When a typhoon, earthquake or heavy rain hits, will your parcel be delayed?
Can typhoons, earthquakes or heavy rain delay HowBridge parcels?
They may, which is why HowBridge notifies you proactively. Since 2026-10-02, HowBridge reads public data from the Central Weather Administration, the Water Resources Agency and the Directorate-General of Personnel Administration every 5 minutes. When a typhoon's forecast radius of Beaufort force-7 winds will sweep over Taiwan within 72 hours, an earthquake reaches seismic intensity 5-lower or above, an extremely torrential rain advisory or higher is issued, a level-1 flood warning is in effect, or work and school are suspended, a notification is sent after HowBridge staff review it (work and school suspensions are sent automatically once detected). If the disaster affects Taoyuan International Airport (Dayuan District), the Port of Taipei or the Port of Keelung, everyone's consolidation shipments may be delayed, so all active members are notified; otherwise only members whose delivery address is within the affected area are notified. Each person receives only one message, sent in this order: app push notification, browser notification, Email, LINE. For actual shipment status, please rely on the member center.
This is a HowBridge service notification for consolidation members, reminding you that parcels may be delayed. It includes the name of the disaster, the areas that may be affected, and how many of your parcels are currently in transit. It is not a government disaster alert: the national alerts that sound on your phone are sent by the government, and for evacuation and work or school suspensions you should follow government announcements. HowBridge only offers China→Taiwan consolidation shipping, and its only warehouses are the Shenzhen consolidation warehouse and the Taoyuan Dayuan operations warehouse. A notification does not mean your parcel will definitely be delayed, and it does not guarantee a delivery time. HowBridge only reads public government data and has no partnership with, or endorsement from, any of the agencies.
Which official government data does HowBridge use?
Every notification decision is based on public government data; HowBridge does not make its own weather forecasts. These are the data sources actually read:
| Disaster | Data source | What HowBridge reads |
|---|---|---|
| Typhoon | Central Weather Administration open data: typhoon track forecast | Latest analyzed position, forecast positions for the next 72 hours, and the radius of force-7 winds |
| Earthquake | Central Weather Administration open data: significant felt earthquake report, small-area felt earthquake report | Origin time, magnitude, and the maximum seismic intensity in each county or city |
| Heavy rain | Central Weather Administration open data: weather advisories (by county and city) | Currently active heavy rain, torrential rain, extremely torrential rain and super torrential rain advisories in each county or city |
| Flood | Water Resources Agency Flood Prevention Information Service | Areas and levels of flood warnings |
| Work and school suspension | Directorate-General of Personnel Administration: work and school suspension due to natural disasters | Whether each county or city has suspended work or school today or tomorrow, including cases where only some townships are suspended |
How often is it checked?
The system reads the data every 5 minutes. Each time the typhoon forecast is updated, notifications that have not yet been sent switch to the latest forecast area.
How is the Weather Administration open data obtained?
On 2026-09-22, HowBridge applied for an authorization code from the Central Weather Administration Open Data Platform and uses it to read the datasets above. As required by the platform's terms of use, the attribution is:
Provider: Central Weather Administration, Ministry of Transportation and Communications — Typhoon News and Warnings: Tropical Cyclone Tracks
Provider: Central Weather Administration, Ministry of Transportation and Communications — Weather Advisories: Current Advisory Status for Each County and City
Provider: Central Weather Administration, Ministry of Transportation and Communications — Weather Advisories: Content and Affected Areas of Each Advisory
Provider: Central Weather Administration, Ministry of Transportation and Communications — Significant Felt Earthquake Report
Provider: Central Weather Administration, Ministry of Transportation and Communications — Small-Area Felt Earthquake Report
Provider: Central Weather Administration, Ministry of Transportation and Communications — Tide Forecast: 1-Month Tide Forecast
This open data is released to the public under the Open Government Data License.
What if the data cannot be fetched?
If one source is temporarily unavailable, the other sources are still checked as usual. In that case there will be no notification for that type of disaster, so please follow government announcements.
When are notifications sent, and why not for every rainfall?
Too many notifications can make people stop reading them. So HowBridge set higher thresholds of its own, with reference to how the government describes each grade, and only notifies you in situations that may affect consolidation shipping:
| Disaster | HowBridge notification threshold | Why this level was chosen |
|---|---|---|
| Typhoon | On the Weather Administration's forecast track, the radius of Beaufort force-7 winds will cover a township in Taiwan within the next 72 hours | HowBridge looks at the forecast track to notify you early instead of waiting for a warning; one point per hour is interpolated between forecast points so that a wind radius passing between them is not missed |
| Earthquake | Seismic intensity 5-lower or above in any county or city, counting only reports from within 3 hours of the quake | The Weather Administration describes level 4 as including a few objects toppling, possible minor damage, and power or water possibly cut in very few areas; 5-lower means cracks in some walls and power, water, gas or communications possibly cut in a few areas. HowBridge chose 5-lower as its threshold |
| Heavy rain | An extremely torrential rain or super torrential rain advisory in any county or city | Extremely torrential rain is accumulated rainfall of 350 mm or more in 24 hours, or 200 mm or more in 3 hours; super torrential rain is 500 mm or more in 24 hours |
| Flood | Water Resources Agency level-1 flood warning | The Water Resources Agency explains that level 1 means roads may flood within 1 hour and level 2 means flooding may occur within 3 hours; level 2 does not trigger a notification |
| Work and school suspension | In the work and school suspension information compiled by the Directorate-General of Personnel Administration, any county, city or township that has suspended work or school | The decision is made by the county or city head (or the township or district head they authorize) based on wind, rainfall, or interruptions to traffic, water and power, and it usually means the area has been hit or is at risk of being hit. Deliveries may be affected, so a notification is always sent. Whether private logistics companies operate is up to each company |
By regulation, the Weather Administration issues a sea typhoon warning 24 hours and a land typhoon warning 18 hours before the radius of force-7 winds may arrive. HowBridge also looks at the Weather Administration's forecast track (the next 72 hours) so you can arrange receiving or adjust shipping earlier. Forecasts change with every update, so for actual impact please follow Weather Administration announcements.
Who gets notified, and will people with no parcels be bothered?
There are two notification scopes, decided by the location affected by the disaster and the Taiwan delivery address you entered in the member center:
| Location affected by the disaster | Who receives it | Reason |
|---|---|---|
| Taoyuan International Airport (Dayuan District), Port of Taipei (Bali District) or Port of Keelung | All active members | These are key import hubs, and HowBridge's Taoyuan operations warehouse is also in Dayuan District. Under the Taiwan International Ports Corporation typhoon operating guidelines, the departure time of vessels in the port area is decided at least 6 hours before the radius of force-7 winds is due to arrive, so everyone's parcels may be delayed |
| Other counties, cities or townships | Members whose delivery address is within the affected area | Only Taiwan-side deliveries in that area are affected, and deliveries elsewhere are usually not |
How is a delivery address converted into a location?
HowBridge uses the Taiwan delivery address the member has entered. Most addresses have already been matched to coordinates through the Ministry of the Interior's TGOS address matching; for those that cannot be matched, the center point of the township or district is used as an estimate, and the error depends on the size of the district and may reach several kilometers or more. See the TGOS address verification guide for details.
What if I haven't entered a delivery address?
Notifications that affect Taoyuan International Airport, the Port of Taipei or the Port of Keelung go to all members. For notifications that only affect other areas, the system cannot tell where you are, so you will not receive them (when the airport or ports are affected, all active members receive the notification). We suggest entering your delivery address in the member center first.
If the area expands, will I be notified again?
The area of heavy rain, flood and work and school suspension notices often keeps growing. A member who has already received the same type of notification within the past 24 hours will not receive another one because the area expanded; only members in the newly added areas are notified.
Typhoon: the delivery address falls within the forecast radius of force-7 winds. Earthquake and heavy rain: the county or city of the delivery address matches an affected county or city; if the area includes Taoyuan City, New Taipei City or Keelung City, the airport or ports are treated as affected and all active members are notified. Flood: the delivery address is within 10 km of the center point of a township under a flood warning. Work and school suspension: when a whole county or city suspends work, members in that county or city are notified; when only some townships are suspended, only members whose delivery address is in those townships are notified.
Where will I receive the notification, and will I get the same one several times?
No, each notification reaches each person only once. The system finds the first channel you can receive on, in order, and only moves to the next one if the previous one is not available:
| Order | Channel | What you need to do first |
|---|---|---|
| 1 | HowBridge app push notification (iPhone, Android) | Install the HowBridge app, log in and allow notifications |
| 2 | Browser notification | Turn on browser notifications under "Notification settings" in the member center; on iPhone, first add HowBridge to the Home Screen using Safari |
| 3 | Your member account has a valid Email | |
| 4 | LINE official account | Link your HowBridge LINE official account and add it as a friend |
Why does Email come before LINE?
The LINE official account has a limited monthly message quota, and HowBridge saves it for notices that need your action, such as customs agent authorization and bills, so disaster notifications use Email first. Email also has a daily sending limit; when it is used up, the remaining members are notified through LINE.
What does the notification contain?
The name of the disaster, the areas that may be affected, how many of your parcels are currently in transit, and "please rely on the member center for the latest shipment status."
Members linked through a LINE group
If you receive notifications through a LINE group, the group receives only one message, and it does not include anyone's parcel count or address.
How is flood likelihood judged, and are tides and reservoir releases notified too?
Tides, river water levels and reservoir releases never trigger a notification by themselves. They are only used, during heavy rain or flooding, to judge "how likely flooding is in this area", to help HowBridge staff decide whether to send a notification:
| Reference data | How it is used | Source |
|---|---|---|
| Flood sensors | A sensor within 10 km of the event location detects water 10 cm deep or more | Water Resources Agency |
| River water level alerts | A nearby river gauge reaches its alert water level | Water Resources Agency |
| Reservoir releases | A reservoir is releasing water and the affected downstream townships are within the area | Water Resources Agency |
| Rain gauge alerts | A nearby rain gauge reaches its alert value | Water Resources Agency |
| Tides | Coastal areas during a spring tide, with high tide within 2 hours before or after | Central Weather Administration tide forecast |
How is the result labeled?
Depending on how many of the items match, it is labeled high, medium or low, and written on the draft notification for HowBridge staff. It does not affect who receives the notification. This is an internal HowBridge reference judgment, not an official forecast.
What do members need to do to receive notifications?
Complete these 4 steps and you will receive notifications when a disaster occurs:
1Enter your Taiwan delivery address
Add or confirm a delivery address in the member center. Notifications that affect only some areas rely on the delivery address to tell where you are.
2Turn on app or browser notifications
Install the HowBridge app and allow notifications; if you don't use the app, turn on browser notifications under "Notification settings" in the member center. If push notifications don't arrive, see App notification troubleshooting.
3Confirm your Email or link LINE
If there are no app or browser notifications, the notice is sent by Email or LINE instead; please make sure your account's Email is valid, or link the HowBridge LINE official account.
4Check your shipment status after receiving a notification
Check the latest status of your in-transit parcels in the member center; to change the delivery time or address, please contact customer service. For status explanations, see Consolidation shipment status guide.
What are the limits of this notification system?
To avoid both false alarms and missed alerts, please understand these limits first:
Sent after staff review
Except for work and school suspensions, every notification is sent only after HowBridge staff review it, to avoid false alarms caused by abnormal data, so it may arrive a little later than the government announcement. Work and school suspensions are official government announcements and are sent automatically once detected.
Forecasts change
A typhoon track is a forecast, and its area changes with every update. A notification reminds you that your parcel may be delayed; it does not mean it will definitely be delayed.
Areas are estimates
Weather Administration advisories and seismic intensities are issued by county and city, and HowBridge judges the area on that basis; when a delivery address has no precise coordinates, the center point of the district is used as an estimate. The thresholds and areas are set by HowBridge and are not government regulations.
Does not replace government alerts
For personal safety, please follow national alerts and announcements from the Central Weather Administration and local governments. HowBridge's notifications only cover consolidation-related information, do not use the government's alert signals, and relay disaster names and levels from official data without making forecasts of their own (the high, medium or low flood likelihood is only an internal reference for HowBridge staff).
What research can serve as background for disaster warnings and notifications?
The studies below provide background; none of them is about HowBridge, and none can prove whether an individual parcel will be delayed:
- Typhoons and ports: Verschuur et al. (2020) analyzed port disruptions from 141 natural-disaster events, with a median of 6 days, and in all the events analyzed several ports were affected at the same time; Zhang and Lam (2015) estimated port disruption losses from extreme wind events such as typhoons at the ports of Shanghai and Ningbo, and in 2016 estimated industry cluster losses using the Port of Shenzhen. This page found no quantitative studies on how typhoons affect Taiwan's air cargo and last-mile delivery.
- Early warning: the 2019 report of the Global Commission on Adaptation estimates that a 24-hour warning before a storm can reduce losses by 30%; Hallegatte (2012) estimated that weather and early warning services in Europe avoid hundreds of millions to billions of euros in asset losses each year. Both are estimates, not studies on consolidation shipping.
- Will too many notifications go unread: the U.S. tornado study by Simmons and Sutter (2009) found that more false alarms mean higher expected fatalities (false alarms are not the same as notification frequency); Sutton and Wood (2025) point out that sending frequency and relevance cause warning fatigue. But Lim et al. (2019) argue that this concern may be overstated, and the research community has not reached a conclusion.
- Sending only to relevant people: a 2013 U.S. National Research Council workshop report says that the less precise the geographic targeting, the more likely recipients are to ignore or unsubscribe from alerts.
- Taiwan's disaster alerts: Wu et al. (2022) evaluated Taiwan's public warning cell broadcast service; a 2018 e-newsletter from Taiwan's National Science and Technology Center for Disaster Reduction estimated that about 45% of the public had received a disaster alert (2017 data) and recommended also sending by Email, apps and other channels; the Central Weather Bureau's 2009 earthquake early warning system could issue a report in about 20 seconds (Hsiao et al., 2009). Chen (2024) analyzed 1,840 typhoon work and school suspension decisions.
- Added value from open data: Magalhaes and Roseira (2020) analyzed 178 U.S. companies using government open data and identified 12 business models.
What do common disaster notification terms mean?
- Radius of Beaufort force-7 winds
- The area from the typhoon center outward to where the average wind speed is 14 meters per second (force 7); the Weather Administration marks the force-7 wind radius in its track forecasts.
- Typhoon track forecast
- The Weather Administration's prediction of a typhoon's future positions, updated with every bulletin.
- Seismic intensity
- How strongly the ground shakes at a given place during an earthquake. Since 2020-01-01 the Weather Administration has used a scale of 0 to 7, with levels 5 and 6 each divided into lower and upper.
- Extremely torrential rain
- Accumulated rainfall of 350 mm or more in 24 hours, or 200 mm or more in 3 hours.
- Super torrential rain
- Accumulated rainfall of 500 mm or more in 24 hours.
- Level-1 flood warning
- The first level of flood notices issued by the Water Resources Agency, meaning roads may flood within 1 hour; level 2 means flooding may occur within 3 hours. It is a different system from the "level 1" of river alert water levels.
- Work and school suspension
- Decided by the mayor of a special municipality or the magistrate or mayor of a county (city) under the Regulations on Work and School Suspension in Natural Disasters, who may authorize district or township (town, city) heads to decide; compiled and published by the Directorate-General of Personnel Administration. Whether private companies work depends on labor-management agreement.
- Browser notification
- A notification a website sends to your browser after you agree, with no app needed; on iPhone, first add the website to the Home Screen.
- National alert
- A disaster warning that the government sends to phones through telecom operators; it is a different system from HowBridge's service notifications.
