Overview
- An intense Zonda or Norte wind event overnight on July 17–18 struck San Salvador de Jujuy, toppling trees and power poles, damaging roofs and market stalls, injuring at least one person and forcing suspension of the Paseo de Invierno fair.
- The Servicio Meteorológico Nacional issued multiple yellow and orange alerts on July 18–19 for storms, heavy rain, strong winds, Zonda and cordillera snow that cover about 14–15 provinces and remain active into the current forecast period.
- Forecasts from SMN and meteorological analysts link the surge in instability to El Niño combined with strengthened upper‑ and low‑level jet streams and a blocking pattern that favor several days of short, intense rainfall, hail and violent gusts.
- Defensa Civil, fire brigades, police and utilities have been mobilized to clear debris, restore power and assist affected residents while officials urge people to stay indoors, secure loose objects and keep drains clear.
- Mexico’s weather service Conagua has issued parallel warnings for the monsoon in northern and western states, forecasting very intense localized rainfall, hail and flash‑flood risk that underscores a wider regional spike in hazardous weather.
