Mumbai today woke up to waterlogged roads and railway lines, flooding in low-lying areas, and water flowing into homes, shops and offices. After incessant rainfall through the night, the downpour intensified sharply early morning. Despite the high tide at 3.39 am not causing any damage, concerns grow as the rain shows no signs of abating. With another high tide expected at 4.09 pm today, authorities in Mumbai and surrounding areas are on alert.
