In the early morning of July 1, the National Center for Hydro-Meteorological Forecasting issued a series of warnings on the low-pressure area over the East Sea, hazardous marine conditions and heavy rainfall across northern Vietnam.
At 1 a.m. on July 1, the center of the low-pressure area was located between 14.5 and 15.5 degrees North latitude and 117.5 and 118.5 degrees East longitude, over the eastern waters of the northern East Sea and the central East Sea.
Forecasters said that the system is expected to move west-northwest at a speed of 10-15 kilometers per hour over the next 24 hours and is likely to develop into a tropical depression.
Under its influence, winds are forecast to strengthen to force 6, with gusts of force 7-8, over the eastern waters of the northern East Sea, the central and southern East Sea, including Truong Sa Special Zone, as well as the waters stretching from Lam Dong to Vinh Long provinces. Wave heights are expected to reach two to three meters, resulting in rough seas.
Throughout July 1, scattered showers and thunderstorms are forecast for the Gulf of Tonkin, the southeastern waters of the northern East Sea, the central and southern East Sea, waters from Lam Dong to Ca Mau, from Ca Mau to An Giang, and the Gulf of Thailand.
Thunderstorms may be accompanied by waterspouts, strong wind gusts of force 7-8 and waves exceeding two meters, posing significant risks to vessels operating in these waters.
