Several parts of India are currently witnessing torrential rains and consequent floods. IMD has predicted further devastation, issuing red, orange, and yellow alerts. If a green alert is issued, it means there might be a weather-related event but nothing worrisome. An orange alert indicates very bad weather conditions that may even disrupt road, rail, and air modes of transport. A red alert is issued when the weather conditions are extremely severe
