The low-pressure area being monitored over the past few days has a high chance of developing into a tropical cyclone, which may prompt the hoisting of Storm Signal No. 1 in several areas, according to PAGASA on Monday.
The weather disturbance will be given the local name "Henry," the country's eighth tropical cyclone this year. Potential tropical depression Henry was last located 165 kilometers east-northeast of Borongan City, Eastern Samar.
Following its development, Storm Signal No. 1 will likely be hoisted in several areas, including the Bicol Region, Quezon Province, Batangas, Occidental Mindoro, Oriental Mindoro, Marinduque, and Romblon. This is due to the potential tropical cyclone's forecast track.
A yellow rainfall warning has been issued for several areas, including Sorsogon, Albay, Masbate, Northern Samar, Eastern Samar, Samar, Biliran, Leyte, Marinduque, Romblon, and Oriental Mindoro. Heavy rainfall ranging from 50 to 100 millimeters is expected in these areas within the next 24 hours.
PAGASA has also warned of possible flooding and landslides in areas prone to these hazards under the rainfall warning. The area is expected to experience heavy rainfall and increased storm activity.
PAGASA said that potential Henry may traverse Southern Luzon and the Visayas on Tuesday before emerging over the West Philippine Sea on Wednesday. This forecast track may bring significant changes to the weather in these areas.
