+ Forecast Outlook: NIDA is expected to continue on its slow track and weaken further down to Category 3 as it begins recurvature for the the next 2 days. The 3 to 4-day Medium-Range Forecast shows the system downgraded to a Category 1 Typhoon and will begin to enter the mid-latitude westerly windflow (westerlies) & accelerate towards the NE or ENE by Monday morning (8AM Nov 30: 23.6N 143.8E)...about 2,270 km East of Taiwan or 285 km ESE of Iwo To (formerly Iwo Jima). NIDA will continue to move faster ENE-ward across the open seas of the Western Pacific Ocean and become Extratropical by Tuesday (8AM Dec 01: 29.5N 152.4E). Based on this forecast, this system will no longer enter the Philippine Area of Responsibility (PAR).: 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's southeastern outer rainbands still spreading across Marianas including Guam & Saipan, bringing passing rains with squalls across the area. 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 200 mm (heavy rain) near the center of Nida.

Possible coastal Storm Surge flooding of 9 to 12 feet above normal tide levels...accompanied by large and dangerous battering waves...is possible along the coastal areas of Marianas including Guam & Saipan. Extensive damage is likely on this type of storm surge.

+ Current NE Monsoon Intensity: MODERATE >> Partly sunny to cloudy skies & light to moderate northeasterly winds (not in excess of 30 kph) with occasional rains, squalls (subasko) can be expected along the following affected areas: EASTERN LUZON, BICOL REGION, QUEZON, MASBATE, & NORTHERN VISAYAS.

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