Hurricane-force winds have struck central and northern Portugal, leaving 300,000 residences without having power.

The remnants of Hurricane Leslie swept in overnight on Saturday, with winds gusting up to 176km/h (109mph).

Civil defence officials stated 27 individuals suffered minor injuries, with localised flooding, hundreds of trees uprooted and a number of flights cancelled.

The storm, 1 of the most strong to ever hit the country, is now passing over northern Spain.

  • Is climate alter creating hurricanes worse?

The worst-impacted locations in Portugal have been around the capital, Lisbon, and in the districts of Coimbra and Leiria. Aveiro, Viseu and Porto in the north also suffered damage.

About 1,000 trees have been uprooted, officials say. The primary A1 motorway was amongst the roads temporarily blocked.

Some 1,900 incidents were reported to emergency services, even though civil defence commander Luis Belo Costa mentioned “the greatest danger has passed”.

Hundreds of people remained in an arts centre in Figueira da Foz after a concert because of the high winds.

A resident of the town told SIC television: “I have never ever noticed anything like it, The town seemed to be in a state of war, with vehicles smashed by fallen trees. People had been quite worried.”

The roof blew off a stadium hosting the European final of the women’s roller hockey competitors, halting the event, AFP news agency reported.

It is rare for an Atlantic hurricane to attain the Iberian peninsula, with only 5 such events recorded.

Hurricane Leslie had formed on 23 September but was downgraded to a tropical storm before it produced landfall. Even so, it retained gusts of hurricane strength.

The Spanish Meteorological Agency (Amet) stated Leslie was moving north-east by means of the peninsula.

Gusts of nearly 100km/h have been recorded close to the city of Zamora early on Sunday, but winds have now lessened.

Amet said that on Sunday morning huge places of Asturias, Castille and Le&oacuten and Cantabria would be affected, with north-eastern places hit in the afternoon.

Four departments in southern France have also been put on alert for storms and flooding.

Hurricanes develop from thunderstorms, fuelled by warm, moist air as they cross sub-tropical waters.
Warm air rises into the storm.

Air swirls in to fill the low stress in the storm, sucking air in and upwards, reinforcing the low pressure.
