Severe weather and environmental issues have caused significant property damage in Colombia and Mexico. In Puerto Colombia, coastal erosion driven by heavy rains and strong waves led to the collapse of 20 homes, with 10 more at risk. Local authorities have implemented rock armor as a temporary measure, though community leaders are advocating for permanent jetties.

In Mexico, intense rainfall in San Pedro de las Colonias damaged approximately 100 homes and a school. In Zapotitlán, authorities are seeking state intervention to relocate 12 families due to beach erosion that has left homes on the verge of collapse. Municipal agent Israel González Lorenzo noted that the community lacks available land for these relocations. In Ensenada, Mayor Claudia Agatón has requested assistance from Conagua to clean the La Munguía and del Gallo streams to prevent further damage following previous weather events that rendered over 280 homes uninhabitable. Local administrations are conducting censuses in high-risk areas like El Salitral and Lomas de San Fernando to manage resources.

Recent incidents have expanded the scope of the crisis. In the Jacarandas neighborhood of El Vigía, Mexico, residents reported sewage leaks causing stomach illnesses and exposed electrical cables posing shock risks. In the Palmor district of Ciénaga, Colombia, an avalanche of mud, stones, and vegetation entered several homes, flooding streets and forcing evacuations. Community leaders there have requested urgent assistance from the National Unit for Disaster Risk Management (UNGRD), Civil Defense, the National Police, and the Fire Department to coordinate emergency responses.
