The National Meteorological Service (SMN) has issued several yellow alerts for heavy rain and strong storms, with possible hail, for this Monday, March 30, 2026. They cover various provinces, including Buenos Aires, within a framework of instability that also affects the Metropolitan Area. In total, eight provinces are under a yellow alert, with the most critical situation in Río Negro, which has an orange alert. Other affected provinces are Santa Cruz, Buenos Aires, Neuquén, La Pampa, Córdoba, La Rioja, and Catamarca. In the areas under alert, rains and storms of varying intensity are expected, some locally strong. These phenomena will be accompanied by abundant rainfall in short periods, which could cause temporary flooding in vulnerable areas. Additionally, frequent electrical activity, occasional hail, and wind gusts reaching up to 80 km/h are forecast. Accumulated precipitation values are estimated between 30 and 50 millimeters, although they could be exceeded in some areas. The areas under alert mainly include the north, northeast, and center of the province, where conditions could become more adverse during the morning and part of the afternoon on Monday, coinciding with the period of greatest storm intensity. Recommendations from the National Meteorological Service: Avoid going out during moments of greatest intensity. Do not take out the trash and keep drains and manholes clean. Unplug appliances and cut off the electricity supply if water enters the home. Stay away from doors and windows. Remove or secure objects that could be displaced by the wind. If outdoors, seek immediate shelter in a closed place like a house, building, or vehicle. The yellow level implies the possibility of meteorological phenomena with the capacity for damage and a risk of momentary interruptions in daily activities, so it is recommended to stay informed through official channels.
