CLOUD-FILLED EYE - over water (Western Pacific Ocean). Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE).
WESTERN EYEWALL - affecting Iwo To. Typhoon Conditions with Typhoon Force Winds (>118 kph) will be expected within this wall (click here to know more about the Eyewall).
INNER RAINBANDS - over water (Western Pacific Ocean)...not affecting land areas. Tropical Storm Conditions with Tropical Storm Force Winds (62-100 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across Bonin and Chichi Jima Islands. Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands (click here to know more about Rainbands).
24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 100 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 101 to 200 mm (high) along areas near the center of SANVU (03W). (click to open NOAA's eTRaP graphic).
COASTAL STORM SURGE FLOODING - possible 4-5 ft [1.2-1.7 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 Iwo To, Bonin & Chichi Jima Islands.
