Severe Storms Threaten Parts of Northern Argentina, Yellow Alert Issued
A yellow weather alert has been issued for several provinces in northern Argentina as a system bringing isolated, potentially severe thunderstorms moves across the region. The Servicio Meteorológico Nacional (SMN), Argentina’s national meteorological service, warns of possible heavy rainfall, strong winds, and hail, posing a risk to residents and infrastructure. The affected areas include Jujuy, Salta, Tucumán, Catamarca, Mendoza, and San Luis, with conditions expected to deteriorate throughout Saturday, February 21, 2026.
The alert, signifying a potential for dangerous weather, highlights the importance of preparedness and caution for those living in and traveling through the impacted provinces. While not immediately life-threatening, the combination of intense rainfall, strong winds, and potential hail can disrupt daily life, damage property, and create hazardous travel conditions. The SMN is urging residents to stay informed and take necessary precautions as the storm system progresses. Understanding the specific risks associated with these types of storms – including flash flooding and wind damage – is crucial for ensuring safety.
The primary concern centers around the potential for localized heavy rainfall, with accumulations forecast between 25 and 50 millimeters across the alert area. However, Salta province is expected to experience particularly high rainfall totals, potentially reaching between 40 and 70 millimeters. This increased precipitation raises the risk of flash flooding, especially in low-lying areas and near waterways. In the higher elevations of the puna region, precipitation is likely to fall as snow and/or hail, adding another layer of complexity to the weather situation. The combination of these factors necessitates a heightened state of awareness and proactive safety measures.
Alert Details and Timeline
The yellow alert indicates that the affected provinces will experience isolated thunderstorms, some of which may be strong or even severe. These storms are anticipated to be accompanied by intense electrical activity, heavy downpours in short periods, and wind gusts that could reach up to 80 kilometers per hour. The alert is currently in effect throughout the night across all provinces, with conditions in Mendoza expected to begin impacting the region from the afternoon and continuing into the night. The Servicio Meteorológico Nacional provides ongoing updates and detailed forecasts on its website.

Safety Recommendations from the SMN
The SMN has issued a series of recommendations for residents in the affected areas to minimize risk during the storm. These include avoiding outdoor activities, clearing drainage ditches and gutters to prevent flooding, and disconnecting electrical appliances if water enters buildings. This proves also advised to close and secure doors and windows, and to secure or remove any objects that could be carried away by strong winds. Individuals caught outdoors during the storm should seek immediate shelter in a sturdy building, house, or vehicle. These preventative measures are crucial for protecting lives and property during severe weather events.
Specifically, the SMN advises the following:
- Avoid going outside.
- Do not dispose of trash and clean drains and sewers.
- Disconnect electrical appliances and cut off the power supply if water enters.
- Close and stay away from doors and windows.
- Remove or secure objects that could be carried away by the wind.
- If you are outdoors, seek immediate shelter in a building, house, or closed vehicle.
Understanding Yellow Alerts and Regional Impacts
A yellow alert, as defined by the SMN, signifies that meteorological conditions could potentially pose a moderate risk. While not as severe as a red or orange alert, a yellow alert requires vigilance and preparedness. The current alert covers a significant portion of northwestern Argentina, impacting provinces with diverse terrains, from the mountainous regions of Jujuy and Salta to the more temperate areas of Tucumán and Catamarca. Mendoza, located further south, is expected to experience the effects of the storm later in the day. The varied geography of the region means that the specific impacts of the storm – such as the risk of flooding or landslides – will differ from province to province.
The potential for strong winds also presents a hazard, particularly in open areas and at higher elevations. Gusts of up to 80 kilometers per hour can cause damage to trees, power lines, and infrastructure. The combination of strong winds and heavy rainfall can also create hazardous driving conditions, with reduced visibility and increased risk of hydroplaning. Travelers in the affected areas are advised to exercise caution and monitor road conditions before embarking on journeys.
The city of Salta, a major urban center in the region, is particularly vulnerable due to its location and population density. Local authorities are preparing for potential flooding and are working to ensure that drainage systems are clear and functioning effectively. Residents are encouraged to stay informed about the latest weather updates and to follow the guidance of emergency officials. The potential for significant rainfall in Salta province underscores the need for proactive measures to mitigate the risk of damage and disruption.
Looking ahead, the SMN will continue to monitor the storm system and provide updated forecasts and alerts as conditions evolve. Residents in the affected provinces are encouraged to stay tuned to official sources of information, including the SMN website and local news outlets. Preparedness and vigilance are key to minimizing the impact of this severe weather event. The next official update from the SMN is expected on Sunday, February 22, 2026, providing a more detailed assessment of the storm’s trajectory and potential impacts.
