3-DAY FORECAST OUTLOOK & ANALYSIS*
WASHI (SENDONG) is expected to continue moving West to WNW for the next 2 to 3 days...with little change in its forward speed. On the forecast track, the core of WASHI will cross Agusan Del Sur & Bukidnon tonight, passing in between the cities of Iligan & Cagayan De Oro around midnight & will be along Iligan Bay by early Saturday morning (approx. 2-3AM). It will then move across Misamis Occidental & Zamboanga Del Norte by Sunrise Saturday as it passes very close to Dipolog & Dapitan Cities. By Saturday afternoon, WASHI will be moving across Sulu Sea and will start to pass over Southern Palawan early Sunday morning. This storm will therefore pass very close to Spratlys on Sunday afternoon, before moving out of the Philippine Area of Responsibility (PAR) Sunday evening. It will intensify further to near-typhoon strength while over the South China Sea on Monday afternoon.
Maximum Sustained Winds (1-min. avg) have decreased to near 75 km/hr (40 knots) with higher gusts. WASHI (SENDONG) is a Tropical Storm (TS) on the Saffir-Simpson Tropical Cyclone Scale. Rapid weakening of this system is forecast during the next 6-12 hours...and WASHI could be downgraded to a Tropical Depression due to its interaction with Mindanao's massive land mass.
Tropical Storm Force Winds (62-95 km/hr) extend outward up to 95 kilometers (50 nautical miles) from the center. WASHI (SENDONG) is an average-sized tropical cyclone with a diameter of 500 kilometers (270 nautical miles).
The following is the summary of the 3-day forecast outlook on this system:
SATURDAY AFTERNOON: Moving across the Sulu Sea, with regained strength...heading towards Palawan [2PM DEC 17: 8.8N 121.4E @ 65kph].
SUNDAY AFTERNOON: Intensifying while over the West Philippine Sea...passing near the Spratly Islands...turns westward [2PM DEC 18: 9.5N 116.4E @ 85kph].
MONDAY AFTERNOON: Exits PAR as it moves into the southern portion of the South China Sea...turns WSW-ward [2PM DEC 19: 9.4N 111.9E @ 100kph].
