Spain, Portugal, and Greece battle wildfires as heatwave is expected to last for days

Villar) MADRID — Firefighters in Spain, Portugal and Greece continued to battle wildfires Friday on a public holiday in all three countries as persistent hot, dry conditions challenged efforts to contain the blazes. Spain was fighting 14 major fires. Temperatures were expected to climb over the weekend. 'Today will once again be a very tough day, with an extreme risk of new fires,' Spanish Prime Minister Pedro Sánchez wrote on X. The national weather agency AEMET warned of extreme fire risk in most of the country, including where the largest blazes were burning in the north and west. A heatwave which brought temperatures exceeding 40 degrees Celsius (104 Fahrenheit) on several days this month was expected to last through Monday. Fires in the Galicia region forced the closure of several highways. The high speed rail line connecting it to Spain's capital, Madrid, remained suspended. The fires in Spain this year have burned 158,000 hectares or 610 square miles, according to the European Union's European Forest Fire Information System. That is an area roughly as big as metropolitan London. In both Spain and Portugal it was the Feast of the Assumption, a major Catholic holiday usually marked by family gatherings and religious processions. In Portugal, nearly 4,000 firefighters were battling seven major fires. Authorities extended the state of alert until Sunday, amid high temperatures expected to last through the weekend. A wildfire in Greece burned out of control for a fourth day on the island of Chios, prompting several more overnight evacuations. Two water-dropping planes and two helicopters were operating in the north of the island in the eastern Aegean Sea, where local authorities said a lull in high winds was helping firefighters early Friday. Following a series of large fires in western Greece earlier this week, the Fire Service was on alert Friday outside Athens and nearby areas in the south of the country where adverse weather conditions elevated the fire risk. The spiritual leader of the world's Orthodox Christians Ecumenical Patriarch Bartholomew expressed solidarity on Friday with the victims of wildfires in southern Europe during prayers for the Dormition of the Virgin Mary, an important religious holiday for Orthodox Christians. ___ Suman Naishadham, The Associated Press AP writer Derek Gatopoulos contributed from Athens.

Florence and the Machine were right: The dog days (of summer) are over, at least for this year
It's official: The dog days of summer are over. At least, astronomically speaking. "This term the dog days of summer goes back all the way to actually past ancient Greece, even into ancient Egypt and all of it is in reference to a star that's the brightest star in our system called Sirius, which is the dog star," says Orbax, a science communicator with the University of Guelph and who is one part of the science entertainment duo Orbax and Pepper Do Science. Sirius, known as the dog star, was brightest between July 3 to Aug. 11 when viewed in southern Ontario, the U.S. National Weather Service says on its website, "which is 20 days prior and 20 days after the star Sirius rises and falls in conjunction with the sun." But the saying has also been linked to the hottest days, and Orbax says that has led to lore about the star and the weather. "It's one of these stars that actually consistently rises and sets at the same times every year. So when it would come up early in the morning, ancient civilizations would link this idea to almost like having an extra sun," Orbax said. He added that it was also that time in August where grass and foliage might be dying in the heat, "and we'd all feel pretty beat down because my understanding is that in ancient Greece, there was a pretty severe lack of air conditioning." Downward trend to the cold days of winter Turns out, the dog days of summer are also waning weather–wise. Steven Flisfeder, a meteorologist with Environment and Climate Change Canada, says "unofficially you can think of the dog days of summer as the absolute peak in terms of temperatures, so when we're, climatologically speaking, expected to be the absolute hottest before we start our gradual decline in toward the fall," he said. He says the weather often lines up with Sirius being bright in the sky with the hottest days in late July and early August. So now, how do the dog days stand as of Aug. 15? "Climatologically speaking, every day is going to be different, but in general it is a downward trend from here on out," Flisfeder said. As well, meteorological summer is getting set to wrap up at the end of the month. "The meteorological seasons always start on the first day of their respective month. So for summer, it starts June 1, for fall, it starts September 1. And the very basic reason for that is that it's statistically convenient," he said. But even if summer is coming to a close, Flisfeder notes it doesn't mean sweater weather begins on Monday, Sept. 1. "We can still have warm temperatures toward the end of summer even into the early parts of fall. We've had heat events through to the end of September," he said.
