Overview

• Argentina’s meteorological service placed the City of Buenos Aires and parts of the province under an orange alert for Tuesday as a deepening low brings heavy rain, thunderstorms, strong gusts and possible hail across the AMBA.
• Forecasts point to the heaviest precipitation on Tuesday and a turn to stronger winds on Wednesday, with Rosario expecting 50–100 mm of rain and gusts up to 80–90 km/h under successive orange and yellow alerts.
• Separate Zonda wind alerts remain active for Salta and Jujuy, with 35–50 km/h winds and gusts above 75 km/h in lowlands and up to 120 km/h over higher terrain during defined Tuesday time windows.
• Mexico’s weather agency projects very strong to locally intense rainfall in Chiapas of 75–150 mm from Tuesday through Thursday, alongside widespread heavy precipitation, thunderstorms and strong winds across multiple states through Friday.
• Authorities advised securing loose objects, avoiding shelter near trees and power lines, preparing emergency kits, following official updates and, in northwest Argentina, avoiding open burns due to elevated fire danger.
