Meteorologists warn that a ‘monster’ storm is forming in the Atlantic

In the last 24 hours, meteorologists have changed their forecast since the formation of a “monster storm” to the northwest of the Canary Islands has become more evident. The European weather prediction model is forecasting heavy rain on all the islands, which are expected to be especially strong on La Palma, Tenerife, and Gran Canaria.

JJ González Alemán from AEMET said today that a "major storm" will affect the islands, as it passes between the Madeira and Canary Islands archipelagos.

Rain forecast for the next few days:
On Friday morning there will be rain in all of the islands, especially Lanzarote, Fuerteventura, Gran Canaria, and La Gomera, with between 3 and 5 millimetres (mm) of water accumulated in six hours.

On Friday afternoon the strongest showers will occur in the northeast of Tenerife (Anaga), the west of Lanzarote and Fuerteventura, and the north of La Palma and Gran Canaria. In these last two islands, the forecast for Friday night shows another 5mm accumulated rainfall in six hours.

On Saturday, the rain will be weaker in Lanzarote and Fuerteventura, but it will gain intensity in the rest of the archipelago, especially in Gran Canaria and La Palma, but also in the north and east coast of Tenerife, where they are forecast to reach between 5 and 10mm accumulated in six hours.

In the early hours of Sunday, Lanzarote and Fuerteventura will be the most affected by the rains, but as the day progresses, it will be in La Palma where the highest accumulated rainfall will be recorded, up to 40 mm in six hours.

However, La Gomera, the southwest coast of Tenerife, and the southwest of Gran Canaria will also have rain during the day.

From Tuesday next week, the rainfall will subside, although there is still plenty of time for the forecast to change.
