Global regions continue to experience diverse and extreme meteorological events. Initial reports indicated heatwaves and storms in Spain, where the Mediterranean Sea reached record temperatures, alongside heavy rains in Mexico and varying winter patterns in Argentina. Weather severity has intensified across the Americas. In the United States, the NHTSA has issued alerts regarding flash flooding and its potential impact on national highways following severe storms, tornadoes, and lightning that caused fatalities in Indiana and Ohio. In Mexico, the impact of extreme heat has escalated significantly, with a severe heatwave resulting in 75 deaths and over 1,600 people affected nationwide. The state of Veracruz has reported five heatstroke deaths and 58 medical cases related to heat and dehydration, ranking third in the country for “climate-related lethality.” Simultaneously, the Mexican monsoon is driving heavy to very heavy rainfall across the northwest, including Chihuahua, while causing instability in central and southern regions. In Guatemala, unusual heavy hailstorms covered parts of the western highlands, including Olintepeque and San Andrés Xecul, in ice. This has prompted emergency protocols to assess potential damage to infrastructure and crops. Meanwhile, Argentina has issued alerts for extreme cold in Jujuy. ## Claims - The Mexican monsoon is causing heavy rains in the northwest, including very heavy rainfall in Chihuahua.
