PAGASA
As of now, PAGASA has not identified any new low-pressure areas or tropical cyclones within or near the Philippine Area of Responsibility. However, the agency has noted that conditions could lead to the formation of low-pressure systems later in the week.
September is typically a month where the Philippines experiences several tropical cyclones, with PAGASA expecting two or three to develop this month. The next names on the list for local storms are Queenie, Rosal, and Samuel.
