BERLIN (AP) — Europeans are jumping into public fountains and the sea to keep cool as parts of Europe could see a record-breaking heat wave.

Paris and other parts of France could see temperatures exceeding 40 C (104 F) on Thursday along with Germany, Belgium, Netherlands, Luxembourg and Switzerland.

The heat is putting pressure on authorities to help protect the elderly and the sick. Air conditioning is not common at homes, offices, schools or hospitals in European cities.

The weather is also aggravating droughts since it hasn't rained much in many parts of Europe this summer. The combination of heat, wind, and the risk of lightning from thunderstorms also increases the risk of wildfires such as those blazing in Portugal, according to the World Meteorological Organization.
