As of Tuesday afternoon, the met agency hadn't issued any heat alerts for Mallorca but was anticipating that it probably will do for Thursday to Saturday.
Aemet says there is a mass of hot air moving in from the mainland and that temperatures are likely to rise progressively over the next few days - a high of 35C on Wednesday, then up to 37C on Thursday and Friday and 38/39C on Saturday. Yellow alerts are activated when temperatures of 36 to 38/39 are expected. Amber is for 39 to 41, and red for 42 and above.
As can be seen below, forecast highs vary across the island. The highest noted here is 37C in Binissalem on Saturday. At present, this high is expected to drop to 29C on Sunday. The met agency adds that there could be 'torrid' nights in some coastal areas - overnight temperatures no lower than 25C.
Other than some high temperatures, Wednesday is expected to be partly cloudy, especially in the morning.
