FORECAST OUTLOOK ANALYSIS (up to 24 hours)*
CHABA is expected to become Extratropical later this afternoon or tonight. The decaying cyclone will pass more or less 150 km South of Tokyo late this afternoon to early evening, between 6-9 PM Japan Time (09-12 GMT) [8PM OCT 30: 34.8N 141.4E @ 100kph...8AM OCT 31: 37.6N 146.4E @ 75kph].
Maximum Sustained Winds (1-min. avg) are near 130 km/hr (70 knots) with higher gusts. CHABA is a Category 1 Typhoon on the Saffir-Simpson Tropical Cyclone Scale. Typhoon Force Winds (118 km/hr or more) extend outward up to 55 kilometers (30 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 390 kilometers (210 nautical miles). CHABA is a large-sized tropical cyclone with a diameter of 890 kilometers (480 nautical miles).
*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
CHABA's circulation continues to decay as it moves over an area of unfavorable environment. Below are the summary of the typhoon's parts and its hazards affecting specific areas:
CENTRAL DENSE OVERCAST (CDO) - breaking down as it remains at sea (south of Japan)...not affecting land areas. (click here to know more about CDO).
WEAKENING EYEWALL - remains at sea (south of Japan)...not affecting land areas. Typhoon Conditions with typhoon force winds (>118 kph) can be expected within this wall (click here to know more about the Eyewall).
NORTHERN SPIRAL RAINBANDS - spreading across Southern Honshu...becoming more intense along the coast. Tropical Storm Conditions w/ Tropical Storm Force Winds (65-117 kph) can be expected along these bands. (click here to know more about Rainbands).
24-HR TOTAL RAINFALL ACCUMULATION - from 5 up to 100 mm (light to moderate rain) can be expected along the outer & inner rainbands...with isolated amounts of up to 150 mm (moderate) near the center of CHABA [click to open NOAA's eTRaP graphic].
COASTAL STORM SURGE FLOODING - possible 1 to 5 feet above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal and beach front areas of Southern Japan, particulartly Southern and Eastern Honshu today. Minimal damage is likely on this type of storm surge. (click here to know more about Storm Surge).
CURRENT NORTHEAST MONSOON INTENSITY: MODERATE >> Partly sunny to mostly cloudy skies with passing showers to widespread rains can be expected along these following affected areas: EASTERN LUZON & BICOL REGION. Lower temperatures (less than 30 degrees celsius) with cooler light to moderate NE winds (not in excess of 30 kph) can be expected today.
CURRENT ITCZ/MONSOON TROUGH INTENSITY: MODERATE >> Mostly cloudy skies with scattered to widespread showers, rains & thunderstorms can be expected along these following affected areas: VISAYAS, MASBATE, PALAWAN & MINDANAO. Light to moderate East, SE to variable winds (not in excess of 25 kph) can be expected today.
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!

*TYPHOON (TY) 16W (CHABA), LOCATED APPROXIMATELY 225 NM SOUTH-
SOUTHWEST OF YOKOSUKA, JAPAN, HAS TRACKED NORTHEASTWARD AT 19 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTI-SPECTRAL IMAGERY (MSI) SHOWS
THAT THE EYE HAS COLLAPSED OVER THE PAST FEW HOURS WITH DEEP
CONVECTION SHEARING NORTHEAST OF A PARTIALLY-EXPOSED LOW-LEVEL
CIRCULATION CENTER (LLCC). MSI ALSO DEPICTS FRONTAL CHARACTERISTICS
WITH INCREASING ENTRAINMENT OF COOLER AIR INTO THE WESTERN FLANK OF
THE SYSTEM AND A WARM FRONT EXTENDING SOUTH OF THE KANTO PLAIN. TY
16W IS TRACKING UNDER STRONG (50+ KNOTS) VERTICAL WIND SHEAR
AND HAS BEGUN TO DE-COUPLE. THE 34-KNOT WIND RADII ARE BASED PARTLY
ON OBSERVATIONS FROM JAPANESE COASTAL STATIONS AND OFF-SHORE ISLANDS
REPORTING GALE FORCE WINDS. THE CURRENT INTENSITY IS BASED ON AN
AVERAGE OF DVORAK ESTIMATES RANGING FROM 65 (RJTD, KNES) TO 77 KNOTS
