      Below is the summary of the storm's parts and its hazards affecting specific areas:

      CENTRAL DENSE OVERCAST (CDO) - over water (South China Sea)...not affecting any land areas. Tropical Storm Conditions w/ Tropical Storm Force Winds (62-100 kph) will be expected along the CDO. (click here to know more about CDO).
      INNER RAINBANDS - over water (South China Sea)...not affecting land areas. Tropical Depression Conditions w/ Strong Winds (45-61 kph) will be expected along these bands.
      OUTER RAINBANDS - over water (South China Sea)...not affecting any land areas. Cloudy/Rainy Conditions w/ light to moderate winds (<44 kph) will be expected along these bands (click here to know more about Rainbands).
      24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 200 mm (low to high rainfall) can be expected along areas affected by the rainbands (see above)...with isolated amounts of 201 to 350 mm (high) along areas near the center of WASHI (SENDONG). (click to open NOAA's eTRaP graphic).
      COASTAL STORM SURGE FLOODING - possible 1-3 ft [0.3-0.9 m] above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal, inland lakes and beach front areas of Vietnam. Very minimal damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the beach-front areas of Palawan.
