Severe Tropical Storm Bising (Danas) has maximum sustained winds of 110 km/h as of Saturday evening, July 5. Sea travel is risky for all vessels in the Batanes-Babuyan Islands area.

MANILA, Philippines – Bising (Danas) intensified from a tropical storm into a severe tropical storm at 8 pm on Saturday, July 5, as it continued its generally slow movement outside the Philippine Area of Responsibility (PAR).

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said in its 11 pm advisory that Bising now has maximum sustained winds of 110 kilometers per hour from 85 km/h in the afternoon. Its gustiness is now up to 135 km/h from 105 km/h.

Bising is already projected to reach typhoon category on Sunday, July 6. Under the weather bureau’s classification system, a typhoon has maximum sustained winds of 118 to 184 km/h.

As of 10 pm on Saturday, Bising was located 410 kilometers west of Basco, Batanes, moving northeast at only 10 km/h.

Its trough or extension is still bringing scattered rain and thunderstorms to Batanes and Babuyan Islands.

PAGASA also issued a gale warning for the northern seaboard of Northern Luzon. Here are the expected sea conditions in the next 24 hours:

Up to very rough seas (travel is risky for all vessels)

• Seaboard of Batanes; western seaboard of Babuyan Islands – waves up to 4.5 meters high

Up to rough seas (small vessels should not venture out to sea)

• Western seaboard of Ilocos Norte – waves up to 3.5 meters high

Up to moderate seas (small vessels should take precautionary measures or avoid sailing, if possible)

• Northwestern seaboard of Ilocos Sur; remaining seaboards of Ilocos Norte – waves up to 2.5 meters high
• Western seaboards of La Union, Pangasinan, and Zambales; remaining seaboard of Ilocos Sur – waves up to 2 meters high

Bising had left PAR at 12 pm on Friday, July 4, around 10 hours after developing. However, it began recurving toward PAR on Saturday.

Bising is expected to maintain its northeast direction in the next 72 hours, and may “briefly pass the northwestern boundary of PAR” — the Taiwan area — between Sunday evening and Monday morning, July 7. Taiwan is within PAR.

PAGASA added that Bising could start weakening as it passes over the Taiwan Strait. It may just be a low pressure area by Thursday, July 10, “as it interacts with the landmass of Eastern China.”

Bising was the Philippines’ second tropical cyclone for 2025 and the first for the month of July.

PAGASA expects 11 to 19 tropical cyclones to form within or enter PAR in the second half of 2025. These are the weather bureau’s estimates per month:

• July – 2 or 3
• August – 2 or 3
• September – 2 to 4
• October – 2 to 4
• November – 2 or 3
• December – 1 or 2

Meanwhile, the southwest monsoon or habagat is still affecting much of the country, especially the Ilocos Region, Zambales, and Bataan, which are dealing with occasional rain.

Scattered rain and thunderstorms are also hitting Metro Manila, Calabarzon, Mimaropa, the Cordillera Administrative Region, the rest of Cagayan Valley, the rest of Central Luzon, Western Visayas, and Mindanao, while isolated rain showers or thunderstorms are possible in Bicol and the rest of the Visayas. – Rappler.com
