Overview

• Mexico’s weather service says Tropical Wave 35, a Gulf surface low and the monsoon trough will deliver intense, electrically active downpours Tuesday, with the heaviest totals in Chiapas and Veracruz and widespread storms from the southeast to the west and central states.
• Officials caution that the storms could produce rapid river rises, urban flooding, landslides, reduced visibility and pockets of hail, with rain chances persisting through Friday as the disturbance lingers.
• Despite the rain elsewhere, the northwest stays hot with 35–40 °C highs in Baja California, Sonora and neighboring states, and major Sonora cities near 38 °C with little rain expected.
• Sonora’s civil protection reports two Pacific low‑pressure areas under surveillance with about a 50% chance of tropical development within 48 hours, with no immediate threat indicated.
• Beyond Mexico, Peru remains under a Senamhi orange alert through today for mixed precipitation hazards across coastal and Andean regions, while Argentina’s SMN issues yellow alerts for northeastern thunderstorms and Patagonia winds that could exceed 90 km/h, and Catalonia sees a brief stabilization after Gabrielle with a late‑week shift possible.
