AEMET NOTICE - Stormy weather in the Mediterranean areas

Information posted 1st December

From tomorrow, Monday 2nd, the stormy weather which has affected most of the country this weekend will reactivated as it moves towards the Mediterranean and joins the unstable flow of humid air coming from the east. This will cause large quantities of rainfall in Mediterranean areas accompanied by strong winds and rough seas.

Initially, the storm will move over the country towards the Gulf of Cadiz creating an isolated area of cold Low pressure (a Low at all levels of the atmosphere although less at ground level). Then, during Tuesday 3rd, it will move over the Mediterranean as a very defined storm lying at lower levels of the atmosphere and staying there until Thursday 5th.

This process will cause the air flow at all atmospheric levels to come from the east, carrying moisture from the sea. This moisture, although less significant than in Autumn when the sea is warmer, is still important as it rests within a mass of unstable air.

It is thought that this episode of adverse weather will start in the southeast of the country, and in the Strait and Alboran Sea, on Monday, bringing storms and downpours which will be heavy and persistent to the southern half of Valencia, Murcia and eastern Almeria. During Tuesday and Wednesday the stormy weather will extend over most Mediterranean areas of the country and the Balearics. The heaviest rainfall of this episode is expected in the southeast of the country.

Snowfall could also be significant in higher mountainous areas along the Mediterranean coast with the snowline coming down to around 1,200m.

Wind will also be an important consideration, with strong gusts which in coastal areas could reach 100kmh pr force 7 or 8 out to sea with waves over 4m high.

The instability will continue in the Mediterranean area during the following few days although with more localised downpours and lessening over this time. The rest of the mainland and the Canary Islands will not be affected although, from Thursday, a new Atlantic storm could affect the Canary Islands significantly.

AEMET issed an update at 13:30 on Mon 2nd - Lets hope it comes to nothing but the Google translation of the salient bits are as follows and may be worth winding in your awning if you are in that area:
It is expected that during Monday, the showers and storms locally strong or very strong and the most persistent rainfall affect coastal areas of the southern half of Valencia and northern Alicante, and with less probability and intensity to Murcia and eastern Almeria. During Tuesday and Wednesday the heavy or very strong and persistent showers and storms will extend to much of the Mediterranean area of the peninsula, Balearic Islands and Melilla. The greatest accumulations during the episode are expected, on Tuesday on the coast of Murcia and east of Almeria with values that can exceed 100 mm in 12 hours and on Wednesday the most affected areas will be the Valencian Community, Catalonia and the Balearic Islands. Early Thursday is still likely to persist rainfall in these areas, although tending to remit. The wind will be another important phenomenon with strong gusts in general, which on the coast can reach 100 km / h and in the sea the force 7 to 8, with waves that can exceed 4 m. The conditions that have resulted in the issuance of this special notice are expected to cease throughout Thursday 5.
