Typhoon Rammasun about to reach super typhoon strength

Deadly Typhoon Rammasun (locally known as Glenda) left trail of destruction across the Philippines. According to the National Disaster Risk Reduction and Management Council of the Philippines, 40 people have been killed by the storm while more remain missing or injured.

After leaving the Philippines, and tracking across high sea surface temperatures (30-31 degrees Celsius), and low vertical wind shear, Typhoon Rammasun has quickly intensified into a Category 4 typhoon, with maximum sustained winds of 225 km/h (140 mph).

According to latest report by the Joint Typhoon Warning Center (JTWC), the center of Typhoon Rammasun is located approximately 232 nm south of Hong Kong, and is moving northwestward at speed of 24 km/h (15 mph). Maximum sustained winds are 222 km/h (120 mph) with gusts up to 270 km/h (145 mph).  JTWC expects Rammasun to continue to strengthen before reaching land, possibly reaching super typhoon status with winds of above 240 km/h (150 mph) and gusts up to 296 km/h (184 mph) before landfall.
