The video says at 2:40 "Before the storm hit, the Philippines Branch office began coordinating the evacuation and relief efforts.'We are preparing for the typhoon because the news said that we need to prepare, so I text everybody, every elder...' (- Rodnie Barcenas Circuit Overseer)."
So yes, the branch knew the typhoon was coming, they planned the evacuations (to kingdom halls?), instructed the CO's, and made sure all elders and congregations were informed of what to do.
Cedars covered this very well at the time. He calculates some figures:
"According to the 2014 Yearbook, the population of the Philippines is 97,701,745. And according to this new video (and official figures), Typhoon Haiyan claimed the lives of 6,200. That is a mortality rate of 0.0063% for the country.
By comparison, Watchtower claims to have 185,000 Witnesses in the Philippines. When we include all those presumed dead with the confirmed figures, this gives us a mortality rate of 0.024% among Witnesses for Typhoon Haiyan – nearly four times the previously stated figure."
