NALGAE (QUIEL) will move generally westward (known in meteorology as a "Straight-Runner") throughout the forecast period, with little change in its forward speed. On the forecast track, the core of the typhoon will traverse the shores of Cagayan and Ilocos Norte Saturday evening (Oct 1) through Sunday early morning (Oct 02)...and be over the West Philippine Sea (South China Sea) by Sunday afternoon.

Typhoon Force Winds (118 km/hr or more) extend outward up to 20 kilometers (10 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 160 kilometers (85 nautical miles). NALGAE is a small to average-sized tropical cyclone with a diameter of 390 kilometers (210 nautical miles).

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