3-DAY FORECAST OUTLOOK & ANALYSIS*
KAI-TAK (HELEN) is expected to move WNW to NW-ward during the next 24 to 48 hours...before turning generally WNW-ward through 72 hours. Some fluctuation in its forward speed is likely throughout the forecast period. On the forecast track, the core of KAI-TAK will traverse Northern Luzon...passing across the provinces Isabela and Cagayan (passing in between the cities of Ilagan & Tuguegarao) this morning...Kalinga and Apayao around noontime...and Ilocos Norte in the afternoon. KAI-TAK will then emerge over the West Philippine Sea later tonight, after passing over or very close to Laoag City...and then move out of the Philippine Area of Responsibility (PAR) on Thursday morning. By Friday noon, KAI-TAK is forecast to make landfall over Southern China very near Hong Kong.
Maximum Sustained Winds (1-min. avg) are near 95 km/hr (50 knots) with higher gusts. Continued strengthening is forecast during the next 2 days...and KAI-TAK could become a Typhoon on Thursday.
Tropical Storm Force Winds (62-100 km/hr) extend outward up to 130 kilometers (70 nautical miles) from the center. KAI-TAK is a large-sized tropical cyclone with a diameter of 775 kilometers (420 nautical miles) across.
