The most current models indicate Songda will likely graze the Philippines on Friday rather than making direct landfall.
However, according to U.S. Navy data, the storm is currently packing sustained winds of 213 kilometers per hour and generating waves of up to 35 feet -- and it's expected to strengthen as it nears the Philippines.
The storm has already brought heavy rains to the eastern shores of the Philippines.
Government officials are urging people to heed warnings and evacuate if necessary.
Domestic flights have been cancelled due to stormy weather, while nearly 4,000 people have been stranded in shut-down ports.
