Steel drums echoed across west London as the Notting Hill Carnival commenced with its colorful J'Ouvert celebrations, a pre-dawn ritual where participants doused each other in neon and black paint. Thousands of revelers gathered for the historic Caribbean event, now in its 60th year.

Early arrivals at 6 a.m. engaged in the J'Ouvert tradition, throwing body paint and setting off smoke flares. Some participants donned horns and black paint to represent 'Jab Jab,' a costume originating from the Caribbean's 1838 abolition of slavery, symbolizing freedom from oppression. Images captured the vibrant scenes of people in glittering outfits dancing and playing steel drums, marking the start of the Families and Children's Day parade.

This year's carnival is expected to draw an estimated two million attendees, supported by a significant security presence. Approximately 7,000 Metropolitan Police officers and staff are on duty, alongside over 3,000 stewards, a number doubled from previous years. This increased staffing follows a £4.66 million grant announced in March, which transferred some crowd control responsibilities from the police to event organizers.

The large-scale operation is aimed at maintaining order, particularly in light of rising crime statistics and a high number of arrests at previous carnivals. Last year saw 528 arrests, including for assaults on officers, and incidents of stabbings. Concerns have been raised by some political figures regarding security, with calls for enhanced measures to prevent injuries.

In preparation for the event, some homeowners and businesses in Notting Hill boarded up properties, a measure taken in recent years due to instances of vandalism and public nuisance. The Metropolitan Police are employing advanced security tactics, including live facial recognition technology and number plate checks to identify wanted individuals. Additionally, there are targeted arrests of gang members and suspects in violence against women and girls cases. Measures such as knife arches and increased police patrols are also in place.

Organizers have implemented enhanced safety and crowd control measures, including an expanded control room and more CCTV cameras. Despite these efforts, security concerns persist, with critics highlighting the allocation of public funds for safety measures without clear targets and the potential impact of simultaneous cuts to police resources.

The weather forecast for the weekend anticipates a mix of sunshine and showers, with conditions potentially becoming wetter in the evenings. Monday is expected to be drier and brighter, though still subject to some showers. The carnival, which began in 1966, traditionally sees its main street events on Sunday and Monday, following a quieter opening day focused on competitions like the Panorama steelband competition.
