Typhoon Bavi advances towards Taiwan with forecast of 700 mm of rain and destructive winds
The approach of Typhoon Bavi has placed Taiwan authorities on maximum alert due to the forecast of severe weather conditions for the coming days. The Central Meteorological Administration of the Asian territory issued bulletins indicating that the system will make landfall this Thursday morning, bringing with it a high destructive potential. Climate models project rainfall accumulations that could reach an impressive 700 millimeters in just 24 hours. This rainfall volume represents an imminent risk for the island’s urban and rural infrastructure.
The phenomenon is already demonstrating its strength through the external instability bands, which have begun to cause continuous precipitation in several coastal provinces. Historically, the island’s mountainous geography, located in one of the most active ocean basins in the world, amplifies the effects of storms of this magnitude. The combination of steep slopes and soggy ground turns heavy rain into rapid, dangerous landslides. Experts point out that the expected amount of water exceeds the monthly average for the wettest areas of tropical countries, requiring a quick response from emergency services and local rescue forces.
Forecast indicates historical volume of precipitation in mountainous areas
The most critical period for water accumulation will occur between the early hours of Thursday and the early hours of Sunday. During this weather window, the highlands of New Taipei, Taoyuan, Hsinchu and Miaoli are expected to record between 500 and 700 millimeters of rain. This extreme concentration of moisture in the soil quickly saturates natural barriers, raising the level of alert for geological disasters in communities far from large urban centers, where rescue is often more complex.
In lowland areas, the situation also requires strict caution on the part of residents and public administrators. Densely populated cities such as the capital Taipei, as well as New Taipei, Taoyuan and the counties of Hsinchu, Miaoli and Yilan, await volumes exceeding 300 millimeters. Urban drainage systems often collapse with this rate of precipitation, resulting in flash floods that block main roads, destroy vehicles and invade homes and businesses at street level.

Hurricane-force winds force essential services to shut down
In addition to abundant water, the frontal system carries gusts of wind capable of causing significant structural damage across much of Taiwanese territory. Exceptions made only to the counties of Kinmen, Chiayi and Nantou, the rest of the island will experience a drastic intensification in air currents from Wednesday night. The coastal areas of New Taipei, Green Island, Orchid Island and Lienchiang County are in the path of the most violent gusts, which can reach level 13 on the local measurement scale, strong enough to uproot trees and knock down power poles.
The Taiwanese government has strict guidelines for suspending work and educational activities during extreme weather events, aiming to minimize human exposure to danger. The mandatory shutdown comes into force whenever average sustained winds reach level 7 or when gusts exceed level 10. For this Thursday afternoon, between 12pm and 6pm, the expectation is that most districts will exceed these limits. This will force the preventive closure of schools, businesses, industrial centers and public offices, generating a momentary economic impact, but strictly necessary to protect citizens.
Regions at maximum risk and mapping of local storms
The distribution of moisture brought by the tropical cyclone will affect practically the entire territorial extension, with variations in intensity depending on the topography of each region. Forecasters have detailed how the storm will behave in different provinces, allowing for more targeted planning by rescue teams and ambulance fleets. The risk map released by the authorities includes the following specific projections:

- Localized torrential rains will hit the mountains of New Taipei, Taoyuan, Hsinchu, Miaoli and Taichung heavily.
- Heavy rainfall is scheduled for the elevated areas of the capital Taipei, Nantou, Chiayi and Yilan.
- Coastal cities such as Keelung, Kaohsiung and Pingtung will face severe storms accompanied by strong sea waves.
- Southern Taichung, Matsu, Hualien and the Taitung Mountains remain under warning for sudden heavy rain showers.
Continuous monitoring of the phenomenon’s trajectory is vital, as small changes in the path of the typhoon’s core can transfer the load of destruction to neighboring areas that were not in the main focus. Weather radars operate at maximum capacity to provide real-time updates, feeding mobile phone alert systems that warn the population of immediate dangers and evacuation orders.

Security protocols require immediate preparation of the population
Civil defense advises that domestic preparations be completed before the first severe signs of the storm reach the coast. Civil collaboration dramatically reduces the number of emergency calls, allowing firefighters and paramedics to focus on large-scale incidents such as collapses and flood rescues. The main recommendation is that people remain indoors and safe during the peak of the event, avoiding any type of unnecessary travel.
Practical measures include reinforcing doors and windows, as well as removing any loose objects on balconies and yards that could become a wind-driven projectile. Prior cleaning of gutters and drains is also essential to avoid the accumulation of water on roofs, which could cause infiltrations or roof collapses. At the same time, families must assemble survival kits containing drinking water, non-perishable food, flashlights, extra batteries, a battery-powered radio and continuous-use medicines.
Interruptions in electricity supply and telecommunications networks are treated as certain by infrastructure companies, given the projected strength of the winds. Keeping mobile devices fully charged and establishing a communication plan in advance with relatives helps avoid misunderstandings if services fail. Following official broadcasts ensures access to verified information, combating the spread of rumors and panic during the climate crisis period.
