2-DAY FORECAST OUTLOOK & ANALYSIS*

BOLAVEN (JULIAN) is expected to move rapidly Northward during the next 24 hours...recurving to the NNE to NE thru 48 hours. On the forecast track, the core of BOLAVEN will move across the East China and into the Yellow Sea today thru Tuesday afternoon - passing close to the west of Jeju Island early Tuesday morning. By late Tuesday afternoon, Bolaven will make landfall over North Korea, passing very close to Pyongyang and cross the communist nation thru Wednesday early morning...and will be off Northeastern China by Wednesday afternoon.

Maximum Sustained Winds (1-min. avg) have decreased to near 140 km/hr (75 knots) with higher gusts. A decrease in strength will continue throughout the forecast period...and BOLAVEN will be downgraded into a Tropical Storm (TS) before it makes landfall over North Korea on Tuesday afternoon.

Typhoon Force Winds (118 km/hr or more) extend outward up to 100 kilometers (55 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 315 kilometers (170 nautical miles). BOLAVEN is a very large-sized tropical cyclone with a diameter of 1205 kilometers (650 nautical miles) across.

The following is the summary of the 2-day forecast outlook on this system:

TUESDAY AFTERNOON: Weakens to a Tropical Storm as it prepares to make landfall over North Korea [5PM AUG 28: 37.7N 125.5E @ 110kph].
WEDNESDAY AFTERNOON: Losing tropical characteristics...moving inland across NE China...about 350 km NW of Vladivostok, Eastern Russia [5PM AUG 29: 46.0N 129.8E @ 75kph].

*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.

EFFECTS & HAZARDS SUMMARY

Below is the summary of the storm's parts and its hazards affecting specific areas. You can also view this image link for you to understand the parts.

CLOUD-FILLED EYE - over water (East China Sea). Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE).
DECAYING EYEWALL - over water (East China Sea). Typhoon Conditions with Typhoon Force Winds (>118 kph) will be expected within this wall (click here to know more about the Eyewall).
INNER RAINBANDS - affecting and spreading across Jeju Island. Tropical Storm Conditions with Tropical Storm Force Winds (62-117 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across Okinawa-Ryukyu-Amami Islands, Kyushu (Japan), Coastal Areas of Eastern China and the Korean Peninsula. Cloudy/Rainy Conditions with 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 230 mm (high) along areas near the center of Bolaven (Julian) (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 Jeju Island and the Korean Peninsula. Minimal damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the rest of the beach-front areas of Kyushu, Eastern China, Ryukyus and Amami Islands (click here to know more about Storm Surge).

Important Note: Please keep in mind that the above forecast outlook, effects-hazards, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!
