FRIDAY AFTERNOON:  Still intensifying as it recurves northeastward...approaching Iwo To [2PM MAY 25: 23.0N 140.2E @ 140kph].
SATURDAY AFTERNOON:  Downgraded to a Tropical Storm after passing very close to Iwo To...becoming Extratropical [2PM MAY 26: 26.0N 143.8E @ 110kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 3 Forecast Track have an average error of 250 km...while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.


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

INNER RAINBANDS - remains 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 today.
OUTER RAINBANDS - still affecting & spreading across the Northernmost portion of the Mariana Islands. Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands today (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 SANVU (03W). (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 Iwo To beginning Thursday. 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 Marianas, Iwo To and Chichi Jima.
