Puerto Vallarta authorities issued a red alert and urged residents to stay indoors on Sunday due to violent incidents and road closures linked to cartel activity.

Unverified reports linked the operation to the Jalisco New Generation cartel and its leader, El Mencho, though officials had not yet provided confirmatory details.

A travel warning was issued for Puerto Vallarta and other areas in Jalisco, plus regions in Tamaulipas, Michoacán, Guerrero, and Nuevo León.

The federal operation in Jalisco state sparked clashes and heightened security concerns that prompted the travel advisory for parts of Mexico, including Puerto Vallarta.

The Mexican government issued a Code Red to safeguard the public, advising residents and visitors to avoid leaving their homes or resorts amid ongoing security operations.

Authorities advised avoiding non-essential travel, staying away from areas with police or military presence, and monitoring official updates for emergency instructions.

Clashes occurred in Tapalpa as vehicles were burned or blocked across the region to hinder authorities, with the security situation described as spreading and evolving with new blockades.

The alert follows a series of cartel-related disruptions, signaling intensified security concerns and prompting precautionary measures for residents and visitors.

The U.S. State Department issued a travel advisory urging U.S. citizens in affected areas to shelter in place due to ongoing security operations, road blockages, and criminal activity.

Tourists in Puerto Vallarta were advised to stay at their resort and not venture outside as the situation unfolded, with officials withholding immediate explanations for the caution.

Local officials described the situation as highly dangerous, with widespread roadblocks impacting traffic and mobility across the city and surrounding areas.
