OUTER RAINBANDS - affecting & spreading across the rest of Western Micronesia incl. Palau. 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 300 mm (high) along areas near the center of GUCHOL (05W). (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 Yap, Ulithi, Palau and other nearby islands of Micronesia.
