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.
