At the mouth of the Lima River in Portugal’s northernmost coastal district, Viana do Castelo sits in one of the wettest corners of the mainland, where Atlantic fronts arrive frequently and with force through autumn and winter. The historic riverside town occasionally sees the Lima run high after sustained heavy rain. IPMA’s northern radar network gives dense coverage of this exposed coastline.
