The 2016–17 UK and Ireland windstorm season was the second instance of the United Kingdom's Met Office and Ireland's Met Éireann naming extratropical cyclones. Substantially less active than the previous season, the season succeeded the 2015–16 UK and Ireland windstorm season and preceded the 2017–18 UK and Ireland windstorm season.

In 2015, the Met Office and Met Éireann announced a pilot project to name storm warnings as part of the Name our Storms project for wind storms and asked the public for suggestions. The meteorological offices produced a full list of names for 2015–16, common to both the UK and Ireland. A new list of names was released on 19 September for the 2016–17 season. Names in the UK will be based on the National Severe Weather Warning Service, when a storm is assessed to have the potential for an amber 'be prepared' or red 'take action' warning.

Comparison of strongest gusts associated with each storm in the UK and Ireland.

Storm Angus was named on 19 November, with southern and southeast England, especially along the Channel coast expected to be the greatest affected areas as the storm moves northeast on 20 November. The storm was known as "Nannette" in France, Germany, Belgium and the Netherlands. Guernsey, in the Channel Islands, were hit with hurricane-force winds with the highest wind gusts since its 1990 record.

The south-west of England was affected with over 1,000 power outages, mostly in Devon. Residents were evacuated due to flooding near South Molton, Devon. Further flooding was reported in Braunton, Bradiford, Devon, and East Bar, Swanage, Dorset. The high winds affected train service in the south-east, ferry crossing at the Port of Dover and the Brighton 10k run.

The National Grid launched an investigation whether a ship's anchor damaged four of the eight cables of the Cross Channel high voltage interconnector during storm Angus, which would leave it only able to operate at half of its capacity until February 2017.
