Tropical Depression 25W Update #1

Invest 93W has been upgraded into a Tropical Depression early this morning by the Joint Typhoon Warning Center (JTWC). The system is located in the South China Sea, approximately 600km east of Vietnam.

Latest update from the JTWC shows an estimated sustained winds of around 45kph with gusts of up to 65kph. An ASCAT pass last night picked up the low level circulation center with winds of somewhere around 30 to 50kph. However, convective activity has weakened and the depression has become a bit disorganized these past 6 hours. Based on the trends there is a chance 25W could dissipate sometime today. Nevertheless, the train of showers associated with this depression could still move towards Vietnam over the next couple of days.

Stay tuned for our afternoon update for more on 25W.
Issued (22 UTC) 5am PhT 120511
