GUCHOL (BUTCHOY) is expected to continue moving north-northwestward with a faster speed for the next 24 to 36 hours and will turn Northward by 48 hours. By 72 hours, GUCHOL will start recurving towards the NNE. On the forecast track, the core of GUCHOL will just move across the open waters of the North Philippine Sea, passing more or less 500 km to the east of the Philippines through Monday - without hitting any land areas. It will be moving out of the Philippine Area of Responsibility (PAR) on Monday evening and will pass very close to Okinawa on Tuesday.

Maximum Sustained Winds (1-min. avg) have increased to near 185 km/hr (100 knots) with higher gusts. GUCHOL will continue gaining strength and will become a dangerous Category 4 Typhoon on Monday.

Typhoon Force Winds (118 km/hr or more) extend outward up to 65 kilometers (35 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 160 kilometers (85 nautical miles. GUCHOL is an average-sized tropical cyclone with a diameter of 520 kilometers (280 nautical miles).
