Rainfall Warning Metro Manila: Alerts & Safety Tips
Rainfall warnings in Metro Manila help you understand the risk of flooding and decide what to do next, whether you are at home, at work, or traveling nearby. PAGASA (The Philippine Atmospheric, Geophysical and Astronomical Services Administration) uses three warning colors: yellow, orange, and red. This guide explains what each level means, where to check official updates, how to respond, and how to prepare essential backup power before severe weather disrupts your day.
Key Takeaways
PAGASA’s rainfall thresholds: yellow 7.5–15 mm/hour, orange 15–30 mm/hour, and red above 30 mm/hour.
Yellow means be alert, orange means be prepared, and red means take action.
Warnings generally update every three hours. Check the bulletin’s timestamp, affected areas, and next update.
Class suspensions follow automatic rules and local decisions. Check school and LGU announcements.
Heavy rain can disrupt power. Charge essential devices early and plan your backup needs.
What Do the Rainfall Warning Colors Mean?
PAGASA’s heavy rainfall warnings use three colors to communicate rainfall intensity and flood risk, based on real-time monitoring and the expected development of rain. Each color signals a different level of urgency, as shown below. Check whether your city or municipality is covered, and follow local flood reports and evacuation instructions, because conditions can vary between neighborhoods.
Warning Color | Rainfall Rate | Official Meaning | What You Should Do |
Yellow | 7.5–15 mm per hour | Flooding is possible in flood-prone areas | Be alert: monitor updates and avoid flood-prone routes |
Orange | 15–30 mm per hour | Flooding is threatening | Be prepared: avoid travel, secure your home, charge devices |
Red | More than 30 mm per hour | Severe flooding is expected | Take action: move to higher ground or evacuate if advised |

Weather Advisory vs. Heavy Rainfall Warning
PAGASA’s weather advisories and heavy rainfall warnings serve different purposes. A weather advisory helps you prepare for expected rainfall over a broader area, while a heavy rainfall warning supports immediate decisions as local conditions develop. Read the rainfall period and affected locations carefully: the totals in these two products are not directly interchangeable.
Feature | Weather Advisory | Heavy Rainfall Warning |
What it measures | Forecast rainfall totals for the stated periods, commonly shown in 24-hour windows | Rainfall intensity and near-term flood risk, informed by real-time monitoring |
Color thresholds | Yellow 50–100 mm, orange 100–200 mm, red over 200 mm | Yellow 7.5–15 mm, orange 15–30 mm, red over 30 mm |
Update rhythm | Follow the next issue time stated in the advisory | Generally every three hours; follow the next issue time stated in the bulletin |
Main purpose | Give local governments time to prepare | Tell communities to respond immediately |

Where to Check the Metro Manila Rainfall Warning Today
To check today’s rainfall warning for Metro Manila, start with PAGASA’s official channels. Confirm the bulletin’s date and issue time, then check whether your city or municipality is included. Bookmark these sources as part of your preparations for the rainy season.
PAGASA’s National Capital Region forecast page: check regional forecasts, heavy rainfall warnings, and thunderstorm information.
PAGASA’s official Facebook and X channels: read the full bulletin and check its timestamp before relying on a shared screenshot.
TV and radio: major networks relay every new warning, and a battery radio still works in a brownout.
Your city or barangay disaster office (DRRMO): local flood reports, class suspensions, and evacuation advisories.
A search for "rainfall warning today Metro Manila" will also surface weather apps and news sites, and those are useful extras. Just remember that apps like AccuWeather do not issue Philippine warnings. For any decision about travel, school, or evacuation, follow PAGASA and your LGU.
What to Do at Each Rainfall Warning Level
Use each warning as a prompt to check local conditions and take the appropriate precautions. If flooding develops or your LGU issues an evacuation order, act without waiting for the next PAGASA bulletin.
Yellow Rainfall Warning: Be Alert
Check whether your route home passes flood-prone streets or underpasses before leaving.
Allow extra travel time, since jeepneys, buses, and trains slow down in heavy rain.
Charge your phone and keep a small flashlight and rain gear in your bag.
If your street floods easily, lift valuables and appliances off the floor now.
Orange Rainfall Warning: Be Prepared
Skip non-essential trips. Flooding is threatening, and water can rise within an hour.
Charge phones, power banks, and backup batteries while electricity is available.
Secure outdoor items before conditions become dangerous. Clear drains in advance only when it is safe to do so.
Ready your go bag and know the route to your barangay's evacuation area.
Red Rainfall Warning: Take Action
Stay indoors and move to the highest safe part of your home if water enters.
Evacuate immediately when your LGU orders it, and bring your go bag and documents.
Never walk or drive through floodwater. Calm-looking water can hide open manholes and strong currents.
If flooding is approaching, switch off the main breaker before water enters your home, but only if you can reach it safely while staying dry. Never enter floodwater to operate electrical equipment.
Who Announces Class and Work Suspensions?
PAGASA issues weather warnings, while education rules and local decisions determine class arrangements. Automatic suspension provisions apply to covered public-school classes under orange and red rainfall warnings, so a separate mayoral announcement is not always required. A suspension of face-to-face classes may also come with alternative learning instructions.
Check your school’s official notice and your LGU’s announcements for the arrangements that apply to you. Private schools, colleges, and universities may follow different policies. For work, follow the relevant government announcement or your employer’s instructions rather than assuming that a school suspension also applies to your workplace.
Staying Safe in Metro Manila Floods
Flood conditions can vary from one neighborhood to the next, even under the same rainfall warning. Before deciding whether to travel or stay home, check your barangay’s updates and consider how quickly conditions around you are changing.
On the Road and in Floodwater
Avoid flooded roads, underpasses, and low-lying routes. Water can hide open drains, debris, and strong currents, so do not walk or drive through it. If a route is blocked, turn back and find a safe alternative. If you become stranded, contact local emergency responders and follow their instructions rather than attempting to cross rising water.
At Home: Electrical and Water Safety
Move appliances and essential supplies above potential flood levels before water arrives. Unplug appliances only while you and the surrounding area are dry, and stay away from fallen power lines. Report electrical hazards to Meralco or your barangay. Keep backup batteries and their connections in a dry, secure location away from floodwater. Follow your water provider’s drinking-water advisories and local health guidance for cleaning flooded rooms.
How to Keep Your Home Powered During Heavy Rain
Prepare for possible outages while electricity is still available. Charge essential devices, check your flashlights, and decide what you need to keep running if heavy rain disrupts power into the evening.
Build your emergency power supply plan around essential loads such as communication devices, lighting, refrigeration, and fans. If someone depends on powered medical equipment, arrange a dedicated backup plan with their care provider and equipment supplier.
A portable power station can supply compatible appliances indoors without combustion exhaust. Keep it dry and follow the manufacturer’s operating limits. Fuel-powered generators must remain outdoors, well away from doors, windows, and vents.
How to Estimate Backup Power Runtime
Once you know which devices you need, estimate how long a battery could support them. Use their combined average power consumption if you plan to run them together:
Estimated runtime (hours) = Battery capacity (Wh) × assumed usable-energy factor ÷ average load (W)
For example, assuming 85% of stored energy is available to the appliance, a 1024Wh battery provides about 870Wh. That would run a single fan averaging 60W for roughly 14 hours.
Treat this as a planning estimate. Actual runtime depends on conversion losses, the power station’s own consumption, battery condition, and appliance behavior. Adding devices increases the combined load and shortens runtime. Also, keeping a router powered will not restore internet service if your provider’s network is down.
EcoFlow Power Station Picks for the Rainy Season

When heavy rain interrupts the grid, it can also power selected essentials, such as a refrigerator and a fan, within its output and battery capacity limits.
Conclusion
Rainfall warnings in Metro Manila help you decide when to monitor conditions, prepare, and take action. Check PAGASA’s latest bulletin for your area and follow local flood and evacuation instructions. Preparing before severe weather arrives gives you time to focus on what your household needs. Keep a three-day emergency kit ready, agree on a family meeting plan, and plan backup power for essential lighting, communication, and refrigeration.
FAQs
Does a Rainfall Warning Apply to All of Metro Manila?
Check the locations listed in the bulletin. A warning may cover Metro Manila broadly or identify specific cities and municipalities. Flood conditions can also differ between neighborhoods, so check your barangay’s updates before deciding whether a route is safe.
Which Areas in Metro Manila Flood Most Easily?
Flooding concentrates in low-lying areas near rivers and estuaries. The most frequently affected are the CAMANAVA cluster (Caloocan, Malabon, Navotas, and Valenzuela) and communities along the Pasig and Marikina river basin. If you live in or commute through these zones, treat every yellow warning as an early heads-up.
What Health Risks Come With Floodwater in Metro Manila?
Floodwater can carry leptospirosis bacteria, so avoid wading, cover any wounds, and wash thoroughly after contact. Standing water after the rain breeds mosquitoes that spread dengue, and contaminated water can cause stomach infections. See a doctor promptly if you develop fever or muscle pain within days of flood exposure.
