3-DAY FORECAST OUTLOOK & ANALYSIS*
GUCHOL (BUTCHOY) is expected to move north-northeast to northeastward for the next 2 to 3 days. On the forecast track, the core of GUCHOL will move out of the Philippine Area of Responsibility (PAR) early tonight and will be passing close to the east of Okinawa just before midnight. GUCHOL will finally be making landfall over Eastern Shikoku and cross Central Honshu on Tuesday evening, passing very near or over Kyoto, Japan. The system will move out into the Sea of Japan on Wednesday and traverse Hokkaido by early Wednesday.
Maximum Sustained Winds (1-min. avg) have decreased to near 195 km/hr (105 knots) with higher gusts. Continued decrease in its strength is anticipated as GUCHOL moves into an area of unfavorable atmospheric conditions and starts transitioning into an Extratropical Cyclone on Wednesday.
Typhoon Force Winds (118 km/hr or more) extend outward up to 100 kilometers (55 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 305 kilometers (165 nautical miles. GUCHOL is a large-sized tropical cyclone with a diameter of 780 kilometers (420 nautical miles).
The following is the summary of the 3-day forecast outlook on this system:
TUESDAY AFTERNOON: Weakens to Category 1 as it bears down the coast of Shikoku, Japan...accelerating very rapidly NE-ward [2PM JUN 19: 32.7N 133.7E @ 130kph].
WEDNESDAY AFTERNOON: Downgraded to a Tropical Storm (TS) while over Hokkaido, Japan...becomes Extratropical [2PM JUN 20: 42.3N 141.1E @ 85kph].
THURSDAY AFTERNOON: A weakening Extratropical system turning ESE-ward off to the south of Kuril Islands [2PM JUN 21: 42.1N 149.0E @ 65kph].
*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 3 Forecast Track have an average error of 250 km...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
Below is the summary of the storm's parts and its hazards affecting specific areas:
EYE - over water (North Philippine Sea). Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE). EYEWALL - over water (North Philippine Sea). Typhoon Conditions with Typhoon Force Winds (>118 kph) will be expected within this wall (click here to know more about the Eyewall). INNER RAINBANDS - over water (North Philippine Sea)...not affecting any land areas...expected to reach Okinawa later tonight and across other parts of Ryukyus early Tuesday. Tropical Storm Conditions with Tropical Storm Force Winds (62-100 kph) will be expected along these bands. OUTER RAINBANDS - affecting & spreading across Okinawa and will reach other parts of Ryukyus tonight. Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands (click here to know more about Rainbands). 24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 100 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 101 to 200 mm (high) along areas near the center of Guchol (Butchoy).

COASTAL STORM SURGE FLOODING - possible 9-12 ft [2.7-3.9 m] above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal, inland lakes and beach front areas of Okinawa and Ryukyu Islands. Extensive damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the beach-front areas of Northern Philippines, Southern Japan and Taiwan.
