Mexico Flags Pacific Low With Heavy Rain Threat as Argentina Warns of Weekend Storms

Official forecasts call for coastal gusts and intense downpours in western and southern Mexico and warn of Zonda winds and severe thunderstorms across central Argentina, while Galicia faces mostly cloudy, low‑impact conditions.

Overview

  • Mexico’s SMN/CONAGUA locates a low‑pressure area south of Michoacán and Colima with potential for tropical development, forecasting intense rains in Guerrero and Oaxaca and 60–70 km/h coastal gusts from Colima to the Tehuantepec region.
  • Additional troughs and moisture channels are set to drive very heavy rainfall over the Gulf and southeast, with strong storms also projected for the Valley of Mexico including Mexico City, Estado de México and Morelos.
  • A new cold front approaching northwest Mexico brings increased winds there, yet Monterrey’s Friday outlook remains mostly clear and warm with a high near 31°C and minimal rain chances.
  • Argentina’s SMN issues orange and yellow alerts for Saturday–Sunday, warning of severe storms over northwest Buenos Aires and parts of Santa Fe and Córdoba with 40–80 mm of rain, frequent lightning, hail and gusts that may exceed 90 km/h.
  • Widespread yellow alerts also cover strong winds across 11 Argentine provinces and Zonda in sectors of Mendoza and San Juan, while AMBA is expected to see storms develop Saturday night and persist into Sunday.
