Argentina has experienced significant meteorological instability characterized by widespread storms and the Zonda wind phenomenon. Initially, the National Meteorological Service issued orange alerts for heavy storms, hail, and wind gusts exceeding 100 km/h in regions including Chubut and the AMBA area. Concurrently, the Zonda wind brought high temperatures and extreme dryness to San Juan, increasing forest fire risks. As the weather patterns progressed, the Zonda wind specifically impacted the provinces of San Juan and Mendoza. In San Juan, wind gusts prompted a yellow alert, leading the Liga Sanjuanina de Fútbol to suspend all scheduled matches for Sunday to ensure safety. In Mendoza, the wind affected the Greater Mendoza area, San Rafael, Malargüe, and the Uco Valley, with gusts forecasted between 40 and 45 km/h. ~~Conditions were expected~~ Recent developments show a cold front triggering widespread alerts across the country.
