+ Forecast Outlook: CHANTHU is expected to resume its NW track and will intensify further while over the South China Sea [2AM JUL 21: 18.4N 114.7E @ 85kph]. It will be approaching Guangdong, China with forecast 1-min sustained winds of 100 kph by early Thursday [2AM JUL 22: 20.8N 113.5E @ 100kph]. The 3 to 4-day Long-Range Forecast shows CHANTHU making landfall west of Macau by Thursday afternoon, and will move overland, across Guangdong Province (China) [2AM JUL 23: 23.0N 112.2E @ 65kph]. This system will eventually dissipate as it moves across the mountainous terrain of China early Friday morning [2AM JUL 24: 24.5N 110.9E @ 35kph].
+ Effects & Hazards: CHANTHU's circulation continues to become better organized while over the South China Sea. Its extreme-eastern outer (feeder) bands has slightly extended and is currently affecting the coastal areas of Zambales & Western Pangasinan. However, its rain content has weakened somewhat. 6-hr total rainfall amounts of 5 up to 50 mm (light to moderate rain) can be expected along the outer and inner rainbands...
+ Current ITCZ Intensity: MODERATE >> Sunny to mostly cloudy skies with scattered to widespread afternoon or evening rains w/ strong thunderstorms can be expected along the following affected areas: REST OF THE PHILIPPINES. 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.
[Important Note: Please keep in mind that the above forecast outlook, effects, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!]

191809Z AMSR-E MICROWAVE IMAGE SHOW IMPROVED CONVECTIVE BANDING
WRAPPING AROUND A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER
(LLCC) FROM THE SOUTH AND EAST. ENVIRONMENTAL ANALYSIS SHOWS TS
CHANTHU IS LOCATED JUST SOUTH OF AN UPPER LEVEL LOW SUPPORTING GOOD
OUTFLOW ALOFT AND IS IN AN AREA OF LOW VERTICAL WIND SHEAR (VWS). TS
04W HAS RECENTLY TURNED NORTHWARD DUE TO A WEAKNESS IN THE
SUBTROPICAL STEERING RIDGE THAT HAS DEVELOPED IN RESPONSE TO A
PASSING MID-LATITUDE UPPER LEVEL TROUGH TO THE NORTH. AS THE
STEERING RIDGE REBUILDS, TS 04W SHOULD BEGIN TO TRACK MORE
NORTHWESTWARD ALONG THE SOUTHERN PERIPHERY OF A NARROW RIDGE
INDICATED IN UPPER LEVEL OBSERVATIONS FROM CHINA. TS 04W WILL
CONTINUE TO INTENSIFY THROUGHOUT THE FORECAST PERIOD DUE TO GOOD
OUTFLOW, WARM SEA SURFACE TEMPERATURES, AND LOW VWS. IT IS FORECAST
TO MAKE LANDFALL AFTER TAU 48 AND BEGIN TO DISSIPATE OVER LAND.
AVAILABLE NUMERICAL MODEL GUIDANCE IS SPREAD AS TO EXACTLY WHERE TS
04W WILL REACH LAND.....(more)
