PEOPLE are being urged to stay at home and train services are being cancelled after the Met Office issued the highest level of alert for Storm Eunice.

The red weather warning – meaning high impact is very likely – comes due to the combination of high tides, strong winds and storm surge, a rare event for the UK.

The Met Office said there is a risk of “flying debris resulting in danger to life and damage to buildings and homes, with roofs blown off and power lines brought down”.

Amber warnings for wind, the second highest alert level, are in place across Sussex from 3am to 9pm today.

Winds of up to 100mph could batter the city in what is predicted to be the fiercest storm since 2013.

Southern Rail yesterday urged customers with Friday tickets to travel tomorrow instead, due to expected disruption and damage.

A spokesman said: We’re anticipating significant travel disruption on Friday. Please check your journey before travelling.

“High winds are forecast meaning 50mph speed restrictions will be in place across most of our network during the day.

“If you have a ticket dated February 18 and are able to travel on Saturday 19, your ticket will be accepted at no additional cost.”

A Network Rail spokesman said disruption was “inevitable” and has urged rail users not to travel.

The “do not travel” message was echoed by emergency services across the country, including East Sussex and West Sussex Fire and Rescue Services.

An East Sussex spokesman said: “With Storm Eunice on its way, we are urging everyone to avoid visiting exposed coastal areas for your own safety.

“If you have to travel by car, drive slowly and be aware of side winds. Be prepared and secure any loose objects outdoors.”

Brighton and Hove Buses said it was expecting to run a full service but was advising customers to check its website for updates.

Gatwick said passengers hoping to fly should expect disruption.

A spokesman for the airport said:” Be advised that due to Storm Eunice, there is the possibility for disruption to flights, and the shuttle service to North Terminal tomorrow, between approximately 10am and 4pm. Please arrive earlier if you are flying from Gatwick”

People living in Brighton are being urged to stay away from the seafront.

The city council has taken the decision to close the undercliff walk between Brighton Marina and Rottingdean due to the risk of powerful winds.

Council leader Phelim Mac Cafferty said: “Storm Eunice is expected to be extremely disruptive with an amber warning for Sussex. The city council will be providing storm updates.”

Brighton and Hove’s beaches can be "extremely dangerous" in stormy weather with violent waves coming from different directions, the council warned.

A spokesman from the RNLI said: “Respect the water. Check weather, tide and swell forecasts before you consider heading to the coast and avoid taking unnecessary risks by staying well back from stormy seas and breaking waves.”
