Details

Hertfordshire and North London had a mixture of wet and dry days during January, with 126% of the long term average rainfall. The rainfall kept soils saturated through January, with soil moisture deficits ending the month at zero. There was a steady increase in baseflow in most of our rivers, with flashier peaks responding to the heavy rainfall, and flood alerts issued on 4 days. Groundwater levels rose in response to the seasonal recharge, although the contrast in the chalk bodies continued, with the Chilterns-East-Colne chalk suffering a slower recovery compared to the Lee Chalk.
