According to the National Center for Hydrometeorological Forecasting, Noul officially moved into the East Sea on the night of July 24, becoming the second storm of the year.

At 10 p.m., the center of the storm was over the northeastern waters of the northern East Sea, about 710 km southeast of Hong Kong, China.

Maximum sustained winds near the center reached force 10, or 89-102 km/h, with gusts at force 12. The storm was moving west-northwest at about 25 km/h.

Under the current forecast, Noul will continue moving mainly west-northwest, with a probability of more than 80% that it will make landfall in Guangdong province, China. It is considered unlikely to directly affect Vietnam's mainland.
