Dozens of people have been injured by gusts of wind. Officials say more than 229,000 homes in Okinawa Prefecture and about 67,000 homes in Kagoshima Prefecture are without power. Experts are warning against any outdoor activity. They say the typhoon could cause old buildings to collapse, and damage steel-framed structures. They are also urging people to be careful of falling electrical utility poles and even concrete walls. Moving trucks could be blown over.
