A textile town on the Ave River in the Porto district, Santo Tirso sits in one of the consistently wettest parts of mainland Portugal, where the long Atlantic wet season keeps the surrounding countryside green through most of the year. The river can rise quickly after sustained heavy rain upstream. IPMA’s northern radar network provides continuous coverage of the Ave valley.
