FORECAST OUTLOOK ANALYSIS (up to 36 hours)*
01W is expected to continue drifting slowly southward across the South China Sea for the next 24 to 36 hours. It will start to weaken later tonight [8PM APR 03: 8.8N 111.9E @ 45kph], and around Monday morning, 01W will eventually dissipate due to moderate-to-strong upper-level winds (aka. vertical wind shear) along the area...losing its depression status [8AM APR 04: 8.1N 111.8E @ 35kph...8PM APR 04: 7.3N 111.5E @ 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's outer periphery will continue to affect the coastal areas of Southeastern Vietnam today. Below are the summary of the depression's parts and its hazards affecting specific areas: 
WESTERN OUTER RAINBANDS - affecting the coastal areas of Southeastern 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) has drifted slowly ESE-ward during the past 6 hours while over the Philippine Sea. It was located near lat 9.5N lon 131.1E...about 615 km East of Surigao City, NE Mindanao or 665 km ESE of Borongan, Eastern Samar...with 1-min maximum sustained winds of 35 kph near the center. Its western rainbands have retreated away from the coast of Eastern Visayas and Northeastern Mindanao - thus, improving weather conditions can be expected. Various Computer Guidance Models are forecasting 95W to reach Tropical Depression status within 06 to 24 hours and will track East to ENE-ward in the direction of the Northern Mariana Islands - away from the Philippine Islands. The 48-Hr. Tropical Cyclone Formation Potential on this system is now @ 90%. Click here to view current satellite visible image and flash animation.

JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 8 AM (00 GMT) SUN 03 APRIL POSITION: 9.3N 111.8E.
*ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A PARTIALLY-EXPOSED LOW-
LEVEL CIRCULATION CENTER (LLCC) WITH DEEP CONVECTION PERSISTING OVER
THE NORTHWEST QUADRANT. A 022254Z SSMIS IMAGE INDICATES LOW-LEVEL
CONVECTIVE BANDING WRAPPING FROM THE SOUTH INTO THE NORTH 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 CONVECTIVE BANDING, THE SYSTEM HAS MAINTAINED TROPICAL
DEPRESSION STRENGTH. THERE IS GOOD CONFIDENCE IN THE CURRENT
POSITION BASED ON THE EXPOSED CENTER. THE CURRENT INTENSITY OF 30
KNOTS IS BASED ON PERSISTENCE AND THE WELL-DEFINED NATURE OF THE
LLCC...(more)
