Swansea sits in Wales, one of the wettest parts of the United Kingdom, where mountainous terrain wrings substantial rainfall out of Atlantic weather systems arriving from the southwest.
On Wales’s south coast, the city’s surrounding valleys can funnel heavy rain into the Tawe River quickly. The combination of steep valleys and high rainfall totals makes parts of Wales prone to fast river rises, and radar tracking helps distinguish a passing shower from the kind of sustained rain that leads to river flooding.
