Torrential rains caused by a cold front moving across southeastern Spain flooded roads and towns on Tuesday, prompting authorities in the worst-hit areas to advise citizens to stay at home and avoid all non-essential travel. Spain's state weather agency AEMET declared a red alert in the eastern Valencia region and the second-highest level of alert in parts of Andalusia in the south, where a train derailed due to the heavy rainfall, although no one was injured.
