INNER RAINBANDS - over water (West Philippine Sea)...no longer affecting land areas. Tropical Depression Conditions w/ Strong Winds (45-61 kph) will be expected along these bands. OUTER RAINBANDS - affecting & spreading across some portions of Palawan. 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 320 mm (high) along areas near the center of WASHI (SENDONG).
