Typhoon Ambil nears landfall

Over the past 12 hours, a tropical storm has rapidly intensified into a formidable typhoon. With a well-defined eye and strong winds, this storm is expected to cause significant disruptions, especially along Japan’s coastal regions. As it approaches the mainland, it’s crucial to stay informed and prepared for the impacts this typhoon may bring.

The Evolution of the Typhoon

The storm has evolved from a modest tropical system into a powerful typhoon. The Japan Meteorological Agency has been closely monitoring its development, and reports indicate that the storm may even reach borderline super typhoon status, with the potential to become a Category 4 storm. This significant strengthening has raised concerns about the potential impacts, especially for areas along the eastern coast of Japan.

Projected Path and Impact Areas

As the typhoon approaches Japan, it is expected to track close to the eastern coastline, with the worst impacts likely in Kanagawa and Chiba prefectures. Although the storm’s inner core, where the most destructive winds are concentrated, is expected to remain just offshore, the mainland is still at risk of experiencing severe weather conditions.

Kanagawa and Chiba: Preparing for Impact

Residents in Kanagawa and Chiba should prepare for heavy rainfall, strong winds, and dangerous sea conditions. Rainfall totals in some areas could exceed 300 millimeters, particularly along the coastline. These conditions are likely to lead to localized flooding, especially in low-lying areas, and power outages due to downed trees and power lines. Even though the storm’s core may not make direct landfall, the outer bands of the typhoon are expected to bring tropical storm-force winds and torrential rain.

In Tokyo, rainfall is expected to range between 200 and 250 millimeters, accompanied by winds of 80 to 90 kilometers per hour. These conditions are enough to cause significant disruptions, including delays and cancellations of public transportation, school closures, and potential flooding in urban areas. For those in Yokohama, similar conditions are expected, with the added risk of storm surges along the coast.

A Look Back: Comparing to Previous Storms

While this typhoon is expected to bring significant impacts, it’s important to note that it’s not anticipated to be as severe as Typhoon Faxai, which struck Japan about five years ago. Faxai made a direct hit on the Kanto region, causing widespread damage and leaving hundreds of thousands without power for days. This storm, while strong, is likely to stay just offshore, sparing the mainland from the worst of its winds. However, it’s still expected to cause enough disruption to warrant serious preparation.

Timeline: What to Expect and When

Friday Morning:

As the storm approaches, the first impacts will be felt in the early hours of Friday. Rain will begin to intensify along the coast, with wind speeds gradually increasing. By mid-morning, conditions will have deteriorated enough to disrupt daily activities, particularly in coastal regions.

Friday Afternoon:

The storm will be at its closest approach to Japan by Friday afternoon. This is when the strongest winds and heaviest rainfall are expected. Coastal areas in Kanagawa and Chiba will experience the brunt of the storm, with winds possibly reaching 165 to 170 kilometers per hour just offshore. Rainfall rates could exceed 50 millimeters per hour, leading to rapid flooding in susceptible areas.

In Tokyo, conditions will be severe enough to cause significant disruptions, but the worst impacts will likely remain along the coast. Train services may be delayed or canceled, and urban flooding could become an issue, especially in areas with poor drainage systems.

Friday Evening:

By evening, the storm will begin to move away from the mainland, but dangerous conditions will persist into the night. Winds will gradually decrease, but heavy rain will continue, particularly in areas north of the storm’s path. Coastal flooding and high waves will remain a threat along the entire eastern coast of Japan.

Saturday:

As the storm moves further offshore, conditions will begin to improve. By Saturday morning, rain will taper off, and winds will subside significantly. Cleanup efforts can begin, and by Sunday, much of Japan will see a return to calmer, drier weather.

Detailed Forecast for Key Regions

Kanagawa Prefecture

  • Rainfall: 200-300 millimeters
  • Wind Speeds: 120-150 kilometers per hour
  • Key Concerns: Coastal flooding, power outages, train delays, and potential landslides in mountainous areas.

Kanagawa, especially its coastal areas, will be among the hardest hit. With the storm passing just offshore, high winds and heavy rain are expected to cause significant disruptions. Coastal flooding is a major concern, particularly in low-lying areas like Yokosuka. Residents should prepare for power outages and potential transportation disruptions, particularly on Friday afternoon and evening.

Chiba Prefecture

  • Rainfall: 250-350 millimeters
  • Wind Speeds: 130-160 kilometers per hour
  • Key Concerns: Severe coastal flooding, storm surges, significant power outages, and damage to infrastructure.

Chiba will also face severe impacts from the storm, particularly along its eastern coastline. The combination of heavy rain and strong winds is likely to lead to widespread flooding, especially in areas near rivers and streams. The storm surge could also cause significant damage to coastal infrastructure. Residents should take precautions to protect their homes and should be prepared for extended periods without power.

Tokyo Metropolitan Area

  • Rainfall: 200-250 millimeters
  • Wind Speeds: 80-100 kilometers per hour
  • Key Concerns: Urban flooding, transportation delays, and disruptions to daily activities.

In Tokyo, the main concerns will be heavy rainfall and strong winds, which are likely to cause urban flooding and disrupt transportation networks. While the storm is not expected to make a direct hit, the sheer volume of rain and the strength of the winds will still create hazardous conditions, particularly during the Friday afternoon and evening rush hours. Residents should be prepared for delays in public transportation and potential street flooding.

Yokohama

  • Rainfall: 150-250 millimeters
  • Wind Speeds: 90-120 kilometers per hour
  • Key Concerns: Coastal flooding, power outages, and transportation disruptions.

Yokohama, like Tokyo, will experience significant impacts from the storm, though it is expected to be slightly less severe than in Chiba or Kanagawa. Coastal areas are at risk for flooding, particularly if the storm’s winds push water into Tokyo Bay. Public transportation may be delayed or canceled, and residents should prepare for potential power outages.

Preparation Tips: How to Stay Safe

With the typhoon expected to bring severe weather conditions to much of eastern Japan, it’s essential to take steps to prepare. Here are some tips to help you stay safe:

Before the Storm:

  1. Secure Loose Objects: Bring in any outdoor furniture, decorations, or other items that could become projectiles in high winds. If you can’t bring them inside, secure them with ropes or heavy weights.
  2. Check Emergency Supplies: Ensure you have enough food, water, and medications to last at least three days. Power outages are likely, so stock up on batteries, flashlights, and portable chargers.
  3. Review Evacuation Plans: Know your evacuation route and the location of your nearest shelter. If you live in a flood-prone area, consider relocating to higher ground before the storm hits.
  4. Protect Your Home: If possible, install storm shutters or board up windows to protect against flying debris. Move valuable items to higher floors to protect them from potential flooding.

During the Storm:

  1. Stay Indoors: Avoid going outside during the storm, especially when the winds are strongest. Flying debris can cause serious injuries.
  2. Monitor Updates: Keep a battery-powered radio or another device handy to receive weather updates and emergency instructions.
  3. Avoid Flooded Areas: If you must go outside during the storm, avoid walking or driving through flooded areas. Water levels can rise quickly, and even shallow water can be dangerous.

After the Storm:

  1. Assess Damage Safely: Once the storm has passed, check your property for damage, but do so carefully.
