LISBON, Portugal >> Eight places in the center, south and east of Portugal broke their local temperature records as a wave of heat from Africa swept across the Iberian peninsula, with officials forecasting today it would continue and possibly worsen over the weekend.

Temperatures built to around 45 degrees in many inland areas of Portugal today, and were expected to peak at 47 degrees in some places on Saturday. Large parts of Portugal are on red alert on the Civil Protection Agency’s danger scale.

The highest temperature recorded Thursday, when the heat began to rise, was 45.2 degrees Celsius (113.4 Fahrenheit) near Abrantes, a town 150 kilometers (93 miles) northeast of the capital, Lisbon, the country’s weather agency IPMA said.

Portugal’s highest recorded temperature was 47.4 degrees (117.3 Fahrenheit) in 2003. Emergency services have issued a red alert, placing extra services such as medical staff and firefighters on standby through Sunday.

In Portugal’s southern Alentejo province, streets were largely deserted and some farmers chose to work during the night. Beaches around Lisbon, meanwhile, were packed.

Some 400 firefighters and five water-dropping aircraft were battling a wildfire in southern Portugal’s Algarve region.

Portugal sees large wildfires every year, although unseasonably cool weather through the end of July has meant fewer blazes in 2018. The government says only about 15 percent of the 10-year average area has been charred so far this year.

Temperatures were being driven higher across the Iberian peninsula by a hot air mass moving northward from Africa, which is also bringing dust from the Sahara Desert, meteorologists said. The dust gave the sky a dark yellow hue in some places.

In Spain, heat warnings were also issued for 41 of the country’s 50 provinces as temperatures were expected to reach up to 44 degrees Celsius.

Summer temperatures close to 40 degrees Celsius are not unusual in southern parts of the Iberian peninsula.

Spain’s highest recorded temperature is 46.9 degrees Celsius in Cordoba, a southern city, last July.

The World Meteorological Organization says continental Europe’s record is 48 degrees Celsius in Greece in 1977.

In northern Europe, Sweden was still under threat from wildfires, which in recent weeks have extended into the Arctic Circle.

Sweden’s Civil Contingencies Agency warned of “a high risk” for wildfires in central and southern Sweden this weekend because of the continuing dry weather and strong winds.

An unusually long, torrid summer in Britain, meanwhile, has taken its toll on the country’s flowers. Supermarket chain Morrisons has begun selling “wonky” flowers that have not developed properly.

The U.K.’s Met Office weather service says July was the country’s third-warmest in more than a century. The hot weather is continuing, with temperatures forecast to reach 30 degrees Celsius in southern Britain today.
