Disaster relief agencies on the ground in the Philippines say it'll take a few days to measure the full scale of Typhoon Mangkhut's destruction.
The storm made landfall yesterday, bringing violent winds and pelting rain to the Philippines.
It's expected to head west into the South China Sea toward southern China - and could be the strongest storm to hit Hong Kong in sixty years.
Oxfam's Philippines director, Maria Rosario Felizco says the ferocity of the storm has been felt far and wide.
"Our assessment team reported the roof of the hotel they were staying blew off. "
She says these are only initial assessments, and it'll take a few days to see the full scale of the typhoon's impact.
