As expected, Tropical Storm Rammasun intensified on the track to the Philippines and became Typhoon Rammasun during July 14, 2014. The Philippines are bracing for the impact of first typhoon since the devastating Super Typhoon Haiyan in November 2013.
According to JTWC, the system is moving westward at speed of 24 km/h (15 mph). At 21:00 UTC on July 14, 2014 maximum sustained winds were 150 km/h (92 mph) with gusts up to 185 km/h (115 mph).

PAGASA, the national weather agency in the Philippines, has named the storm "Glenda". PAGASA expects the typhoon to make landfall in the Albay-Sorsogon area, towards Southern Luzon.
As outer bands of rain begin to move onshore, damaging winds and flooding rainfall are expected across the north-central and northern Philippines. Northern Visayas and southern Luzon will see the greatest impact. Samar and Catanduanes Islands will experience strong winds and storm surge along the coast.

The Joint Typhoon Warning Center expects Rammasun to move across the central and northern Philippines in a northwesterly direction crossing near Manila early on July 16, 2014, then moving into the South China Sea for another landfall in mainland China, just north of Hainan Island late on July 18, 2014 as a typhoon.
NASA-NOAA's Suomi NPP satellite passed over Typhoon Rammasun early on July 14, 2014 and captured a visible image of the storm that showed large bands of thunderstorms wrapping into the center as it approached the central Philippines. The VIIRS instrument aboard Suomi NPP satellite captured this visible image of Typhoon Rammasun on July 14 at 04:20 UTC. The VIIRS instrument showed large, thick bands of powerful thunderstorms wrapping into the low-level center of circulation. The largest band extended from the western to southern and around to the eastern quadrants of the storm before spiraling into the center. Powerful thunderstorms also surrounded the tightly wound eye.

The favorable environment and conducive sea surface temperatures will allow further intensification before the system begins to interact with land where some weakening is forecast through the next couple of days.
Once the system crosses the Philippines and exits north of Subic Bay into the warm waters of the South China Sea favorable conditions will help the system to intensify before making a second landfall in China near Hainan Island on July 18, 2014. Landfall is expected around northern Haiyan Island across the Luichow Peninsula and western Guangdong provinces.
JTWC expects that Rammasun will cross the Gulf of Tonkin and make a final landfall over northern Vietnam near Hanoi.
