HAIKUI (12W) is expected to move WNW to NW-ward during the next 24 to 48 hours...recurving sharply to the NE after 48 hours. Its general motion will remain slow during the next couple of days. On the forecast track, the core of HAIKUI will continue to move across the East China Sea today until Wednesday morning...and will make landfall over Zhejiang Province in Southeastern China, just south of the city of Ningbo by Wednesday afternoon.

Maximum Sustained Winds (1-min. avg) are near 120 km/hr (65 knots) with higher gusts. Some weakening is forecast during the next 12 to 24 hours before HAIKUI makes landfall due to interaction with the Chinese Coast. Rapid dissipation of the typhoon will be expected as HAIKUI moves over land.

Tropical Storm Force Winds (62-100 km/hr) extend outward up to 185 kilometers (100 nautical miles) from the center. HAIKUI is a large-sized tropical cyclone with a diameter of 665 kilometers (360 nautical miles) across.

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

THURSDAY AFTERNOON: Downgraded to a Tropical Storm (TS) as the cyclone makes landfall over Zhejiang Province...about 68 km SW of Ningbo City, China [5PM AUG 08: 29.4N 121.1E @ 95kph].
FRIDAY AFTERNOON: Starts to recurve to the NE...just an area of low pressure as it continues to dissipate over Zhejiang Province...about 150 km WSW of Shanghai, China [5PM AUG 09: 30.6N 120.0E @ 35kph].

*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 (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).
EYEWALL - over water (Near the Coast of Zhejiang Province)...not yet affecting any land areas...but will reach and affect the shoreline of Zhejiang Province later tonight or early Wednesday. 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 Zhejiang Province. Tropical Storm Conditions with Tropical Storm Force Winds (62-100 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across Okinawa-Ryukyu Islands, Taiwan and the rest of Eastern and Southeastern China. 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 400 mm (high to very high) along areas near the center of Haikui (12W) (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 Eastern & SE China, Northern Taiwan, Okinawa, Amami and the Rest of the Ryukyu Islands. 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 Western Japan, Extreme Northern Luzon, and South Korea.
