Parts of India and South Asian countries, as well as China and Japan, have been hit with unusually heavy monsoon rainfall and flooding.
This has caused major disruption, displacement and loss of life.
More than 200mm of rainfall could fall in 24 hours in some mountainous regions of Bhutan/Bangladesh, Northeast India, Myanmar and Nepal according to the South East Asia Flash Flood Forecast System.
Additional similar amounts could be possible for the next 4-5 days. Authorities in China are also warning of more rains.
The India Meteorological Department has issued top-level red warnings for heavy rainfall for many north and northeastern Indian sub-divisions for the next 4 days, mainly Assam & Mehghalaya, Arunachal Pradesh, Bihar, and East and West Uttar Pradesh, valid through 12 May.
Many areas in central and north/northeast India have seen more than 150mm above-average monsoon rains so far this year. Tens of thousands of people have been forced out of their homes in the Assam region of India, and there has been coastal flooding in the state of Gujarat.
