The yellow alert for high winds in Mallorca on Monday that Aemet first issued on Saturday has been extended to cover the whole island and for a longer period - 10am to midnight. The met agency's general warning is for gusts of 70 km/h but reaching 100 km/h on the peaks and capes. It should be stressed these are gusts and not sustained winds; 100 km/h is storm or whole gale force.

For the coasts there is a yellow alert for the same period with the exception of the north/northeast (from 12 noon rather than 10am); waves of three to four metres. This alert also applies to Tuesday morning - up to 8am (Tramuntana, north/northeast) and to noon for the south and east.

The wild weather is because of Storm Herminia. Aemet point out that when Atlantic fronts such as this reach the Balearics they normally don't produce much rain. Nevertheless, there could well be some isolated and occasional rain in Mallorca on Monday. The day will be mainly cloudy with some sunny periods.

On Tuesday, the wind is forecast to be from the northwest. So a fall in temperatures can be expected. Thunderstorms are currently predicted for Tuesday.

For the rest of the week, it will still be quite windy on Wednesday. It will be much calmer on Thursday, but a further bout of wind, this time from the northeast, is forecast for Friday and Saturday. A week with some showers and temperatures down to around normal for late January.
