3-DAY FORECAST OUTLOOK & ANALYSIS*

BANYAN (RAMON) is expected to continue moving NW-ward during the next 2 to 3 days...with a decrease on its forward speed later in the forecast. On the forecast track, the core of the storm will be approaching the NE Coast of Surigao Del Norte tonight...passing over or very near Surigao City Wednesday morning...and will traverse the major islands of the Visayas (SW Leyte-Camotes Island-Northern Cebu-Northern Coast of Negros-Extreme Northern Panay) Wednesday afternoon through Thursday morning. BANYAN will be crossing Southern Mindoro Thursday afternoon...and will be over the West Philippine Sea on Friday.

Maximum Sustained Winds (1-min. avg) have increased to near 65 km/hr (35 knots) with higher gusts. BANYAN (RAMON) is now a Tropical Storm (TS) on the Saffir-Simpson Tropical Cyclone Scale...and should still intensify before it interacts with the Visayan Islands Wednesday.

Tropical Storm Force Winds (62-85 km/hr) extend outward up to 30 kilometers (15 nautical miles). BANYAN (RAMON) is an average-sized tropical cyclone with a diameter of 665 kilometers (360 nautical miles).

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

WEDNESDAY AFTERNOON:  In the vicinity of Camotes Islands...approaching Northern Cebu...downgraded to a Tropical Depression (TD). [2PM OCT 12: 10.5N 125.4E @ 55kph].
THURSDAY AFTERNOON:  Maintains its TD strength...traversing Southern Mindoro, just to the north of San Jose [2PM OCT 13: 12.6N 121.1E @ 55kph].
FRIDAY AFTERNOON:  Strengthens into a Tropical Storm (TS) while moving NW'ly across the West Philippine Sea [2PM OCT 14: 14.9N 118.2E @ 75kph].

**Alternate Forecast Scenario (AFS): There is a possibility that BANYAN (RAMON) will move more northwesterly to NNW-ward and pass over Tacloban City instead...cutting across Biliran-Ticao...and moving along the western shores of Sorsogon, Albay, Camarines Sur...and make landfall along Southern Quezon towards Metro Manila. This scenario may happen if the High Pressure Steering Ridge northeast of the storm will weaken.
