Tropical Storm Kalmaegi to Enter Philippines as Typhoon Tino by Monday

Potential for significant flooding and landslides across nearly two dozen provinces in the Visayas and surrounding regions as the typhoon makes landfall and crosses the archipelago.
The system is expected to maintain typhoon strength throughout its passage.
Kalmaegi will remain dangerous even as it crosses the archipelago, not weakening as it moves inland.

From the open Pacific, a storm named for the seagull is winging its way toward the Philippine archipelago — a reminder that the sea, indifferent to calendars, delivers its own seasons. Tropical Storm Kalmaegi, soon to be called Tino once it enters Philippine waters on Sunday, November 2nd, is forecast to grow into a typhoon before making landfall in Eastern Visayas or Caraga by Monday evening or Tuesday morning. The communities in its path — spread across nearly two dozen provinces — now face the ancient, recurring work of preparation, vigilance, and endurance that life on this archipelago has always demanded.

  • A storm that was only a tropical depression Saturday evening has already strengthened into Tropical Storm Kalmaegi, with winds of 65 km/h and a rapid westward march toward the Philippines at 20 km/h.
  • The system is expected to double in ferocity within 48 hours — from tropical storm to full typhoon — arriving near its peak intensity of 140 km/h precisely as it strikes Eastern Visayas or Caraga on Monday night or Tuesday morning.
  • Rainfall totals of 100 to 200 millimeters are forecast for some of the most vulnerable island provinces during a single 24-hour window, raising serious alarm over flooding and landslides across nearly two dozen provinces.
  • Gale warnings and possible storm surge alerts are expected as early as Sunday morning, with Signal No. 1 wind warnings giving coastal residents a narrow 36-hour window to secure their lives and homes.
  • After cutting across the Visayas and the northern Sulu Sea, the typhoon is projected to exit Philippine waters by November 6th — but forecasters warn that Tino may be only the first of two or three major systems to threaten the country this November.

On Saturday evening, November 1st, a tropical depression organizing itself in the Pacific crossed a quiet but consequential threshold — it became Tropical Storm Kalmaegi, named for the Korean word for seagull. Tracking 1,320 kilometers east of Eastern Visayas and accelerating westward at 20 kilometers per hour, the system was already moving with intent.

When Kalmaegi enters Philippine territorial waters Sunday morning, it will be renamed Tino — a shift that is more than symbolic. It marks the moment the storm becomes the Philippines' to watch, warn about, and survive. By then, its winds will have reached 65 km/h with gusts to 80 km/h, and the intensification is far from over.

PAGASA forecasts a swift and dangerous escalation: severe tropical storm by Sunday, full typhoon by Monday, with peak winds near 140 km/h. The timing is the most troubling detail — Tino is expected to make landfall in Eastern Visayas or Caraga on Monday evening or Tuesday morning, potentially arriving at the height of its power.

The rainfall threat is immense. Seven provinces — among them Northern Samar, Leyte, and Dinagat Islands — could absorb 100 to 200 millimeters of rain in a single day. Fifteen more provinces face 50 to 100 millimeters in the same window. Flooding and landslides are already considered likely across nearly two dozen provinces.

After landfall, the typhoon is forecast to cross the Visayas, traverse the northern Sulu Sea, and exit over the West Philippine Sea by Wednesday — maintaining typhoon strength throughout. Storm surge warnings and gale advisories are expected to begin as early as Sunday. Signal No. 1 may be raised in Eastern Visayas and Caraga Sunday morning, giving communities a 36-hour window to prepare.

Tino is expected to leave Philippine waters by November 6th. It will not be the last test of the season — forecasters anticipate two or three more tropical cyclones will form or enter the Philippine Area of Responsibility before November is done.

A tropical depression churning in the Pacific east of the Philippines crossed a threshold on Saturday evening, November 1st. By 8 p.m., it had organized enough to earn an international name: Kalmaegi, a word meaning seagull in Korean. The Philippine weather service was tracking it from a distance—1,320 kilometers away from Eastern Visayas—but the system was moving with purpose, accelerating westward at 20 kilometers per hour.

When Kalmaegi crosses into Philippine territorial waters on Sunday morning, November 2nd, it will be renamed Tino, following the country's own naming convention for tropical cyclones. The transition marks more than a bureaucratic shift. It signals that the system is now the Philippines' responsibility to monitor, warn about, and prepare for. By that point, Kalmaegi will have strengthened from a tropical depression into a tropical storm, with sustained winds of 65 kilometers per hour and gusts reaching 80 kilometers per hour—a 10 kilometer-per-hour jump in just hours.

The forecast trajectory shows rapid intensification ahead. The Philippine Atmospheric, Geophysical, and Astronomical Services Administration expects Kalmaegi to become a severe tropical storm by Sunday and a full typhoon by Monday morning or afternoon, November 3rd. The system is predicted to reach peak intensity around 140 kilometers per hour, though forecasters cautioned that this figure could shift in coming updates. More concerning than the speed of strengthening is the timing: the typhoon is expected to make its first landfall in Eastern Visayas or Caraga on Monday evening or Tuesday morning, November 4th, potentially arriving at or near its maximum power.

The rainfall outlook reveals the scale of the threat. From Sunday evening through Monday evening, ten provinces across the eastern Visayas will face moderate to heavy rain, with 50 to 100 millimeters expected. The heaviest downpour comes next: Monday evening through Tuesday evening, when Northern Samar, Eastern Samar, Samar, Leyte, Southern Leyte, Biliran, and Dinagat Islands could receive 100 to 200 millimeters of rain. Another fifteen provinces will experience 50 to 100 millimeters during the same window. The weather service has already flagged the likelihood of flooding and landslides across nearly two dozen provinces in the path.

After making landfall, Kalmaegi is forecast to traverse much of the Visayas, cross the northern Sulu Sea and northern Palawan, and emerge over the West Philippine Sea by Wednesday morning or afternoon, November 5th. A close approach to the Kalayaan Islands on Wednesday is also possible. Throughout this journey, the system is expected to maintain typhoon strength. Coastal communities face additional hazards: gale warnings are anticipated as early as Sunday morning, with very rough seas or worse affecting the northern, western, and eastern seaboards of Luzon, and the eastern coasts of the Visayas and Mindanao. Storm surge warnings may begin Sunday as well, with coastal flooding possible in vulnerable areas.

The weather service is already preparing the public. Signal No. 1, the lowest tropical cyclone wind signal, may be raised in Eastern Visayas and Caraga as early as Sunday morning or afternoon, giving residents 36 hours to secure their homes and prepare. The system is expected to exit Philippine waters by Thursday, November 6th. Looking ahead, the weather bureau anticipates two or three additional tropical cyclones will either form or enter the Philippine Area of Responsibility during November, suggesting this is only the first major test of the season.

Rapid intensification is not ruled out before initial landfall

Why does the name change when it enters Philippine waters? Is that just tradition, or does it serve a practical purpose?

Model

It's both. Kalmaegi is the international designation—that's what meteorologists worldwide call it. But when it enters the Philippine Area of Responsibility, the local weather service takes the lead on forecasting and warnings, so they use their own name. It helps the public anchor the threat to their own system, their own warnings. Tino becomes the name people hear on local radio and television.

Inventor

The forecast mentions "rapid intensification is not ruled out." What does that mean for people on the ground?

Model

It means the system could become more dangerous faster than the current models predict. A typhoon that reaches 140 kilometers per hour is serious. One that reaches 160 or 180 would be catastrophic. The uncertainty is real, which is why forecasters keep saying these numbers may change.

Inventor

The rainfall numbers—100 to 200 millimeters in some places—how does that translate to actual danger?

Model

That's roughly four to eight inches of rain in 24 hours. In mountainous terrain, which much of the Visayas is, that volume of water moving downslope becomes a landslide risk. In low-lying areas, it's flooding. The concern isn't just the rain itself but where it goes and how fast it moves.

Inventor

Why is the timing of landfall so important if the system is going to be a typhoon either way?

Model

Because landfall at peak intensity means maximum wind damage, maximum storm surge, maximum everything happening at once. If the system weakens before it hits land, the damage is less severe. If it hits while still strengthening, the destruction compounds.

Inventor

The forecast shows it crossing multiple islands and emerging over the West Philippine Sea. Does that mean it's done threatening the Philippines?

Model

Not entirely. It could still affect western Luzon and Palawan as it crosses. And if it re-intensifies over warm water, it could pose a threat to other areas. But yes, once it's over the sea and moving away, the immediate danger to populated areas diminishes.
