Monday could bring some fog in areas early on, the forecast otherwise being for some sunny spells but also for rain and thunderstorms across much of Mallorca. There are yellow alerts for heavy rain (up to 30 litres per square metre) and thunderstorms in the north/northeast, east and interior from 12 noon to 6pm.
As with Sunday, it is possible these could be extended or upgraded. The initial yellow alert for rain on Sunday in the north/northeast was raised to amber, while an alert for rain in the Tramuntana was also issued. There was an absolute deluge in Formentor and Puerto Pollensa on Sunday as well as thunderstorms. Mid-afternoon, Aemet reported more than 1,000 lightning strikes in the area, many of them out at sea and including some that were cloud-to-cloud.

Tuesday should be a better day - far more sun and only some risk of rain - but Wednesday is currently looking pretty hopeless and Thursday not much better.
