At least two people have died after heavy rain caused a mudslide which engulfed the BR-376 motorway in Parana state. The whereabouts of around thirty people are unknown. Several vehicles are thought to have been buried under the rubble on the coastal road. Aerial pictures show lorries lying on their sides hanging perilously over the edge of the motorway. Social media footage showed motorists battling through muddy flood water before the landslide. Some people online have asked why the road was not closed earlier. Access to a major port for grains and sugar shipments has been cut off. About 80% of goods exported from Paranagua, the country's second-biggest port for grains and sugar, are delivered by truck. The state authority has declined to estimate the total losses.
