floods prevent car traffic in several parts of town, since the water can reach up to the top of tires and driving through puddles, without visualizing the ground, is very dangerous - it is not a good idea to assume large pools of water are safe to drive through since a number of hazards can be inside the water.

visitors should pay extra attention while crossing the streets in rain storms - when driving, visibility becomes severely impaired and breaking distances increase significantly - speeding cars could appear suddenly from around a corner, and drivers might not see pedestrians crossing.

rain storms are often accompanied by strong winds, and since the streets of rio de janeiro are filled with hundreds of tropical trees, branches fall with heavy rains - during rain storms, visitors should avoid walking outside in areas with lots of trees, such as jardim botânico or laranjeiras.

similar to any rainstorm around the globe, hillside neighborhoods are subject to falling rocks - 'morro do leme,' the small mountain at posto 1, occasionally features small rocks falling onto the walkway during heavy rains - the beachside road, connecting leblon to são conrado, is normally avoided at this time since there are potential dangers posed by two-way traffic and falling rocks.
