Overview
- Argentina’s weather service, which issued orange and yellow alerts Tuesday, warned Corrientes and eastern Chaco could see 60–120 mm of rain, hail and wind gusts near 90 km/h.
- In Buenos Aires and the surrounding metro area, forecasters expect daylong rain and southern gusts near 69 km/h, with La Plata under a local yellow alert for brief flooding rain and 60 km/h gusts.
- Mexico’s national outlook ties Tuesday’s showers to Cold Front No. 43 and a low‑pressure channel, bringing a “Norte” — a surge of cool northerly winds along the Gulf — while the west faces a heat wave with 40–45°C highs and freezing nights in high mountains.
- Mexico City expects late‑day showers with lightning, small hail and 50 km/h gusts, with the higher south and west boroughs, including Tlalpan and Cuajimalpa, most at risk for stronger cells.
- In Southern California, the National Weather Service projects an 80%+ chance of a cooler rain‑and‑wind system from Thursday through Sunday, with a few thunderstorms likely after last week’s unusual heat.
