NASA satellite imagery has captured and analysed extreme rainfall in Haiti and the Dominican Republic in the last week or so.
The US space agency estimates that over 300mm (11.8 inches) of rain fell over large areas of the eastern Dominican Republic during the the week from 2 May to 9 May, 2016.
The heavy rains in the Dominican Republic have resulted in rivers overflowing and urban flooding, including in the capital city of Santo Domingo. During the last three weeks, Haiti has seen the equivalent of half its usual yearly precipitation, even though the hurricane season which begins 1 June and runs through 30 November has not yet begun.
Since 2 May flooding has killed at least four people in Haiti and five people in the Dominican Republic and displaced thousands of others.
Data from NASA’s Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the amount of rain that fell over this area and the results are shown in the image above.
The Carribean region had been suffering from drought conditions for much of 2015 leading to crop losses. But in late December 2015 the rains began and produced flooding in January 2016, in late February and into March. This latest rainfall means that Haiti and the Dominican Republic have almost erased the deficit of water caused by the drought.
