But the heavy rains and thunderstorms projection by the Met Office this week might rather be a risk. Scientists are caution that they might lead to flash flooding and are notlikely to renew dry soils. Here is why torrential rain might not be what our dry land requires right now. Flash flooding On top of 2 heatwaves and record-breaking temperaturelevels this summertime, lotsof parts of the UK haveactually seen far-below typical rains. This has efficiently baked the soils, leaving them dry and difficult with extremely low wetness levels, the UK Centre for Hydrology and Ecology states. If rain falls in big quantities and at high speed, as occur in thunderstorms, the soil cannot soakup the wetness. Instead it swimmingpools on the surfacearea. On sloped surfaceareas, that water quickly runs off, triggering flash flooding. The result is like putting water at high speed on to concrete, Dr Rob Thompson, a meteorologist at th
