Intense rainfall during the morning of August 20, caused severe flooding across the Guadalajara Metropolitan Area (AMG), Jalisco, Mexico. The storm triggered flash floods in at least 15 neighborhoods and disrupted major transport corridors.

According to municipal reports, 51 homes sustained damage, particularly in Fraccionamiento Las Torres and Bosques de la Victoria. Local media reported the neighborhoods of Las Águilas, La Calma, Arboledas, Pinar de la Calma, and areas adjacent to Mercado de Abastos and Expo Guadalajara were among the most affected.

Floodwaters reached depths of up to 1.5 m (5 feet) in several underpasses, stranding dozens of vehicles. Emergency crews rescued people from submerged vehicles, including a mother and child near the intersection of Niños Héroes and Arcos.

Public transport services were severely disrupted. Light Rail Line 1 suspended operations between 18 de Marzo and Isla Raza stations due to track flooding. Local reporting noted interruptions to Mi Macro Calzada services along the Lázaro Cárdenas corridor.

According to municipal operations reports, 416 personnel were deployed to affected areas. Crews removed more than 11 tons of debris, cleared 1 620 m (5 315 feet) of roadways, and collected 105 m³ (3 710 ft³) of waste. Sixteen fallen-tree incidents were recorded, ten involving complete collapse.

Civil Protection issued advisories warning motorists and pedestrians to avoid underpasses, rushing water, and clogged drains, and urged cyclists and motorcyclists to wear visible safety gear and avoid flooded routes. Authorities also cautioned that additional rainfall is forecast.

The Guadalajara Metropolitan Area is highly prone to flooding, with 363 identified flood-prone points, of which 143 are classified as high priority by IMEPLAN. Urban expansion, inadequate drainage systems, encroachment on streams, and loss of natural vegetation have increased hydrological vulnerability in the region.

August is typically Guadalajara’s wettest month, with average precipitation of around 215 mm (8.5 inches).
