Flash droughts are likely to become increasingly common, say researchers

Droughts that intensify quickly used to be very rare but over the past 20 years they have become more frequent and intense. And because they come on suddenly, they are more difficult to prepare for.This year a flash drought dried out grasslands in Hawaii, intensifying the devastating wildfires that swept across the island of Maui.
