SANVU is expected to continue moving ENE for the next 24 hours, and will accelerate on the same track through Tuesday. On the forecast track, the core of SANVU will pass over or very close to Iwo To this morning and will be well to the East of Chichi Jima by early Sunday.

Maximum Sustained Winds (1-min. avg) are near 140 km/hr (75 knots) with higher gusts. SANVU is expected to lose strength through Monday. This system will become an Extratropical Cyclone on Monday.

Typhoon Force Winds (118 km/hr or more) extend outward up to 55 kilometers (30 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 260 kilometers (140 nautical miles). SANVU is an average-sized tropical cyclone with a diameter of 600 kilometers (323 nautical miles).

The following is the summary of the 3-day forecast outlook on this system:

SUNDAY EARLY MORNING:  Downgraded to a Tropical Storm as it moves farther away from Iwo To [2AM MAY 27: 26.7N 144.7E @ 110kph].
MONDAY EARLY MORNING:  Becoming Extratropical...continues to weaken [2AM MAY 28: 30.9N 151.7E @ 75kph].
TUESDAY EARLY MORNING:  Attains Extratropical status...accelerating rapidly across the open seas [2AM MAY 29: 34.6N 160.4E @ 65kph].

*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:

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).
NORTHERN EYEWALL - moving across 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. 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.
