ANKARA, Turkey (AP) — Forest fires fanned by high winds and hot, dry weather damaged some holiday homes in Turkey as a lingering heat wave that has cooked much of Europe led authorities to raise warnings and tourists to find ways to beat the heat on Monday.

A heat dome hovered over an arc from France, Portugal and Spain to Turkey, while data from European forecasters suggested other countries were set to broil further in coming days. New highs are expected on Wednesday before rain is forecast to bring respite to some areas later this week.

“Extreme heat is no longer a rare event — it has become the new normal,” tweeted U.N. Secretary-General António Guterres from Seville, Spain, where temperatures were expected to hit 42 Celsius (nearly 108 Fahrenheit) on Monday afternoon.

Reiterating his frequent calls for action to fight climate change, Guterres added: “The planet is getting hotter & more dangerous — no country is immune.”

In France, which was almost entirely sweltering in the heatwave on Monday and where air conditioning remains relatively rare, local and national authorities were taking extra effort to care for homeless and elderly people and people working outside.

Some tourists were putting off plans for some rigorous outdoor activities.

“We were going to do a bike tour today actually, but we decided because it was gonna be so warm not to do the bike tour," said Andrea Tyson, 46, who was visiting Paris from New Philadelphia, Ohio.

Authorities in Portugal issued a red heat warning for seven of 18 districts as temperatures were forecast to hit 43 degrees Celsius, a day after logging a record June temperature of 46.6 degrees C. Almost all inland areas were at high risk of wildfires.

In Turkey, forest fires fanned by strong winds damaged some holiday homes in Izmir’s Doganbey region and forced the temporary closure of the airport in Izmir, the state-run Anadolu Agency reported. Authorities evacuated four villages as a precaution, the Forestry Ministry said.

In Italy, the Health Ministry put 21 cities under its level three “red” alert, which indicates “emergency conditions with possible negative effects” on healthy, active people as well as at-risk old people, children and chronically ill people.

Regional governments in northwestern Liguria and southern Sicily in Italy put restrictions on outdoor work, such as construction and agricultural labor, during the peak heat hours.

In southern Germany, temperatures of up to 35 degrees Celsius (95 Fahrenheit) were expected on Monday, and they were forecast to creep higher until midweek – going as high as 39 degrees (102F) on Wednesday.

Some German towns and regions imposed limits on how much water can be taken from rivers and lakes.
