Overview

• Mexico’s SMN/Conagua projects strong to intense rainfall and thunderstorms today, citing the Mexican monsoon, tropical waves and low-pressure channels, and warns of hazards including flash floods, landslides, river rises, downed trees and reduced visibility.
• Very heavy to locally intense totals of 75–150 mm are forecast for Sonora (southeast), Chihuahua (southwest), Sinaloa (north and center), Puebla (east), Veracruz (center and south) and Oaxaca (north).
• In the Valley of Mexico, CDMX and Estado de México are expected to see strong to very strong evening and nighttime storms with lightning and possible hail, with CDMX near 22–24°C (13–15°C min) and Toluca near 19–21°C (8–10°C min).
• Accumulations of 50–75 mm are expected in Durango, Jalisco, Colima, Michoacán, Guerrero, Estado de México, Ciudad de México, Morelos, Chiapas, Campeche and Yucatán, with 25–50 mm in Baja California Sur, Nayarit, Tamaulipas, San Luis Potosí, Querétaro, Hidalgo, Tlaxcala, Tabasco and Quintana Roo.
• Argentina’s SMN posts yellow alerts for west winds in Tierra del Fuego (45–65 km/h, gusts up to 100 km/h) and persistent rain in southwest Santa Cruz (15–30 mm, possibly mixed with snow at elevation), as AMBA stays mostly dry today with higher rain chances into the weekend and Mendoza and Córdoba remain warm midweek before a late-week storm shift.
