MANILA, Philippines – Severe Tropical Storm 'Siony' is now outside the Philippine Area of Responsibility (PAR) while the Low Pressure Area (LPA) east of Eastern Samar remains likely to develop into a tropical depression 'Tonyo' within the next 48 hours, state weather bureau PAGASA announced in its 5:00 am bulletin on Saturday, November 7, 2020.
'Bagyong Siony' (Atsani) left the PAR at 12:00 am today. This storm is expected to turn southwestward in the next 12 hours and head towards the West Philippine Sea. It is forecast to weaken into a Low Pressure Area within 24 to 36 hours due to increasingly unfavorable conditions.

In the next 24 hours, moderate to rough seas due to 'Siony' (2.0 to 3.0 m) will be experienced over the seaboards of Batanes, Babuyan Islands, and the northern portion of Ilocos Norte. Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.
'Bagyong Tonyo'
At 4:00 am today, the LPA was estimated at 465 km East of Surigao City, Surigao del Norte or 440 km East of Guiuan, Eastern Samar.
Potential 'Tonyo' is forecast to move west-northwest towards Eastern Visayas this morning or afternoon.
PAGASA Weather Specialist Benison Estareja announced the raising of tropical cyclone wind signal No. 1 once LPA developed into a tropical depression (possibly while in the Philippine landmass).
10pm update: At 8:00 PM tonight, the Low Pressure Area west of Sorsogon developed into Tropical Depression 'Tonyo'. Signal No. 1 will be raised over areas nearby or along the forecast track, PAGASA said.
Rainfall today
Moderate to heavy rains
Light to moderate, at times heavy, over the rest of CALABARZON, MIMAROPA, Visayas and Mindanao.
Flooding, rain-induced landslides and lahar may occur during heavy or prolonged rainfall especially in areas highly or very highly susceptible to these hazards and or those that received significant rainfall from Pepito, Quinta and Rolly, PAGASA said.
The current LPA, potential 'Tonyo', is the Philippines' 20th tropical cyclone for 2020 and second for November.
On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.
However, the weather bureau advised of more cyclones that could enter PAR until December.
PAGASA declared the onset of rainy season on June 12.
