Typhoon Rammasun is well-structured with a 20 nautical mile diameter eye after rapid intensification overnight. This image taken by the JMA MTSAT-2 satellite at 0830Z on July 15, 2014, shows Rapu-Rapu Island in the center of the eye. As the storm tracks toward Manila weakening is forecast as it interacts with land bringing with it possibilities for heavy flooding and mudslides. Rammasun is expected to reintensify as it enters the South China Sea due to a favorable upper-level environment and warm sea surface temperatures. Landfall on northern Hainan Island is expected in three days, and the storm is expected to maintain Typhoon strength for its final landfall in northern Vietnam near Hanoi.
