Extra police officers and protective barriers will be deployed to guard the area around Grenfell Tower during the Notting Hill Carnival.
Work in the tower will pause over the bank holiday weekend. A Met Police spokeswoman said:
At 3pm on Monday August 28 thousands of revellers along the carnival route will pause and observe a minute's silence to mark the tragedy, in which at least 80 people died.
A local volunteer said there would also be an increased cordon around the Lancaster West estate, with security passes for residents to get in and out of their homes.
Organisers are encouraging attendees to wear "green for Grenfell" in a display of "reverence and respect amidst the revelry".
