In San Luis Potosí, authorities are managing water resources and disaster risks during the rainy season. The Comisión Estatal del Agua (CEA) reported that major reservoirs, including San José and El Peaje, are maintaining high capacity levels, which officials state are sufficient to supply the metropolitan area with potable water until 2027. The CEA noted that technical committees will oversee controlled releases if any reservoir exceeds 90% capacity to protect infrastructure.

Concurrently, the National Civil Protection Coordination (CNPC) has issued alerts for 47 of the state’s 59 municipalities—representing 80% of the state—due to medium to very high flood risks. These conditions affect over 2.5 million people, with critical areas identified in Tampamolón and Tamazunchale. The risks include potential landslides and strong winds.

In response, Governor Ricardo Gallardo Cardona and CNPC head Laura Velázquez Alzúa established an Inter-institutional Command Post to coordinate federal, state, and municipal efforts. To bolster response capabilities, the state government announced a co-investment scheme to provide municipalities with emergency equipment, such as ambulances and rapid boats for the Huasteca region. Preventive measures continue to include dredging drainage systems and ensuring hospital readiness. Support from the Mexican Armed Forces via Plan DN-III-E remains a key component of the emergency framework.
