Overview

• Argentina’s national meteorological service forecasts October–December temperatures above normal across most of the country, with about a 55% chance of hotter conditions centered on Córdoba and roughly 50% in adjacent central provinces.
• The seasonal outlook calls for generally near‑normal rainfall, with higher odds of above‑normal precipitation in northwest Argentina and potential deficits in Mesopotamia and parts of Patagonia.
• For Tuesday, yellow alerts are in effect for storms across Formosa, Misiones, Corrientes, Chaco, Santiago del Estero, Santa Fe and Salta, and for strong winds in Chubut and Santa Cruz with gusts that could exceed 90 km/h.
• Mexico’s weather agency expects heavy to intense rains linked to Tropical Wave 35, affecting states such as Chiapas and Veracruz most strongly, with additional impacts forecast for Oaxaca, Tabasco, Campeche, Yucatán, Quintana Roo and parts of the northwest and west.
• Despite widespread rainfall in the south and southeast, afternoon highs of 35–40 °C will persist in northwestern and Pacific states, and authorities are monitoring two Pacific low‑pressure areas with near‑50% odds of tropical development and warning of flood, landslide and road hazards.
