While the National Hurricane Center (NHC) warned that Hurricane Florence is set to make impact on the coastal areas of North and SC on September 14, Super Typhoon Mangkhut is larger and has an extra day or two before hitting a major body of land, possibly Luzon in the Philippines.
As massive as Hurricane Florence is, which is bearing down on the Carolinas, Super Typhoon Mangkhut is even bigger and has more distance and time to grow further.
It is now barrelling across the Pacific with gusts of 255km per hour.
TYPHOON MANGKHUT, which will be locally named Ompong once it enters the Philippine Area of Responsibility (PAR), has intensified as it moves westward towards the northern part of the country.
The Philippine Red Cross estimates three million Filipinos live in the direct path of Mangkhut, communications officer Mary Joy Evalarosa told AFP.
The strongest typhoon to hit the Philippines this year is also threatening farmlands in Northern Luzon just before the rice and corn harvest.
PAGASA defines a super typhoon as a weather disturbance carrying more than 220 kilometers per hour (kph) of maximum center winds.
A woman, accompanied by her young family members, writes the name of a loved one on a cross at a mass graveyard for victims of typhoon Haiyan during All-Saints' Day in Tacloban City, Leyte province, central Philippines on November 1, 2015. The remnants of the storm will still be in the area as Mangkhut arrives Sunday, bringing no relief to Hong Kongers from the weather.
Forecaster Meno Mendoza said Mangkhut's strong winds could whip up storm surges while heavy rain could trigger landslides and floods.
