On August 28, 2026, a thick blanket of fog caught many motorists off guard in Argentina, prompting a viral Twitter warning from user Alejandro Ramos. With visibility dropping below 50 meters in some areas, here's everything you need to know about driving safely through this weather phenomenon.

The morning of Friday, August 28, 2026 began with a dense layer of fog that took many drivers by surprise across Argentina. At 7:01 AM, Twitter user Alejandro Ramos posted a stark warning: #FOG... #CAUTION..., a message that quickly went viral among early-morning commuters.

What Is Fog and Why Is It Dangerous?

Fog is a meteorological phenomenon where tiny water droplets suspend in the air near the ground, reducing horizontal visibility to less than 1 kilometer. In extreme cases, visibility can drop below 50 meters, making driving extremely hazardous. According to Argentina's National Road Safety Agency, fog is one of the leading weather-related causes of traffic accidents, as it impairs reaction time and increases stopping distances.

Essential Tips for Driving in Fog

  • Slow down: Adjust your speed to visibility conditions. Recommended maximum speeds are 60 km/h on highways and 40 km/h in urban areas.
  • Use low beams and fog lights: High beams reflect off fog and worsen visibility. Turn on your front and rear fog lights if your vehicle has them.
  • Increase following distance: Keep at least double the usual distance from the vehicle ahead.
  • Avoid sudden braking: Use engine braking and signal turns well in advance to prevent chain collisions.
  • No overtaking: Passing in fog is extremely dangerous. Wait until visibility improves.
  • Follow road signs: Pay attention to traffic signals and weather warning signs.

Fog's Impact Beyond the Road

Fog doesn't just affect drivers—it also disrupts aviation and maritime navigation. Airports may experience flight delays or cancellations, while ports face reduced visibility for docking maneuvers. In cities, fog often leads to traffic congestion and public transport delays. To stay informed, check official forecasts from Argentina's National Meteorological Service before heading out.

A Call for Solidarity

Alejandro Ramos's tweet wasn't just a warning—it was an act of solidarity. Many social media users thanked him for the heads-up and shared their own fog experiences. “Thanks for the alert, I was just leaving and had no idea it was this thick,” one user commented. Prevention and information are key to avoiding accidents. If you must drive, do so with caution and respect traffic rules. Your life is worth more than a few minutes of delay.
