01W is expected to track slowly southward across the South China Sea for the next 2 days. It will start to weaken later today [2PM APR 03: 9.2N 111.8E @ 45kph], and by early Monday morning, 01W will eventually dissipate due to moderate-to-strong upper-level winds along the area...losing depression status [2AM APR 04: 8.5N 111.8E @ 35kph...2PM APR 04: 7.8N 111.6E @ 35kph].
Maximum Sustained Winds (1-min. avg) are near 55 km/hr (30 knots) with higher gusts. 01W is a Tropical Depression on the Saffir-Simpson Tropical Cyclone Scale.
*Please be reminded that the Forecast Outlook changes every 6 hours, and the Extended Forecast Track have an average error of 250 km on Day 3...450 km on Day 4...and 650 km on Day 5, 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.
EFFECTS & HAZARDS SUMMARY
01W rainbands will continue to affect the coastal areas of Southeastern & Southern Vietnam today. Below are the summary of the depression's parts and its hazards affecting specific areas: 
WESTERN OUTER RAINBANDS - affecting Southeastern & Southern Vietnam. Where light to moderate winds (<35 kph) w/ occasional rains can be expected along these bands today. (click here to know more about Rainbands).
TROPICAL CYCLONE WATCH Important Note: Please keep in mind that the above forecast outlook, extended forecast, effects-hazards, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!
Tropical Disturbance 95W (LPA/1003 MB) gaining strength while remaining almost stationary over the Philippine Sea, east of Southern Samar. It was located near lat 10.1N lon 130.3E...about 525 km ENE of Surigao City, NE Mindanao or 560 km ESE of Borongan, Eastern Samar...with 1-min maximum sustained winds of 35 kph near the center. Its western rainbands are affecting the coastal areas of Eastern Visayas and Northeastern Mindanao. The 48-Hr. Tropical Cyclone Formation Potential on this system is now @ 70%.

JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 2 AM (18 GMT) SUN 03 APRIL POSITION: 9.5N 111.6E.
*ANIMATED INFRARED SATELLITE IMAGERY CLEARLY DEPICTS AN EXPOSED, WELL-
DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH AN ISOLATED BURST OF
DEEP CONVECTION OVER THE NORTHWEST QUADRANT. DEEP CONVECTION HAS
CONTINUED TO STRUGGLE DUE TO MODERATE TO HIGH (20-25 KNOTS) VERTICAL
WIND SHEAR (VWS). REGARDLESS OF THE LACK OF DEEP CONVECTION, THE
SYSTEM HAS MAINTAINED TROPICAL DEPRESSION STRENGTH BASED ON RECENT
OBSERVATIONAL DATA. SHIP OBSERVATIONS, ABOUT 100 NM WEST OF THE
CENTER, HAVE INDICATED 25-30 KNOT NORTHERLY WINDS WHILE A 021026Z
WINDSAT IMAGE SHOWED 20-25 KNOT WINDS NEAR THE CENTER AND 25-30 KNOT
NORTHERLY WINDS OVER THE WESTERN PERIPHERY OF THE SYSTEM. THERE IS
GOOD CONFIDENCE IN THE CURRENT POSITION BASED ON THE EXPOSED CENTER.
THE CURRENT INTENSITY OF 30 KNOTS IS BASED LARGELY ON THE SHIP
OBSERVATIONS AND WINDSAT DATA. TD 01W IS FORECAST TO REMAIN QUASI-
STATIONARY THROUGH THE PERIOD BUT WILL LIKELY TRACK SOUTHWARD AS IT
WEAKENS. THE SYSTEM WILL ALMOST CERTAINLY WEAKEN DUE TO PERSISTENT,
UNFAVORABLE VWS AND DRY AIR ENTRAINMENT. OBSERVATIONS INDICATE DRY
AIR WEST AND NORTH OF THE SYSTEM ASSOCIATED WITH THE NORTHEAST
MONSOON SURGE WITH DEW POINTS UNDER 20C. THE SYSTEM IS FORECAST TO
WEAKEN BELOW 25 KNOTS AFTER TAU 12 AND TO DISSIPATE BY TAU 24...(more)
