First tropical depression of 2010 in W. Pacific
The first tropical depression of 2010 formed today off the coast of Vietnam. The storm is projected to head straight for the southern coast and pass to the south of Ho Chi Minh City as a tropical storm by late Tuesday night or early Wednesday morning.
Forward motion is fairly rapid at 26 MPH. The high forward speed will carry this storm at least to the Cambodian border at tropical storm strength according to Tropical Storm Risk. The storm will pass over the southern portions of Phnom Penh by late Wednesday.
The western Pacific tropical season is the strongest from April through November, but there is always the potential for storm formation throughout the entire year. Equatorial waters in the western Pacific stay quite warm throughout the year and a suitable for cyclone formation.
