Theta, A "historic" Subtropical Storm, Is Approaching Spain: This Is

Theta, a “historic” subtropical storm, is approaching Spain: this is how it can affect us

2020 is the first hurricane season in history to show 29 named storms.

Theta's track according to the US National Hurricane Center.

The tormenta subtropical Theta has been formed about 1,500 km southwest of the Azores in the subtropical Atlantic, with direction towards Madeira and whose course puts it in the direction of the Canary Islands and the Iberian Peninsula, which has placed her under the surveillance of the Meteorology Statal Agency (Aemet).

It is, as explained Meteored, from a “historic” storm since, at the moment, no hurricane season has reached show 29 named storms. The current record was broken in 2005 when the Greek alphabet was used until reaching ‘Zeta’.

The Department of Meteorology model of Meteored ( for the next morning already foresees significant gusts of wind in this subtropical storm, about 2000 kilometers west of the Canary Islands, still far from our territory. Between tomorrow and Thursday it could reach winds close to 80 or 90 kilometers per hour., an intensity inherent to a tropical or subtropical storm. At once, will be approaching our country.

The system will reach a minimum pressure of 1002 hPa on Wednesday, and will then maintain these characteristics until reaching Madeira on Saturday. After, the cyclone could continue to circulate to the northeast, on its way to the Iberian Peninsula, or stay in the vicinity of the Canary archipelago. Everything will depend on the final intensity and the trajectory that the potential Theta traces, which according to some projections could become a category 1 hurricane at some point in its life.

“There is some uncertainty regarding the development and displacement of the system during this week towards the Peninsula or the Canary Islands. Currently, most models develop a subtropical system during the second half of the week, which would end up at the west of the Peninsula without affecting the Canary Islands“, Explain Francis Martin, meteorologist from Meteored.

“For this weekend, the most active center and radius of action of the tropical cyclone would be to the northwest and north of the Canary Islands, without directly affecting them,” the specialist expands his prediction. “Subsequently, a weakening of Theta is expected to be left over cooler waters and a hostile environment for its further development.”

For him Sunday November 15 the system would weaken and “would be absorbed a polar-type trough-front system coming from the northwest, but already very degraded off the Portuguese coast. His remains would pass through the peninsular west to the south of the British Isles next week. This scenario, Martín insists, is the “most probable and logical“.

“In principle, Theta is not expected to amplify, deepen and directly affect Spanish lands, and only collaterally could the northwestern areas of the Canary Islands and marine waters be somewhat altered“, he concludes. “The uncertainty for the weekend is high. In this sense, it will be necessary to follow the warnings of the NHC and AEMET to follow the possible final evolution of Theta and its remains”.

The system is organized with sustenance from a pocket of cold air aloft, starting at about 5,500 meters. This is typical of hybrid subtropical cyclones, which subsist thanks to this and to the energy provided by the relatively warm waters of the area. The “tropicals” rely solely on the warm, moist air available over the ocean.
