Let’s talk about Tropical Storm Ada (international name: Nokaen), currently located just off the east coast of Luzon, and clear up some confusion about what this system is doing, what it is not doing, and what that means for the Philippines over the next several days.
First off, yes — Ada has intensified a bit, but this does not mean it is on track to become a typhoon. In fact, the opposite is true. Ada is being strongly impacted by the Northeast Monsoon (Amihan) and an incoming cold surge, which is already shearing the system apart.
If you look at satellite imagery, you can clearly see striations in the cloud pattern, with clouds being stretched away from the center. That is a textbook sign of strong wind shear. Because of that shear, Ada has developed a very broad and uneven wind field, with most of the stronger winds and rainfall displaced well north and east of the low-level center.
This setup has caused scattered showers to spread across parts of Central and Southern Luzon, even though the storm’s center remains offshore. That does not mean the storm is moving inland — it means the monsoon is interacting with the storm, stretching moisture outward along the shear line.
Now for the good news.
A strong high-pressure system over eastern China and Siberia is pushing southward, reinforcing the Northeast Monsoon. This cold surge will continue to:
• Increase wind shear
• Inject cooler, drier air into the system
• Push Ada northward and eventually northeastward
Because of this, there is no typhoon scenario with Ada. The environment simply does not support it.
Many people have asked an important question:
“Is this storm going to loop back and hit the Philippines?”
The honest answer is yes and no, and the distinction matters.
Yes — the low-level circulation may drift back south or southwest later on once the storm stalls east of Luzon.
No — it would return as a much weaker, exposed system, with little organized convection and limited rainfall.
At that point, it would not really be a tropical storm anymore. It would be closer to a moisture surge, driven by the monsoon, rather than a true cyclone.
This is a very common January pattern in the Western Pacific. Winter storms behave very differently from October or November systems. The monsoon is dominant, wind shear is strong, and cold air frequently disrupts tropical development.
So let’s talk impacts, because that’s what actually matters.
Heaviest impacts remain focused on the east coast, especially:
• Eastern Luzon near the Sierra Madre
• Coastal areas exposed to the Philippine Sea
These areas may continue to see periods of moderate rain, gusty monsoon winds, and rough seas.
Limited impacts elsewhere:
• Manila: mostly dry with occasional monsoon clouds
• Cebu: improving conditions, only spotty showers
• Palawan: dry
• Most of Mindanao: dry to partly cloudy
This is not a widespread flooding or wind event for the country.
I also want to directly address some of the misleading graphics and posts circulating online. Some of these show dramatic looping tracks or compare Ada to historic super typhoons. That comparison is not meteorologically valid. Those past storms occurred in very different atmospheric setups, usually when the monsoon was weak or absent.
Right now, the monsoon is in full control.
Even looking ahead into the extended forecast, any future disturbance that tries to form will almost certainly:
• Run into strong shear
• Be suppressed by cold surges
• Produce rain, not a major storm
Part of my job here is not just forecasting, but also debunking misinformation so people don’t panic unnecessarily or spread false expectations.
I’ll continue monitoring Ada closely and will update you if anything meaningful changes. For now, this remains a monsoon-dominated, shear-driven system, with coastal rain impacts and no typhoon threat.
As always, please continue to follow official advisories from PAGASA, especially for marine conditions, and use common sense if you’re in flood-prone coastal areas.
Thank you to everyone who continues to support this page, share these updates, and help keep accurate weather information moving.
Most important thing, as always — stay safe out there, friends.
TAGALOG
Pag-usapan natin ang Tropical Storm Ada (internasyonal na pangalan: Nokaen) na kasalukuyang nasa silangan ng Luzon, at linawin kung ano talaga ang ginagawa ng bagyong ito — at kung ano ang hindi nito gagawin.
Oo, bahagyang lumakas si Ada, pero hindi ito nangangahulugan na magiging typhoon ito. Sa katunayan, kabaligtaran ang nangyayari. Si Ada ay malakas na naaapektuhan ng Amihan at ng papasok na cold surge, na unti-unti nang sumisira sa istruktura ng bagyo.
Sa satellite imagery, makikita ang mahahabang ulap na hinihila palayo sa sentro, malinaw na palatandaan ng malakas na wind shear. Dahil dito, malapad at hindi pantay ang wind field ni Ada, at ang ulan at hangin ay nasa hilaga at silangan ng sentro, hindi direkta sa ibabaw ng lupa.
Ito ang dahilan kung bakit may kalat-kalat na ulan sa Central at Southern Luzon, kahit offshore pa rin ang sentro ng bagyo. Ito ay epekto ng pakikipag-ugnayan ng bagyo sa Amihan, hindi paglapit ng bagyo sa lupa.
Magandang balita:
Isang malakas na high-pressure system mula China at Siberia ang bumababa pa-timog, na lalo pang nagpapalakas sa Amihan. Ang cold surge na ito ay:
• Magdadagdag ng wind shear
• Magpapasok ng mas malamig at tuyong hangin
• Magtutulak kay Ada pa-hilaga at pa-hilagang-silangan
Dahil dito, walang typhoon scenario para kay Ada.
Marami ang nagtatanong:
“Babalik ba ito at tatama sa Pilipinas?”
Ang tamang sagot ay oo at hindi.
Oo — maaaring bumalik pa-timog ang low-level circulation matapos itong huminto sa silangan ng Luzon.
Hindi — babalik ito na mahina, exposed, at halos walang ulan.
Sa puntong iyon, hindi na ito maituturing na bagyo kundi isang daloy ng moisture na dulot ng Amihan.
Ito ay karaniwang pattern tuwing Enero. Iba ang kilos ng mga bagyo sa taglamig kumpara sa peak season. Mas malakas ang Amihan, mas matindi ang wind shear, at madalas napipigilan ang paglakas ng bagyo.
Mga inaasahang epekto:
• Mas malakas na ulan sa silangang baybayin
• Mahangin at maalon sa coastal areas
Limitadong epekto sa iba pang lugar:
• Maynila: kadalasang tuyo
• Cebu: gumaganda ang lagay ng panahon
• Palawan: tuyo
• Karamihan ng Mindanao: bahagyang maulap
Hindi ito isang nationwide na bagyo.
Mag-ingat sa mga maling forecast online na nagpapakita ng dramatikong track o paghahambing sa mga super typhoon. Hindi iyon tama sa kasalukuyang atmospheric setup.
Sa ngayon, kontrolado ng Amihan ang panahon.
Patuloy akong magbibigay ng update kung may pagbabago. Sa ngayon, ito ay isang shear-dominated, monsoon-driven system, na may ulan sa baybayin at walang banta ng typhoon.
Sundin pa rin ang opisyal na abiso ng PAGASA, lalo na para sa karagatan.
Maraming salamat sa patuloy na suporta at pagbabahagi ng tamang impormasyon.
At gaya ng lagi kong sinasabi — mag-ingat po tayong lahat.
