‘Bising’ may re-enter PAR before weakening over China

Tropical Storm “Bising” is expected to move slowly north over the sea west of extreme Northern Luzon, then shift north-northeast, with a possibility of brief re-entry to the Philippine Area of Responsibility (PAR) by Monday.

State weather bureau Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on 5 July reported that “Bising” is forecast to intensify into a severe tropical storm in the next 24 hours as it approaches Taiwan strait, but is projected to weaken by Tuesday upon interacting with the landmass of Eastern China.

As of 10 a.m., Saturday, “Bising” was estimated 406 kilometers west of Basco, Batanes, with maximum sustained winds of 75 kilometers per hour.

Although no tropical storm signals have been raised, PAGASA warned of rough to moderate sea conditions across the northern and western seaboards of Northern Luzon. Along the seaboard of Batanes and western coasts of Ilocos Norte and Babuyan Islands, wave heights of up to three meters may occur.

Likewise, wave heights ranging from 2 to 2.5 meters may be expected in the north-western seaboard of Ilocos Sur, the rest of Ilocos Norte, and the western shores of La Union, Pangasinan, and Zambales.

“Mariners of motorbancas and similarly-sized vessels are advised to take precautionary measures while venturing out to sea and, if possible, avoid navigation under these conditions,” PAGASA advised.

Meanwhile, the Municipality of San Juan, La Union has declared the temporary closure of all beaches and suspension of water-related activities starting Saturday, 5 July amid heightened weather risks posed by “Bising” and the southwest monsoon.

The executive order, signed by Mayor Mairiquita Padua Ortega, was based on the recommendations of the Municipal Disaster Risk Reduction and Management Council and in response to the weather bulletins issued by PAGASA. The tropical depression, expected to bring heavy rains and strong winds over Northern Luzon, threatens the western seaboard including La Union with moderate to rough sea conditions and waves reaching up to 2.0 meters.

According to the order, the law enforcement agencies are tasked to enforce the closure in all coastal barangays to prevent potential accidents involving tourists, swimmers, surfers, and small sea vessels.

The local government emphasized that the order will remain in effect until further notice and urged the public to avoid coastal activities for their safety. The Executive Order was signed and made effective on 4 July 2025.
