Yucatán authorities say severe heat wave unlikely as flood risk prompts urban drainage reforms

The State Civil Protection Coordination (Procivy) issued a final technical report stating that the forecast for July‑August 2026 does not anticipate a significant or destructive canícula in Yucatán. The agency, led by Hernán Hernández Rodríguez, noted that atmospheric conditions over the Atlantic, Caribbean and Gulf of Mexico lack evidence of prolonged extreme drought, and while local thunderstorms may continue, the El Niño influence is limited. The agency urged continued precautions such as avoiding sun exposure between 11:00‑16:00, staying hydrated, and keeping drains clear.

Climate experts highlighted the vulnerability of Mérida after the May 29, 2026 flood, attributing damage to the city’s karst limestone terrain, extensive paving and deforestation. They advocated for Sustainable Urban Drainage Systems, especially rain gardens, and a collaborative governance model involving science, the private sector and residents to improve storm‑water management and protect the underground aquifer.
