Photos From Europe's Deadly Heat Wave

The U.K.'s heat wave continued to disrupt travel for a third day on Wednesday even as temperatures began to come down. London is expected to reach a high of 79 degrees Fahrenheit on Wednesday, but the main train line from London to Edinburgh remains closed until noon due to heat-damaged power lines and signaling equipment.

Firefighters in the U.K. remain on alert after the London Fire Brigade experienced its busiest day since World War II on Tuesday. Locals made more than 2,600 calls to the brigade and firefighters were at one point fighting 12 fires simultaneously, according to Mayor Sadiq Khan. At least 41 homes were destroyed in the blazes, The Associated Press reported.

The country smashed previous all-time record highs Tuesday three times as the day's temperatures grew hotter and hotter, with temperatures eventually reaching 104.4 degrees Fahrenheit in Coningsby in eastern England. The first record high of the day beat a previously held 2019 record. The temperature continued to rise, beating the record set earlier in the day twice.

A large wildfire broke out about 16 miles northeast of Athens Tuesday, and nearly 500 firefighters were continuing the fight on Wednesday after hundreds of residents were forced to evacuate overnight.

Firefighters were reporting improved conditions as temperatures lowered throughout Spain, Portugal and France, where heat-fueled wildfires had been burning for the past several days. The Associated Press reported at least 1,000 heat-related deaths out of Spain and Portugal, where temperatures reached 117 degrees Fahrenheit earlier this month.
