INNER RAINBANDS - affecting and spreading across Guam. Tropical Storm Conditions with Tropical Storm Force Winds (62-94 kph) will be expected along these bands today.
OUTER RAINBANDS - affecting & spreading across the Southern and Northern Mariana Islands. Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands tonight and tomorrow (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 330 mm (high) along areas near the center of 03W (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 Northern Marianas today. 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 the rest of Marianas.
