+ Forecast Outlook: NIDA is expected to drift very slowly northward and will start decaying within the next 2 days. The 3 to 5-day Long-Range Forecast shows the system downgraded to a Tropical Storm as strong upper-level winds (Vertical Wind Shear) affects the system on Wednesday morning (8AM Dec 02: 22.3N 140.3E)...about 295 km SSW of Iwo To. NIDA will continue to rapidly decay - turning more to the West slowly and dissipate to the SW of Iwo To beginning Thursday until Friday (8AM Dec 03: 22.8N 140.2E...8AM Dec 4: 22.5N 139.5E). There are still some models that forecast the soon-to-be-dissipating system tracking West to WSW into the Philippine Sea due to the strong surge of NE Monsoon (Amihan) approaching from China. Please be reminded that the Forecast Outlook changes every 6 hours, so a turn to the left or right of its future track and other possibilities must be considered.

+ Effects & Hazards: NIDA is not affecting any major islands at this time. 6-hr total rainfall amounts of 5 up to 150 mm (light to moderate rain) can be expected along the outer and inner bands...with isolated amounts of 250 mm (heavy rain) near the center or EyeWall of Nida.

+ Current NE Monsoon Intensity: LIGHT >> Sunny, clear to cloudy skies with possible passing rains, squalls (subasko) can be expected along the following affected areas: PORTIONS OF NORTHERN AND EASTERN LUZON. Light to moderate northeasterly winds (not in excess of 35 kph) can be expected on these 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!]
