Torrents of floodwaters and mudslides dragged cars and houses through the streets of the city Tuesday during the most intense rainfall in decades. One video showed two buses sinking into a swollen river as its passengers clambered out the windows, scrambling for safety. Some didn’t make it to the banks and were washed away, out of sight. Survivors dug through the ruined landscape to find loved ones even as more landslides appeared likely on the city's slopes. A small slide Thursday prompted an evacuation but didn't cause injuries. As evening came, heavy showers returned to the region, sparking renewed concern among residents and rescue workers. Authorities insisted those living in at-risk areas should evacuate.
