MA-ON (08W) is expected to maintain its NW track within the next 12 hours before turning more to the NNW through 48 hours. It shall enter the northeasternmost corner of the Philippine Area of Responsibility (PAR) this afternoon with a little increase in intensity. Below is the summary of the 2-day forecast for this system. 
THIS AFTERNOON (SUN): Regains Category 4 status...enters the northeasternmost corner of the PAR...about 760 km ESE of Okinawa, Japan [2PM JUL 17: 24.1N 134.9E @ 215kph]. TOMORROW EARLY MORNING (MON): Continues to intensify as it turns NNW, exiting the PAR...about 615 km ESE of Okinawa, Japan [2AM JUL 18: 25.7N 133.9E @ 220kph]. TOMORROW AFTERNOON (MON): Maintains its Category 4 status, turns poleward (north)...about 340 km ESE of Naje, Japan [2PM JUL 18: 27.6N 133.1E @ 220kph]. TUESDAY EARLY MORNING: Weakens slowly as it executes recurvature towards the NE...about 315 km SE of Kagoshima City, Japan [2AM JUL 19: 29.6N 132.9E @ 215kph].
Maximum Sustained Winds (1-min. avg) are near 205 km/hr (110 knots) with higher gusts. MA-ON (08W) is a Category 3 Typhoon on the Saffir-Simpson Tropical Cyclone Scale. This system will continue to slowly intensify within the next 12 to 24 hours. Typhoon Force Winds (118 km/hr or more) extend outward up to 95 kilometers (50 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 350 kilometers (190 nautical miles). MA-ON remains a very large-sized tropical cyclone with a diameter of 1,665 kilometers (900 nautical miles) across.

EFFECTS & HAZARDS SUMMARY 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!
MA-ON's (08W) powerful circulation is currently undergoing an Eyewall Replacement Cycle (ERC) as it continues to display a 28-km Eye with an intense eyewall convection surrounding the center. Below is the summary of the storm's parts and its hazards affecting specific areas: EYE (28-KM) - remains over water (Northwestern Pacific)...not affecting any land areas. Possible calm and lull conditions (with <20 kph winds) can be expected inside the eye (click here to know more about the EYE). EYEWALL - remains over water...not affecting any land areas. Typhoon Conditions with typhoon force winds (>118 kph) can be expected within this wall (click here to know more about the Eyewall). INNER RAINBANDS - remains over water...not affecting any land areas. Tropical Storm Conditions w/ Tropical Storm Force Winds (62-117 kph) can be expected along these bands. OUTER RAINBANDS - spreading & affecting the japanese islands of Iwo To, Bonin, & Chichi Jima. Tropical Depression Conditions w/ moderate to strong winds (30-61 kph) can be expected along these bands (click here to know more about Rainbands). 06HR TOTAL RAINFALL ACCUMULATION - from 5 up to 80 mm (low to med rainfall) can be expected along the outer & inner rainbands...with isolated amounts of up to 130 mm (medium-high) near the center of MA-ON (08W).

REMARKS (for Meteorologists): 2 AM (18 GMT) SUN 17 JULY POSITION: 22.7N 136.3E.
*TYPHOON (TY) 08W (MA-ON), LOCATED APPROXIMATELY 785 NM SOUTH-
SOUTHWEST OF TOKYO, JAPAN, HAS TRACKED NORTHWESTWARD AT 11 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
A 15 NM EYE WITH AN EYEWALL SURROUNDING THE CENTER EXCEPT OVER THE
WEST QUADRANT. A 161704Z AMSR-E IMAGE SUGGESTS AN EYEWALL
REPLACEMENT CYCLE (ERC) IS OCCURRING WITH A SMALL INNER EYEWALL
SURROUNDED BY A NEAR COMPLETE OUTER EYEWALL. MICROWAVE IMAGERY
CONTINUES TO DEPICT A LARGE 300-360 NM RADIUS SYSTEM WITH DEEP
CONVECTIVE BANDING EXTENDING AS FAR WEST AS 200 NM. OVERALL, OUTFLOW
HAS IMPROVED ESPECIALLY POLEWARD OUTFLOW WHICH HAS IMPROVED OVER THE
NORTHERN SEMI-CIRCLE AS THE TUTT HAS WEAKENED. THE SYSTEM HAS TURNED
NORTHWESTWARD WITH A MINOR WOBBLE INDICATED IN ANIMATED IMAGERY.
THERE IS HIGH CONFIDENCE IN THE POSITION AND MOTION BASED ON THE
EYE. THE CURRENT INTENSITY IS ASSESSED AT 110 KNOTS BASED ON AN
AVERAGE OF DVORAK ESTIMATES RANGING FROM 102 TO 115 KNOTS. CLOUD TOP
TEMPERATURES, PARTICULARLY OVER THE WESTERN QUADRANT, HAVE WARMED
YET THE EYE TEMPERATURE HAS WARMED. THE CLOUD TOP WARMING IS
EXPECTED TO BE A SHORT-TERM TREND AND TY 08W IS STILL EXPECTED TO RE-
INTENSIFY TO ABOUT 125 KNOTS WITHIN THE NEXT 36 HOURS AFTER THE ERC
IS COMPLETE AND UPPER-LEVEL CONDITIONS CONTINUE TO IMPROVE. THERE IS
GOOD CONFIDENCE IN THE TRACK BASED ON A TIGHT GROUPING OF DYNAMIC
MODELS AND A FAIRLY STRAIGHT FORWARD SYNOPTIC PATTERN. THE 15/12Z
AND 16/12Z 500 MB ANALYSES INDICATE A BROAD AREA OF HEIGHT FALLS
ACROSS EAST ASIA ASSOCIATED WITH THE WEAKENING RIDGE AND
STRENGTHENING WESTERLY FLOW, WHICH IS PUSHING INTO SOUTH KOREA AND
WESTERN JAPAN. THIS FORECAST IS POSITIONED CLOSE TO THE MODEL
CONSENSUS BUT SLIGHTLY FASTER AT THE EXTENDED TAUS...(more info)
