    + Effects & Hazards: CONSON's (BASYANG) circulation continues to affect Hainan and Vietnam including the Gulf Of Tonkin, with its center approaching the coast of Northern Vietnam. Its inner (rain) bands is now spreading across the coastal areas of Northern Vietnam...while its outer (feeder) bands remains over the rest of Hainan Island, Eastern & Northern Vietnam and parts of Western Guangdong (China). Strong winds (60-90 kph) w/ moderate to heavy rains can be expected along its inner bands...while moderate to strong winds (30-50 kph) w/ occasional rains is likely along the outer bands. 6-hr total rainfall amounts of 5 up to 100 mm (light, moderate to heavy rain) can be expected along the outer and inner rainbands...with isolated amounts of up to 200 mm (heavy) near the center of CONSON. Click here to view the latest NOAA's eTRaP graphic on the storm's rainfall amount. Residents in low-lying areas & steep slopes must remain alert & seek evacuation for possible life-threatening flash floods, mudslides & landslides due to the anticipated heavy rains brought about by this system. Precautionary measures must be initiated if necessary. Possible coastal Storm Surge flooding of less than 4 feet above normal tide levels...accompanied by large and dangerous battering waves...is possible along the coastal areas of Hainan, Gulf Of Tonkin and Vietnam. Very minimal damage is likely on this type of storm surge.

    + Current ITCZ Intensity: MODERATE >> Partly sunny to cloudy skies with scattered to widespread rains w/ thunderstorms can be expected along the following affected areas: METRO MANILA, CENTRAL LUZON, BICOL, QUEZON, AND MINDORO. Possible landslides, mudslides, mudflows (lahars) and life-threatening flash floods are likely to occur along steep mountain/volcanic slopes, river banks, low-lying & flood-prone areas of the affected areas.

    + Tropical Cyclone Watch:

    Tropical Disturbance 98W (LPA/1010 MB) has weakened while off the Philippine Sea, east of Aurora...currently located near lat 15.3N lon 122.9E...or about 150 km ESE of Baler...with 1-min maximum sustained winds of 25 kph near the center...moving SW slowly. This system has a 30% chance of becoming a Tropical Cyclone w/in the next 24 to 48 hours..

    [Important Note: Please keep in mind that the above forecast outlook, effects, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!]
