GUCHOL is expected to decrease on its westerly track w/in the next 6 to 12 hours and will turn sharply to the WNW to NW between 24 to 48 hours. It will then move almost northerly by 72 hours. On the forecast track, the core of GUCHOL will just move across the Philippine Sea, passing more or less 300 km to the east of the Philippines through Monday - without hitting any land areas.

Maximum Sustained Winds (1-min. avg) have increased to near 150 km/hr (80 knots) with higher gusts. GUCHOL will continue gaining strength and will become a Category 2 Typhoon (TY) this morning.

Typhoon Force Winds (118 km/hr or more) extend outward up to 45 kilometers (25 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 140 kilometers (75 nautical miles. GUCHOL is a small-sized tropical cyclone with a diameter of 335 kilometers (180 nautical miles).

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

SATURDAY EARLY MORNING: Turns northwestward while still over the Philippine Sea...wind intensity at Category 2 [2AM JUN 16: 11.5N 129.6E @ 175kph].
