Xangsane is currently gathering strength again over the South China Sea and is back to cat 4 (115 kts) after it weakened to a cat 2 (or just a tropical storm, depending on which meteorological service you believe). It is now moving almost due west and should reach the coast of Vietnam sometime late tomorrow. JTWC forecast takes the intensity up to 125 kts. but then weakens it a little to 120 kts. before landfall. The storm is expected to slow down considerably as it moves inland so flash flooding may be the biggest danger.

Don't really know how heavily populated that area is, but I hope they are prepared.
