tempo quente

This is the name IPMA gives to its heat warning: in the list of warning types, alongside wind, rain and thunderstorms, it appears as tempo quente. The warning is issued not for a single hot day but when high daytime temperatures persist for at least two days, and each district has its own threshold. The colour shows the severity: yellow, orange or red. On the IPMA website it is the row with a thermometer in the day-by-day strip.
