Europe is Bracing For (Another) Devastating Drought

After unusually low amounts of rain and snow this winter, the continent faces a severe water shortage. From a report: What happens during the next few months will really matter. Abundant rainfall could ease the situation and stave off the worst-case scenario. But Europe needs a lot. "We're talking about a sea, a sea's worth of water," says Hannah Cloke at the University of Reading in the UK. In terms of volume, hundreds of millions of cubic liters of rain would have to fall across the continent to fill the deficit, she estimates. It would have to amount to higher-than-average rainfall for France and certain other places, including parts of the UK. The chances of that are, unfortunately, not high. The UK's weather agency, the Met Office, estimates there's a 10 percent chance of a wetter-than-average March, April, and May. Conversely, there's a 30 percent chance that this period will be drier than average -- and that is 1.5 times the normal chance at this time of year. The Met Office stresses that this is a "broad outlook," and there might still be patches of very wet weather even if it remains dry overall. Any rain that does fall also has to fall in the right way and in the right places. "There's always this chance that if we do get it all in two days, we see some very serious floods," says Cloke. "What we want is to see sustained, reasonably gentle rain over the next few months." Another important factor is how hot it gets this summer, says Cammalleri. Heat waves push up water consumption and increase evaporation rates. He indicates that European forecasts do not suggest that temperatures will be quite as blisteringly hot as last year -- though there is some uncertainty there too.
