Rainy Season in Mérida Makes Unsafe Buildings All the More Dangerous

Store closure highlights broader safety concerns as Yucatán's wet season intensifies building maintenance challenges

Mérida’s Civil Protection authorities closed the Milano clothing store on Calle 65 on Tuesday following a typical rainy-season downpour that exposed serious structural deficiencies in the building’s roof and drainage systems.

The store, between Calles 58 and 60 in the heart of the historic center, showed multiple signs of water damage after Tuesday’s rainfall. Inspectors found excessive humidity, wall seepage from a deteriorated cornice, and blocked drainage ducts that caused water accumulation.

Crumbling structures in Centro have been an ongoing safety concern. In 2021, a crafts store partially collapsed. Two years earlier, a cantina’s walls collapsed, killing three in Progreso. And throughout Yucatán, at least 30 old churches are at risk of collapse, officials said.

The ground floor suffered from falling drywall panels due to water infiltration. Upstairs, sections of the ceiling finish detached, accompanied by extensive humidity and leaking. The building lacked updated Civil Protection protocols, leaving emergency procedures unclear.

“We cannot guarantee the safety of employees and customers,” said Civil Protection officials, who suspended operations until all deficiencies are corrected.

The Milano store’s closure was part of the city’s “Aguas con tu Techo” (Watch Your Roof) prevention campaign, launched this month as Yucatán’s rainy season reaches full intensity.

Widespread Risk Assessment

The incident reflects broader concerns about aging infrastructure throughout Mérida’s Centro Histórico, where buildings dating back centuries face mounting pressure from increasingly intense precipitation patterns.

Zazil Canto Ureña, president of the Patronato para la Conservación del Centro Histórico de Mérida, said her organization conducted outreach before the current rainy season, encouraging residents to inspect roofs and perform necessary maintenance.

“Citizens understand the importance of their properties.” Canto Ureña explained. “They know about the investment required to purchase materials and maintain these old buildings to avoid accidents.”

In 2024, municipal authorities identified 300 properties classified as risk sites at various levels throughout the historic center. The number fluctuates constantly as conditions change, making comprehensive tracking challenging.

Canto Ureña noted that residents frequently approach the patronato seeking guidance on building maintenance and available assistance programs. The city offers a facade rescue program where property owners provide materials while the municipality supplies labor.

Climate Pressures Mount

Mexico’s rainy season, running roughly from May through October, brings particular challenges to flat-roofed buildings common throughout the region. Most homes feature flat roofs that require regular maintenance to prevent water pooling and structural damage.

Recent weather patterns have intensified these challenges. In 2020, storms Gamma and Delta set new rainfall records in Yucatán, damaging both modern and ancient structures across the region. The damage extended to archaeological sites, with 20 to 25 historic buildings in archaeological zones suffering harm.

Colonial-era religious buildings face particular vulnerability. At least 40 churches throughout Yucatán require immediate structural attention, with 10 having suffered partial ceiling collapses during recent rainy seasons.

Prevention Efforts Intensify

Municipal Civil Protection authorities are emphasizing preventive maintenance as the most effective approach to avoid emergency closures and potential accidents.

Current recommendations include removing accumulated debris and leaves, pruning tree branches over roofs, inspecting marquees and cornices, eliminating parasitic vegetation, and sealing cracks to prevent water infiltration.

The patronato’s offices on Calle 46 between 63 and 65 provide free facade assessments, including detailed observations and corrections. Staff assist property owners navigate municipal programs and documentation requirements.

Weather experts note that Mexico’s rainy season typically produces short, intense afternoon storms rather than all-day precipitation, though the concentrated nature of these downpours can overwhelm drainage systems and expose structural weaknesses quickly.

For international visitors and residents familiar with different measurement systems, Yucatán typically receives between 600 and 1,000 millimeters (23.6 to 39.4 inches) annually, with most precipitation concentrated during the wet months.

The Milano store closure underscores the ongoing challenge of maintaining centuries-old architecture in a tropical climate, where intense weather events continue testing both historical and modern construction methods.
