PAGASA tracks tropical depression, monitors 2 low pressure areas with one poised for cyclone

Batanes province is experiencing scattered rain and thunderstorms from the developing low pressure area.
A system already delivering rain and thunderstorms, now poised to intensify
The low pressure area near Batanes showed high potential for cyclone development as of Thursday evening.

As September drew toward its close, the Philippine weather bureau found itself watching three simultaneous disturbances in the waters surrounding the archipelago — a reminder that the sea does not rest when the calendar grows late. The most consequential of these hovered near Batanes, the northernmost edge of the Philippines, where a low pressure area showed strong signs of becoming the season's tenth tropical cyclone and September's sixth. While two other systems posed little immediate threat to the mainland, the developing Batanes system asked the oldest question of island life: how much time remains to prepare?

  • A low pressure area near Batanes has shifted to high development probability, threatening to become Typhoon Julian — the sixth cyclone in a single September.
  • Batanes province is already absorbing the system's early effects, with scattered rain and thunderstorms unsettling the northernmost communities.
  • A separate tropical depression 2,610 kilometers east of Central Luzon carries 55 km/h winds but is unlikely to enter Philippine territory, offering some relief.
  • A third system even farther out is expected to weaken and dissipate before it can pose any meaningful threat.
  • The rest of the Philippines remains largely calm, creating a sharp divide between the battered north and the fair skies elsewhere.
  • The coming hours will determine whether Batanes faces a named typhoon requiring formal alerts and emergency readiness.

On the evening of September 26, PAGASA was tracking three weather disturbances at once, with the most pressing concern anchored near the country's northern frontier. A low pressure area sitting roughly 560 kilometers east of Itbayat in Batanes province had earned a high probability rating for cyclone development. Should it intensify as expected, it would be named Julian — and would stand as the sixth tropical cyclone to form in Philippine waters within September alone, a concentration of storm activity that underscored how relentless the season had become.

Earlier that same day, a separate system outside Philippine waters had already crossed into tropical depression status, registering maximum sustained winds of 55 kilometers per hour by 8 a.m. By evening it had drifted to 2,610 kilometers east of Central Luzon, moving slowly northwestward. PAGASA assessed its chances of entering the Philippine Area of Responsibility as low, and its distance offered some reassurance. A third system, even farther out at 1,710 kilometers east of Central Luzon, was expected to weaken and dissolve within days.

The weight of attention, then, fell on Batanes. The province was already experiencing scattered rain and thunderstorms from the developing low pressure area, while the rest of the country enjoyed mostly fair conditions. That contrast — calm skies over the mainland, unsettled weather gathering in the north — framed the essential uncertainty of the moment. For Batanes residents and those with maritime interests in the region, the hours ahead would reveal whether the system remained a rain event or grew into something demanding a more urgent response.

The Philippine weather bureau was tracking three separate weather disturbances on Thursday evening, September 26, with one of them positioned to potentially become the country's tenth tropical cyclone of the year. The most immediate concern sat near the northernmost tip of the archipelago, where a low pressure area hovering 560 kilometers east of Itbayat in Batanes province showed strong signs of intensifying into a full tropical cyclone. If that system develops as expected, it would receive the local name Julian and mark the sixth cyclone to form in Philippine waters during September alone.

Earlier that morning, a separate weather system had crossed a threshold. A low pressure area that had been forming outside Philippine territorial waters developed into a tropical depression by 8 a.m., with maximum sustained winds of 55 kilometers per hour and gusts reaching 70 kilometers per hour. By evening, this system had drifted to a position 2,610 kilometers east of Central Luzon, moving slowly northwestward at 10 kilometers per hour. The Philippine Atmospheric, Geophysical, and Astronomical Services Administration noted that despite its development, this tropical depression carried only a slim likelihood of entering the Philippine Area of Responsibility—the nation's official weather monitoring zone. Its distance and trajectory suggested it would remain a distant concern.

The third system under observation presented even less threat. Located 1,710 kilometers east of Central Luzon, this low pressure area outside Philippine waters showed only a low probability of developing into a cyclone and was expected to weaken and dissipate within days, according to PAGASA forecasters.

The real focus remained on the system near Batanes. As of 8 p.m. Thursday, PAGASA's assessment shifted the probability calculus sharply upward, declaring that the low pressure area already possessed a high chance of becoming a tropical cyclone. The system was already delivering its effects to the northernmost province, bringing scattered rain and thunderstorms across Batanes. Elsewhere across the Philippines, weather conditions remained largely stable—mostly fair skies with only isolated rain showers or thunderstorms expected in scattered locations. The contrast was stark: while most of the country enjoyed benign conditions, Batanes braced for what could be an intensifying system.

The naming convention for Philippine tropical cyclones follows a predetermined list, and if the Batanes system reached cyclone strength, it would be assigned the name Julian. This would represent a significant milestone for the 2024 typhoon season, which had already proven active. The fact that it would be the sixth cyclone in a single month underscored how concentrated the storm activity had become as the season progressed. For residents of Batanes and maritime interests in the region, the coming hours would determine whether this low pressure area remained a rain-producing system or escalated into something requiring more serious preparation and response.

Why does it matter that this system near Batanes might become the tenth cyclone of the year rather than the ninth or eleventh?

Model

It's a marker of seasonal intensity. The number itself tells you whether the year is tracking above or below historical averages. Ten by late September suggests an active season, which shapes how prepared communities stay and how resources get allocated.

Inventor

The tropical depression that formed outside Philippine waters—why mention it at all if it's unlikely to reach the country?

Model

Because people need to know what's being watched. A system that's 2,600 kilometers away and moving slowly is not an immediate threat, but it's part of the full picture. Transparency about what meteorologists are tracking, even distant systems, builds trust.

Inventor

What does "high chance of developing into a tropical cyclone" actually mean in practical terms for someone in Batanes?

Model

It means the rain and thunderstorms they're already experiencing could intensify, winds could strengthen significantly, and they should start thinking about securing loose objects and checking emergency supplies. It's the difference between a wet day and a dangerous day.

Inventor

Why does the article emphasize that most of the country has fair weather?

Model

Contrast. It shows that the threat is localized, not nationwide. It prevents panic while still taking the Batanes situation seriously. Most Filipinos can go about their day normally; Batanes cannot.

Inventor

If this becomes Typhoon Julian, what happens next?

Model

Warnings escalate. PAGASA issues tropical cyclone advisories with specific wind speeds and rainfall predictions. Coastal communities prepare for storm surge. The national disaster agency mobilizes. It shifts from weather monitoring to emergency response.
