Weather tracker: monsoon rains cause deadly floods in Pakistan and India

More than 300 dead after downpours in mountainous regions and several killed in Indian city of Mumbai

Heavy monsoon rains have continued to pummel the Indian subcontinent over the past week, bringing devastating flooding and landslides and leaving hundreds of people dead in what has already been one of the deadliest monsoon seasons in recent years.

Moist air surging inland from the Bay of Bengal and the Arabian Sea was driven into Pakistan and north-west India late last week by strong southwesterly monsoon winds. Combined with developing areas of low pressure, this triggered a succession of torrential downpours.
