Tropical Storm Ulysses

10 Nov 2020 / Philippines

A Tropical Cyclone Warning was issued in the Philippines related to Tropical Storm Ulysses at 05:00am local time today (10 November).

In anticipation of the onset of strong breeze to near gale conditions, Tropical Cyclone Wind Signal (TCWS) #1 is now in effect over more localities in CALABARZON, Bicol Region, and Eastern Visayas. More areas in these regions will be placed under TCWS #1 in the next bulletin. TCWS #2 may be hoisted in some areas of Bicol Region as early as tonight. Based on the intensity forecast, the highest wind signal to be hoisted during the passage of Ulysses will be TCWS #3.

The tail-end of a cold front (shear line) will bring light to moderate with at times heavy rains over Cagayan including Babuyan Islands, Isabela, and Apayao. Light to moderate with at times heavy rains will also be experienced over Aurora, Quezon, Bicol Region, Eastern Visayas, Caraga, and Davao Region. Moderate to heavy rains associated with the rainbands of Ulysses will begin affecting Bicol Region and portions of Eastern Visayas tomorrow.

In the next 24 hours, rough to very rough seas (2.5 to 5.0 m) will be experienced over the entire seaboards of Northern Luzon and the seaboards of Kalayaan Islands due to the surge of the Northeast Monsoon. Ulysses will also bring rough to very rough seas (2.5 to 4.5) over the seaboards of areas under TCWS, Aurora, and northern Quezon (including the northern and eastern coastal waters of Polillo Islands) and the eastern seaboard of Eastern Samar (that are not under TCWS).

Moderate to rough seas will be experienced over the western seaboards of Central and Southern Luzon and the eastern seaboard of Mindanao.

On the forecast track, Uysses will move generally northwestward today, then turn more westward tomorrow. It is more likely to make landfall over Quezon on Thursday morning (12 November), with a close approach of Catanduanes and Camarines Norte tomorrow afternoon and evening, respectively. However, the slight shift in the orientation of the track forecast shows an increasing likelihood of landfall over Bicol Region tomorrow afternoon or evening.

Ulysses is forecast to intensity into a severe tropical storm tonight and may reach typhoon category by tomorrow morning, reaching peak intensity (140-155 km/h) tomorrow afternoon or evening. Landfall at or near peak intensity is highly likely.
