Amber wind warning as Storm Austen targets South West

Parts of south-west England are preparing for disruptive conditions on Friday after the Met Office issued an amber warning for wind as Storm Austen tracks across the region with gusts forecast to reach up to 80 mph in exposed areas.

Amber warning focuses on Cornwall, Scilly and west Devon

Publicly available information from the Met Office indicates that the amber wind warning covers the whole of Cornwall, the Isles of Scilly and parts of west Devon, including the Plymouth area. The warning is currently valid in the early hours of Friday 23 October 2026, generally from around 03:00 until late morning, coinciding with the period when Storm Austen is expected to be at its most intense over the far south west.

The amber alert is the second-highest level in the Met Office’s four-tier warning system and is issued when there is a high likelihood of significant impact. Guidance published with the warning highlights the potential for damaging gusts, difficult travel conditions and short-notice disruption to power and transport across the affected coastal and upland areas.

Forecast guidance suggests widespread gusts of 60 to 70 mph across much of Cornwall and the Isles of Scilly for a time, with the strongest winds expected along exposed Atlantic headlands where gusts could approach 80 mph. Inland parts of west Devon are also forecast to see very blustery conditions, although peak gusts there are currently projected to be slightly lower than on the immediate coast.

Heavy rain is expected to accompany the strongest winds during the early part of Friday, particularly as the main frontal band of Storm Austen moves east. Forecasters indicate that while rainfall totals in the far south west are not currently expected to reach warning criteria on their own, the combination of saturated surfaces, fallen leaves blocking drains and intense gusts could still lead to localised surface water issues and minor flooding on roads.

Storm Austen deepens as it approaches southern Britain

According to recent forecast discussions and analysis released by the Met Office, Storm Austen is a rapidly deepening Atlantic low-pressure system moving in from the west of Ireland toward the English Channel. Meteorologists describe the development as undergoing a phase of very rapid intensification, linked to a strong jet stream and marked temperature contrasts over the North Atlantic.

The latest outlook shows Austen sweeping across southern parts of the United Kingdom from late Thursday night into Friday morning, placing south-west England in the zone of strongest winds on the southern and western flank of the low. This track favours powerful onshore winds along the north and west coasts of Cornwall, the Isles of Scilly and parts of Devon, with additional exposure on high ground such as Bodmin Moor and Dartmoor.

The Met Office has also highlighted the broader context of an unsettled spell of autumn weather, with a series of Atlantic lows affecting the British Isles. Earlier this week, a yellow warning for wind had been in force for wider areas of southern England and south Wales before confidence in a more intense impact over the south west led to the amber upgrade for Friday.

As the low moves east during the day, winds are expected to ease gradually across Cornwall and Devon, although conditions will likely remain blustery into Friday afternoon. Forecasts for the weekend suggest further periods of rain and showers, but with the most dangerous phase of Austen’s winds confined to Friday’s morning hours in the far south west.

Travel disruption and coastal impacts expected

Travel operators and infrastructure managers across the region are monitoring the latest guidance, and publicly available statements indicate that short-notice changes to services are possible on Friday morning. Strong crosswinds, fallen branches and debris have the potential to affect road and rail corridors, particularly on exposed routes in Cornwall and west Devon.

Road users are being advised through public channels to allow extra time for journeys, especially on higher routes and coastal roads where sudden gusts can be hazardous to high-sided vehicles, motorcyclists and cyclists. Surface spray and standing water in heavier showers could further reduce visibility in the early part of the day.

Conditions at sea and along the coast are forecast to be particularly hazardous as the combination of strong onshore winds and large waves develops in the Celtic Sea and along the western Channel. Information available from maritime forecasters points to rough or very rough seas off the Cornish coast during the warning period, which may affect ferry links to and from the Isles of Scilly and small harbours exposed to the Atlantic swell.

Those planning coastal walks or visits to cliffs, breakwaters and beaches in Cornwall, the Isles of Scilly and north Devon on Friday morning are being urged by safety campaigns to reconsider their plans or exercise extreme caution. Even outside the heaviest showers, wave overtopping, sea spray and rapidly changing conditions can make popular viewpoints and harbour walls dangerous during strong wind events of this kind.

Yellow warnings extend risk beyond the core amber area

Alongside the focused amber alert, a broader yellow warning for wind remains in force across a wider swathe of south-west and southern England and parts of south Wales. Public warning maps show this larger area covering locations farther east along the English Channel, signalling that while the most severe gusts are expected in Cornwall and west Devon, disruptive conditions could still develop well beyond the amber zone.

Within the yellow area, gusts of 50 to 60 mph are widely expected, with the potential for occasional higher values in exposed coastal spots. While impacts at this level are generally less widespread than in an amber event, travel disruption, minor damage to buildings such as loose tiles or fences, and isolated power interruptions remain possible, particularly where local infrastructure is already stressed by previous unsettled weather.

The combination of the two warning levels reflects the varying degrees of confidence and impact across the region. The amber warning for south-west England indicates both a relatively high likelihood of strong winds and the expectation of more significant effects, while the surrounding yellow area captures uncertainty in Austen’s exact track and the possibility that the strongest core of winds could shift slightly before landfall.

Forecast updates issued on Wednesday 21 October emphasise that the track and intensity of Storm Austen will continue to be refined as new observational data and computer model runs become available. Travellers, residents and tourism businesses across Devon, Cornwall and neighbouring counties are being encouraged via public information channels to check for the latest warnings and local forecasts in the 24 hours leading up to the storm’s arrival.

Advice for residents and visitors in south-west England

For people living in or visiting Cornwall, the Isles of Scilly and west Devon, publicly available safety advice linked from the Met Office warns that preparation ahead of the warning period can help reduce the risk of damage and injury. Suggested steps typically include securing loose garden items, checking that outdoor furniture, trampolines and construction materials are tied down, and making sure that gutters and drains are as clear as possible to help manage heavy rainfall.

Homeowners and accommodation providers in coastal communities are also encouraged by national safety campaigns to review any flood or storm plans they have in place, particularly where properties are close to the shoreline or in exposed elevated locations. In guesthouses, hotels and self-catering properties, simple measures such as moving vehicles away from large trees, bringing in lightweight outdoor items and advising guests about the expected conditions can reduce potential problems during the peak of the storm.

For travellers arriving in the region by rail, road or air late on Thursday or early Friday, checking journey updates before setting out is being strongly recommended in transport advisories. Some operators may introduce speed restrictions on exposed rail lines, while road authorities can implement temporary closures if debris or fallen trees block key routes, especially across Cornwall where many main roads run through wooded or rural areas.

With Storm Austen expected to be the first significant windstorm of the current autumn season for south-west England, public information campaigns are stressing the importance of staying informed rather than alarmed. By following updated forecasts, heeding local travel and safety advice and allowing extra time for journeys, residents and visitors can better navigate the challenging conditions expected as the amber wind warning comes into force on Friday.
