Sources: 81. Developments: 5. Recent developments highlight ongoing challenges posed by weather and infrastructure maintenance. In Michoacán, Mexico, officials conducted canal cleaning in La Concepción and between La Mintzita and San Juanito Itzícuaro to prevent flooding from sediment buildup. In Querétaro, Mexico, a structural collapse occurred during the Peñuelas drain reconstruction. In Chile, heavy rains caused a failure on Route 504 in the Tarapacá region, restricting it to light vehicles, and led to the clearing of a collapsed storm drain in Concepción’s Villa Huáscar sector. Additionally, the Dirección del Trabajo ordered the total closure of Mall Plaza Centro in Antofagasta due to electrical installations being exposed to rainwater, posing risks to workers. Infrastructure projects have also triggered social and economic friction. In San Luis Potosí, Mexico, local merchants reported that construction on the San Luis-Matehuala highway has impacted over 260 businesses, with some seeing sales decreases of up to 70 percent due to traffic being diverted to toll roads. Governor Ricardo Gallardo Cardona claimed these protests are driven by the interests of a single individual with gas station businesses, though merchants maintain the impact is widespread. In Chile, residents in Llay Llay and Aconcagua expressed dissatisfaction following the removal of the Las Vegas toll plaza. The change eliminated local turnarounds and passenger stops, forcing commuters to travel to the Ocoa sector and pay tolls twice. Provincial Presidential Delegate Sebastián Caldera stated the government is working with the Ministry of Public Works to find solutions after previous meetings failed to satisfy community demands. ## Claims - Valparaíso health service warned residents about fire and carbon‑monoxide risks from indoor heating during upcoming rains.
