She said about 600 participants in full fancy dress were expected to take part in the parade on Friday evening.

"This is their opportunity to show off on an international stage."

What's the weather going to be like for Halloween in Derry?

According to BBC News NI weather presenter Barra Best, unsettled and cold weather is typical at Halloween.

It will be a "mixed start" to the festivities, he said, adding Tuesday will see scattered showers.

"But it's an improving picture on Wednesday as drier weather develops," Barra said.

"That will be short lived with very windy and wet weather expected from the Atlantic on Thursday.

"However, for the big day on Friday the weather is set to improve. Although still quite windy and with the odd shower, it looks set to be much drier than Thursday."

Why is Halloween so big in Derry?

Pumpkin carving was originally turnip carving across the island of Ireland

Halloween's roots can be found in the ancient Celtic festival of Samhain (pronounced "Sow-in") marking the end of harvest time.

It was believed to be the time when the veil between the living and the dead was at its thinnest and spirits roamed the earth.

Organisers of this year's celebrations say the streets of Derry will be taken over by a cast of mythical and mysterious characters bringing Samhain to life.

While Samhain may now inspire events in Derry, there's a more modern tale told of how Derry became a Halloween hotspot.

It all started in a city centre pub in the 1980s when a canny publican wanted punters to come ready to party in fancy dress on Halloween.

That night, the bar – and the street - inadvertently filled with cavemen, more than one incredible Hulk, a few Ronald Reagans and a Margaret Thatcher or two.

And the rest, to coin a phrase, is history - official civic celebrations started in 1986.

Now, tourism bosses say the Halloween in Derry is a "a standout celebration".

Coverage of the Halloween Festival

BBC News NI will capture all the magic of Halloween night with a dedicated online live page, bringing viewers right to the heart of the celebrations.

You can follow all the sights and sounds of the spectacular parade and stay tuned for the dazzling firework finale over the River Foyle.

The festivities don't stop there, with a number of special live radio programmes keeping the spirit of the festival alive throughout the week.

On Friday, BBC Radio Ulster presenter Connor Phillips and BBC Radio Foyle's The Mark Patterson Show will be broadcasting live from Guildhall Square, soaking up the atmosphere and chatting to some of the people who make this event so special.
