# Heavy Rain Events in Argentina 2026 > Live situation record from CLSTR: https://clstr.news/situations/heavy-rain-events-in-argentina-2026 > Updated: 2026-08-05T11:18:24.000Z. Sources: 5. Developments: 2. In early August 2026, a series of heavy rainfalls swept across Argentina. On August 2, a broad precipitation front drenched the Pampas, delivering up to 120 mm in parts of Buenos Aires Province and significant totals in Santa Fe and Entre Ríos. The rain alleviated drought stress on wheat and barley fields, prompting discussion of a possible strengthening of the El Niño pattern, while also causing temporary road closures in rural areas. A few days later, on August 5, intense rain moved southward to the Alto Valle and Río Gallegos regions. The town of Roca recorded 10‑20 mm of rain with strong wind gusts, and Neuquén experienced gusts over 50 km/h. In Río Gallegos, about 20 mm fell over several days, a volume described as historic, raising concerns about combined meltwater and flood risk. Authorities continued monitoring the situation through the National Meteorological Service. Overall, the weather pattern shifted from providing much‑needed moisture for agriculture in the central Pampas to generating flood‑related warnings in southern provinces, illustrating the wide geographic impact of the August rain events. ## Timeline ### 2026-08-05: Heavy Rain Hits Argentina's Alto Valle and Río Gallegos Argentina's Alto Valle and Río Gallegos face historic rain, strong winds and flood risk as a polar air mass brings 10‑20 mm of precipitation and gusts up to 50 km/h. 2 sources. https://clstr.news/cluster/heavy-rain-hits-argentinas-alto-valle-and-ro-gallegos ### 2026-08-02: Heavy rains flood Argentina's Pampas, boosting winter crops Rainfall across Argentina's Pampas in late July and early August delivered up to 100 mm, easing drought‑stressed wheat and barley crops and sparking El Niño discussions. 3 sources. https://clstr.news/cluster/heavy-rains-flood-argentinas-pampas-boosting-winter-crops --- Cite as: Heavy Rain Events in Argentina 2026.
