usual after a rainy start to the year, but both remain vulnerable to the increasingly hot and dry conditions that scientists have blamed on global warming.
Temperatures topped 30 degrees Celsius (86 degrees Fahrenheit) across the country over the weekend, when the fires first broke out and were fanned by strong winds. The meteorology agency IPMA forecasts they would stay above 30 C (86 F) for the next two days, amid extremely low humidity.
The danger of fires will remain ‘high, very high or maximum’ in the northern and central regions, it said.
“We need to be realistic. We will have difficult hours in the coming days and we have to get ready for it,” Prime Minister Luis Montenegro told reporters on Monday night.
The government on Monday requested help from the European Commission under the EU civil protection mechanism, leading Spain, Italy and Greece to send two water-bombing aircraft each.
