Storms Threaten Buenos Aires After Period of Mild Temperatures
Buenos Aires is bracing for potentially severe thunderstorms after experiencing a spell of relatively mild weather. Whereas the city enjoyed sunny conditions and rising temperatures earlier in the week, forecasts now indicate a shift towards more unsettled conditions, with heavy rainfall expected to begin imminently. The Servicio Meteorológico Nacional (SMN), Argentina’s national meteorological service, has issued alerts for potential flooding and strong winds, urging residents to take precautions.
The change in weather comes after a period where temperatures climbed steadily, reaching 28°C (82°F) on Thursday, February 19th, with a ‘feels like’ temperature of 19°C (66°F). Winds were initially from the southwest at 7-16 km/h. However, the forecast for the coming days paints a different picture. The SMN warns of increasing cloud cover and a higher probability of precipitation, particularly on Saturday. This shift follows a period of lower temperatures earlier in the week, setting the stage for a potentially volatile weekend.
Current Conditions and Short-Term Forecast
As of 8:00 AM local time on Thursday, February 19th, conditions in Buenos Aires were sunny with a temperature of 19°C (66°F). The ‘feels like’ temperature was also 19°C (66°F), with southwest winds blowing at 7-16 km/h. The UV index was low, requiring a minimal sun protection factor (FPS) of 2. Humidity stood at 63%, with a dew point of 12°C (54°F) and visibility was excellent at 18 km. The atmospheric pressure was 1017 hPa, and the snow line was at 4300 meters.
Looking ahead to the rest of Thursday, the forecast predicts intervals of cloudiness. Friday, February 20th, is expected to be warmer, with a high of 30°C (86°F) and a low of 14°C (57°F), accompanied by winds of 15-30 km/h. Saturday, February 21st, will see similar temperatures – a high of 30°C (86°F) and a low of 19°C (66°F) – with winds between 13-27 km/h. Sunday, February 22nd, is predicted to be slightly cooler, with a high of 29°C (84°F) and a low of 15°C (59°F), and winds of 8-21 km/h. The forecast extends into next week, with temperatures remaining relatively high, peaking at 31°C (88°F) on Tuesday, February 24th.
Weekend Outlook: From Warm to Wet
The anticipated shift in weather patterns is particularly concerning for the weekend. While Friday is expected to remain warm and relatively dry, the SMN has alerted the public to the possibility of showers on Saturday. Sunday is currently forecast as unstable, with a high likelihood of more significant rainfall and potentially strong winds. This contrasts with earlier reports suggesting a continuation of excellent weather into the weekend. Diario Popular reported on February 19th that Sunday would have good conditions and temperatures between 22°C and 31°C (72°F and 88°F).
The discrepancy between the current forecast and earlier predictions highlights the dynamic nature of weather systems and the importance of staying updated with the latest information from official sources. The SMN’s alerts emphasize the demand for preparedness, particularly for residents in low-lying areas prone to flooding. The potential for strong winds also raises concerns about possible damage to infrastructure and trees.
Impact and Preparedness
The approaching storms are expected to impact a wide range of activities in the Buenos Aires Metropolitan Area (AMBA). Outdoor events may be canceled or postponed, and transportation could be disrupted due to flooding or strong winds. The SMN advises residents to secure loose objects, avoid unnecessary travel during periods of heavy rainfall, and stay informed about the latest weather updates.
The potential for flooding is a particular concern, as the AMBA has experienced significant rainfall events in recent years that have overwhelmed drainage systems. Local authorities are working to clear drains and prepare for potential emergencies, but residents are urged to take their own precautions, such as ensuring that gutters are clear and that valuables are protected from water damage. The approaching cold front, following the warm spell, could also exacerbate the impact of the storms, potentially leading to more severe weather conditions.
The forecast also comes after a period of low temperatures, as reported by Urgente24 on August 16, 2025, which indicated a cold and cloudy weekend was anticipated. This demonstrates the fluctuating weather patterns in the region.
Longer-Term Outlook and Regional Variations
Beyond the immediate weekend forecast, the outlook for the coming week suggests continued warm temperatures, with highs consistently above 30°C (86°F). However, the possibility of further rainfall remains, and the SMN will continue to monitor the situation closely. Regional variations in weather conditions are also expected, with some areas of the AMBA potentially experiencing more severe storms than others.
The current weather patterns are consistent with broader climate trends, which indicate an increase in the frequency and intensity of extreme weather events. While This proves difficult to attribute any single weather event to climate change, scientists agree that a warming planet is contributing to more volatile weather patterns around the world. This underscores the importance of investing in climate resilience measures and reducing greenhouse gas emissions.
