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

INNER RAINBANDS - over water (Western Pacific Ocean)...not yet affecting any land areas. Tropical Storm Conditions with Tropical Storm Force Winds (62-85 kph) will be expected along these bands.
DEVELOPING RAINBANDS - affecting & spreading across the Yap, Ulithi and nearby 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 200 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 201 to 400 mm (high to very high) along areas near the center of 05W (UNNAMED). (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. 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 Eastern Philippines.
