• Mexico’s Conagua/SMN forecast Tropical Wave No. 35 interacting with low pressure and the monsoon trough to deliver very strong to intense rains from Chiapas and Veracruz to the Yucatán Peninsula, alongside afternoon highs of 35–40 °C across wide areas.
• Sonora’s civil protection officials said two Pacific low‑pressure zones are under watch with roughly a 50% chance of tropical development within 48 hours, noting no immediate threat but urging close monitoring.
