IPMA is the Portuguese Institute of the Sea and Atmosphere (Instituto Português do Mar e da Atmosfera), the national agency for weather, marine forecasts and climate monitoring. Residents should watch its forecasts and warnings during storms, heatwaves or cold snaps because IPMA issues official advisories used by services, transport operators and local authorities.
