Can a hurricane like ‘Fiona’ condition the weather situation in the Iberian Peninsula without even being close? In reality, yes, like any large weather system that violently erupts in the polar jet and deforms the mid-latitudes circulation.

After causing severe damage in Puerto Rico and the Dominican Republic, ‘Fiona’ became a ‘major hurricane’, which is what the US National Hurricane Center calls hurricanes that reach Category 3 or higher.

Its winds are over 180 km/h and forecasts indicate that they will continue to increase until they reach or exceed 220 km/h, which would make it a category 4 hurricane. which, for the time being, will not pose a direct threat to the population, although it could affect Bermuda in the coming days.

After reaching this intensity, ‘Fiona’ will continue to move north and begin its extratropicalization, ie, its transformation into a mid-latitudes storm. However, this process will be particularly violent in the case of ‘Fiona’: it will hardly lose intensity, maintaining hurricane-force winds over a considerably large area.

The passage of ‘Fiona’ will facilitate the appearance of a very robust anticyclone over the Central Atlantic, causing a major planetary depression to grow over Europe.

This depression will affect practically the entire continent next week and will move to the Iberian Peninsula, where an unstable period can be expected in which significant thunderstorms are likely to develop and, in addition, temperatures will decrease compared to previous days. .
