In Punta Arenas, authorities maintained a communal Red Alert following intense rainfall and river overflows. While water levels in major rivers decreased, the regional Committee for Disaster Risk Management (Cogrid) sustained the preventive measure due to ongoing flooding risks. 

The Ministry of Public Works monitored critical hydraulic infrastructure, including the Llau Llau and D’Agostini estuaries, the Las Minas River, and the Tres Puentes wetland. Specific impacts were noted in the San Juan River and the Ojo Bueno sector. As a precaution, the Magallanes National Reserve was closed to visitors.
