Following the news of the singer's tragic death yesterday (February 11), the Official Charts Company is expecting her music to re-enter the charts in the coming days.
Although the first verified sales reports for next week's tally won't be made until Tuesday (February 14), they have revealed that "sales are already surging".
Whitney Houston's Ultimate Collection album has soared to number one on iTunes, with her Greatest Hits in fourth position.
Such an impact would echo that of Michael Jackson's death in 2009 and Amy Winehouse's passing last year. In both cases, fans paid tribute by buying their respective singles and albums.
In summer 2009, six Jackson albums re-entered the chart, including a greatest hits at number one, while five singles landed back in the top 40 a week after his death.
Last year, Winehouse's albums took three places in the top 10, along with five singles in the top 40.
After Houston's first UK hit, 'Saving All My Love For You', topped the charts in 1985, she racked up a further four number one songs and 18 top 10 singles, as well as two number one albums
Her biggest hit was a cover of Dolly Parton's 'I Will Always Love You' from the film The Bodyguard, which became the biggest selling single of 1992 after occupying the spot for 10 weeks.
