Dozens dead in blistering, weeks-long heat wave in Mexico

The extreme heat smothering much of Mexico has killed dozens of people across multiple states over recent weeks, the country's health ministry said in a report published on Thursday, with hotter temperatures forecast for coming days. 

Mexico has been reeling from a high-pressure weather phenomenon known as a "heat dome," which has trapped hot air over much of the country, creating record-breaking temperatures that have surpassed 45 degrees Celsius (113 degrees Fahrenheit) in some places.

Heat-related causes killed 22 people between May 12 and 21, according to preliminary figures shared by Mexico's health ministry.
