For weeks the front rooms, church halls and community centres of W11 have been humming with the sound of sewing machines as the final sequins and feathers are sewn on to elaborate costumes in preparation for Europe's biggest street Carnival.
At noon that quiet hum will be replaced by the throbbing beat of soca, calypso and reggae as the 36th Notting Hill Carnival gets underway.
The event has come a long way since 1964 when the local Afro-Caribbean community took a small steel band procession onto the streets as a way of celebrating their culture. Carnival today is a major enterprise attracting big-name sponsors and thousands of tourists. More than two million people are expected to take to the streets of west London this weekend, making it second only to the Rio Carnival in size.
So what can first-timers expect from Carnival? Rum punch in plastic cups, cute kids in papier-maché bumble bee costumes, the smell of spicy jerk chicken hanging in the air, big crowds, gyrating dancers in sparkly thongs, long queues for the Portaloo and a pulsating soundtrack of music from around the world. And it's all free. Our guide shows you how to get the most from your day.
Quick guide to Carnival
1 Mas' Short for Masquerade, the costumed parades which form the backbone of Carnival. This year more than 50 mas' bands will pulsate and gyrate their way around the three-mile circular parade route, picking up followers along the way and hoping to impress the judges with their interpretation of a chosen theme: aliens, the Wild West and a celebration of black hair are just a few of the storylines to look out for this year. Music will be provided by live soca, calypso and steel bands. The parades take place between noon and 7pm on Sunday and Monday. The Sunday event is designated as a children's parade.
2 Static Sound Systems Originally frowned on by Carnival purists, the sound systems are now recognised as an important element of the Carnival experience and this year there are more than 50 systems to choose from each playing their own selection of soca, reggae, jazz, soul, hip-hop, house, garage and Latin. The best ones will attract big crowds. Just look for a huge stack of speakers and follow the noise.
3 Live stages BBC Radio 1 is hosting the biggest outdoor stage at Horniman's Pleasance with acts such as Wookie, Shola Ama and Jamelia appearing on Sunday and an all-day rap show broadcast live on Monday with a bill topped by De La Soul. In Powis Square the Resurrected Stage will feature live acts and DJs playing everything from samba to reggae and drum and bass.
4 Food stalls Hundreds of licensed street stalls will be selling delicious food including West Indian specialities such as jerk chicken, Jamaican patties and curries.
Five survival tips
1 Plan your travel carefully as some London Underground stations will be closed and bus routes diverted. Don't even think about driving to Notting Hill and allow extra time for train connections. It may be worth walking to a tube station further away from the action for a chance of even getting on a train.
2 The Carnival Route is three miles long, so comfortable footwear is vital.
3 Don't take valuables or expensive jewellery.
4 Agree on a rendez-vous point in case you lose your companions in the Carnival crush. If you should become separated from your kids there are lost and found children centres at Lancaster Road and outside the bus depot in Great Western Road.
5 Two of the best vantage points to watch the parade are the Kensal Green end of Ladbroke Grove and near the judging point halfway along Westbourne Grove. Those wanting to avoid the crush should head for Horniman's Pleasance or Powis Square where you can sit on the grass and watch the acts on the live stages.
