Yellow heat warning issued for mainland Portugal
The Portuguese Institute for Sea and Atmosphere (Instituto Português do Mar e da Atmosfera or IPMA) has placed mainland Portugal under a yellow warning for high temperatures starting Monday. Meteorologists expect temperatures to reach 40ºC in some districts due to a hot air mass moving in from Spain, prompting authorities to advise caution.
A red warning is the highest alert level issued by Portugal's weather agency, the Portuguese Institute for the Sea and the Atmosphere (Instituto Português do Mar e da Atmosfera or IPMA), used when conditions pose a very high risk to life and property. Under a red warning authorities may close roads, suspend transport and advise people to avoid coastal and flood‑prone areas, so follow civil protection instructions during the Friday–Saturday storm period.
