The Federal Aviation Administration said Saturday that a flight from Denver to Mexico City will be canceled because of a heat wave and the U.S. Centers for Disease Control and Prevention have warned people to take precautions.
The U.K.’s National Health Service said people should stay indoors and stay out of heat if they are traveling to northern parts of Europe.
It is also advising travelers to stay away from areas where a high heat index has been recorded, such as the Sahara Desert, which has been declared a heat island.
The FAA has warned that heat wave conditions can lead to heat exhaustion, dehydration, heat stroke and other health problems.
The agency said Saturday there are no immediate plans to cancel flights.
The CDC has said heat wave weather in Mexico could be the worst it has seen in several decades.
The National Weather Service says the heat is expected to drop to 40 degrees by Sunday.
The heat is predicted to persist through at least Monday, possibly reaching the 70s, according to the National Weather Center.
Weather experts say the weather pattern could bring cooler temperatures and longer periods of sunny days.
Weather conditions are expected to continue to be hot, with temperatures expected to average 90 degrees, the weather center said.
The weather center is warning that this week will be “worse” than previous weeks.
The average high temperature across much of the U, U.A.C., and Mexico is expected by Tuesday to be 90 degrees.
