Tropical Storm Force Winds (62-117 km/hr) extend outward up to 85 kilometers (45 nautical miles) from the center. GUCHOL is a small-sized tropical cyclone with a diameter of 295 kilometers (160 nautical miles).

The following is the summary of the 3-day forecast outlook on this system:

FRIDAY EARLY MORNING: Upgraded to typhoon intensity...moving WNW to NW-ward across the Philippine Sea [2AM JUN 15: 12.5N 132.0E @ 120kph].
SATURDAY EARLY MORNING: Still intensifying...with a turn more to the NW...about 472 km ENE of Virac, Catanduanes [2AM JUN 16: 14.8N 128.4E @ 140kph].
SUNDAY EARLY MORNING: Reaches Category 2 strength...turns NNW-ward sparing Luzon...about 446 km East of Tuguegarao City, Cagayan [2AM JUN 17: 17.9N 125.9E @ 160kph].

*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.


Below is the summary of the storm's parts and its hazards affecting specific areas:

CENTRAL DENSE OVERCAST (CDO) - over water (Western Pacific Ocean)...not yet affecting any land areas...possible "Eye" forming underneath the cirrus canopy. Near-Typhoon Conditions w/ Near-Typhoon Force Winds (95-117 kph) will be expected along the CDO. (click here to know more about CDO).
INNER RAINBANDS - over water (Western Pacific Ocean) longer affecting Yap & Ulithi. Tropical Storm Conditions with Tropical Storm Force Winds (62-100 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across the rest of Western Micronesia incl. Palau. 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 200 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 201 to 450 mm (high to very high) along areas near the center of GUCHOL (05W). (click to open NOAA's eTRaP graphic).
COASTAL STORM SURGE FLOODING - possible 1-3 ft [0.3-0.9 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 Yap, Ulithi, Palau and other nearby islands of Micronesia. Very minimal 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 Eastern Philippines.
