status, but that does not mean the meteorological threat has ended.<\/p>\n<p>The tropical depression is moving north near western Japan while sending a deep plume of warm, moisture-rich air toward the autumn rain front stalled along the Pacific side of Honshu.<\/p>\n<p>That moisture supply is helping thunderstorms repeatedly develop along the front.<\/p>\n<p>The tropical depression is expected to become absorbed into a frontal low around September 9, while the autumn rain front remains active through approximately September 10.<\/p>\n<div class=\"model-block\">\n<strong>Why a weaker tropical system can still cause extreme rain:<\/strong><\/p>\n<p>A tropical cyclone can lose its closed typhoon circulation while still carrying enormous amounts of tropical moisture.<\/p>\n<p>When that moisture collides with a stationary front, rainfall can become more widespread than when the storm had a compact typhoon core.<\/p>\n<\/div>\n<h2>Tokai emergency: linear precipitation band forms in Aichi and Gifu<\/h2>\n<p>This is the most important live update.<\/p>\n<p>JMA reported a <strong>linear precipitation band over western Aichi and the Mino area of Gifu<\/strong> during the afternoon of September 8.<\/p>\n<p>Repeated thunderstorms were moving over the same corridor, rapidly increasing the risk of landslides, river flooding and urban inundation.<\/p>\n<p>At <strong>Komaki, Aichi<\/strong>, 102 mm of rain was measured in only one hour.<\/p>\n<p>Near <strong>Tajimi, Gifu<\/strong>, radar estimates indicated roughly 100 mm in one hour.<\/p>\n<p>Parts of the Aichi\u2013Gifu corridor may have received nearly <strong>150 mm in three hours<\/strong>.<\/p>\n<div class=\"live-block\">\n<h3>Nagoya: Level 4 danger<\/h3>\n<p>Developed thunderstorms moved directly across the Nagoya area during the afternoon.<\/p>\n<p>Heavy Rain Warnings are in effect for both <strong>ground-loosening \/ landslide risk<\/strong> and <strong>inundation risk<\/strong>.<\/p>\n<p>A Flood Warning and Thunderstorm Advisory have also been issued.<\/p>\n<p>People near slopes, rivers and low-lying roads should follow local evacuation information and JMA warning maps rather than waiting for water to enter buildings.<\/p>\n<\/div>\n<h2>Japan rainfall forecast: where JMA sees the largest totals<\/h2>\n<p>Regional JMA guidance for the period into the morning of September 9 has highlighted very large potential totals.<\/p>\n<div class=\"table-wrap\">\n<table class=\"responsive-table\">\n<thead>\n<tr>\n<th>Region<\/th>\n<th>Potential 24-hour rainfall<\/th>\n<th>Main risk<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Kanto-Koshin<\/strong><\/td>\n<td><strong>Up to 250 mm<\/strong><\/td>\n<td>Flash flooding, rivers, landslides; renewed rain

thunderstorms<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>These are <strong>regional maximum forecasts<\/strong>, not city-wide guaranteed totals.<\/p>\n<p>Inside a linear precipitation band, an individual town can receive far more rain than a nearby city only 20\u201330 km away.<\/p>\n<h2>Kanto rain may intensify again tonight<\/h2>\n<p>Kanto had a relative lull during the daytime on September 8, but that improvement may be temporary.<\/p>\n<p>Rain associated with the active Tokai system is expected to spread eastward.<\/p>\n<p>JMA has issued advance information about the possibility of another <strong>linear precipitation band in Kanto-Koshin through early September 9<\/strong>.<\/p>\n<p>Individual thunderstorms may be capable of more than <strong>50 mm in one hour<\/strong>.<\/p>\n<p>This matters especially because parts of Kanto are already saturated from the previous round of exceptional rain.<\/p>\n<h2>Izu Islands and southern Chiba remain extremely vulnerable<\/h2>\n<p>Even if the next rain band does not produce the highest totals there, the ground is already saturated.<\/p>\n<p>By midnight at the start of September 8, observed 24-hour rainfall had reached approximately:<\/p>\n<ul>\n<li><strong>Niijima:<\/strong> 328.0 mm;<\/li>\n<li><strong>Oshima:<\/strong> 310.5 mm;<\/li>\n<li><strong>Katsuura, Chiba:<\/strong> 266.0 mm;<\/li>\n<li><strong>Tateyama, Chiba:<\/strong> 241.0 mm.<\/li>\n<\/ul>\n<p>That means a smaller additional rainfall event can now trigger a much larger hydrological response.<\/p>\n<h2>Why linear precipitation bands are so dangerous<\/h2>\n<p><strong>\u7dda\u72b6\u964d\u6c34\u5e2f<\/strong> is not simply another name for heavy rain.<\/p>\n<p>It describes a narrow corridor where thunderstorms repeatedly develop and move across the same area.<\/p>\n<p>One storm may last only 20\u201330 minutes.<\/p>\n<p>But if five or six storms follow the same track, rainfall can accumulate catastrophically within only a few hours.<\/p>\n<p>This is how locations can move from normal rainfall to:<\/p>\n<ul>\n<li>100 mm in one hour;<\/li>\n<li>150 mm in three hours;<\/li>\n<li>rapid river flooding;<\/li>\n<li>landslides with little warning;<\/li>\n<li>roads becoming impassable.<\/li>\n<\/ul>\n<h2>Severe thunderstorms: lightning, hail and violent gusts<\/h2>\n<p>The danger is not limited to rainfall.<\/p>\n<p>The atmosphere near the front is extremely humid and unstable.<\/p>\n<p>JMA warns about:<\/p>\n<ul>\n<li>frequent lightning;<\/li>\n<li>hail;<\/li>\n<li>severe wind gusts;<\/li>\n<li>rapidly developing thunderstorms;<\/li>\n<li>locally violent gusts associated with tornado-like rotation.<\/li>\n<\/ul>\n<p>If a developed cumulonimbus cloud approaches and conditions suddenly become dark and windy, move inside a sturdy building.<\/p>\n<p>Do not shelter beneath isolated trees.<\/p>\n<h2>Weather Forecaster: the strongest city signals through September 12<\/h2>\n<p>The latest Weather Forecaster forecast model also shows a broad multi-day heavy-rain pattern rather than one isolated wet day.<\/p>\n<div class=\"table-wrap\">\n<table

individual cities.<\/p>\n<p>Official JMA warnings must take priority during linear rain-band events because real thunderstorms can concentrate 50\u2013100+ mm of rain inside a very narrow corridor that a city-grid forecast cannot resolve precisely.<\/p>\n<\/div>\n<h2>Shizuoka: strongest Weather Forecaster accumulation<\/h2>\n<p>Shizuoka remains one of the most concerning locations in the model.<\/p>\n<p>Weather Forecaster currently gives:<\/p>\n<ul>\n<li><strong>September 8:<\/strong> about 124 mm;<\/li>\n<li><strong>September 9:<\/strong> about 91 mm;<\/li>\n<li><strong>September 10:<\/strong> about 23 mm;<\/li>\n<li><strong>September 11:<\/strong> around 53 mm;<\/li>\n<li><strong>September 12:<\/strong> around 20 mm.<\/li>\n<\/ul>\n<p>That is more than <strong>300 mm over five days<\/strong> in the current city-grid forecast.<\/p>\n<p>For Shizuoka, repeated rainfall is particularly dangerous because of steep terrain and the high landslide sensitivity of mountain slopes.<\/p>\n<h2>Nagoya: heavy rain continues after today\u2019s emergency<\/h2>\n<p>Today\u2019s extreme rain does not necessarily end when the current linear rain band weakens.<\/p>\n<p>Weather Forecaster still gives Nagoya approximately:<\/p>\n<ul>\n<li>36 mm September 8;<\/li>\n<li><strong>73 mm September 9;<\/strong><\/li>\n<li>33 mm September 10;<\/li>\n<li><strong>46 mm September 11;<\/strong><\/li>\n<li>37 mm September 12.<\/li>\n<\/ul>\n<p>The model also gives gusts near <strong>53 km\/h on September 9<\/strong>.<\/p>\n<p>After more than 100 mm per hour has already occurred locally in Aichi, any additional rain becomes more dangerous because drainage systems, rivers and slopes are already stressed.<\/p>\n<h2>Tokyo: renewed rain rather than an \u201call clear\u201d<\/h2>\n<p>The Tokyo story has also changed again.<\/p>\n<p>Central Tokyo is not currently showing another 300 mm model day.<\/p>\n<p>Instead, Weather Forecaster now shows a prolonged wet period:<\/p>\n<ul>\n<li><strong>September 8:<\/strong> about 44 mm;<\/li>\n<li><strong>September 9:<\/strong> about 34 mm;<\/li>\n<li>September 10: around 14 mm;<\/li>\n<li><strong>September 11:<\/strong> around 30 mm.<\/li>\n<\/ul>\n<p>Peak model gusts on September 9 reach roughly <strong>53 km\/h<\/strong>.<\/p>\n<p>This is a lower daily total than earlier extreme model runs, but it is still important because Kanto soils and rivers have already been affected by several days of heavy rainfall.<\/p>\n<h2>Yokohama and Chiba<\/h2>\n<p>Yokohama\u2019s current model peak comes on September 9 with around <strong>49 mm<\/strong>.<\/p>\n<p>Chiba has around <strong>29 mm<\/strong> on September 9.<\/p>\n<p>But Chiba\u2019s model number should not be interpreted as low risk.<\/p>\n<p>Southern Chiba has already experienced 24-hour observed rainfall exceeding 240\u2013260 mm in some locations, so landslide and river risk can remain high even when the next forecast total is smaller.<\/p>\n<p>For local conditions, check:<\/p>\n<p>\n<a href=\"https:\/\/pogodnik.com\/en\/10579-weather-in-tokyo-japan\/month\">Tokyo weather<\/a>,<br \/>\n<a

and increase landslide risk in surrounding terrain.<\/p>\n<p>Model gusts may reach around <strong>64 km\/h September 9<\/strong>.<\/p>\n<h2>Hokuriku: Kanazawa rainfall increases sharply<\/h2>\n<p>Kanazawa is another standout.<\/p>\n<p>Weather Forecaster gives approximately <strong>81 mm on September 9<\/strong>, followed by another <strong>41 mm September 11<\/strong>.<\/p>\n<p>The five-day model total is around <strong>175 mm<\/strong>.<\/p>\n<p>This supports the broader official concern for Hokuriku as moist air spreads north and west of the main Pacific-side rain corridor.<\/p>\n<h2>Tohoku: heavy rain shifts north<\/h2>\n<p>Southern Tohoku remains involved in the event.<\/p>\n<p>Sendai currently has around:<\/p>\n<ul>\n<li>14 mm September 8;<\/li>\n<li><strong>40 mm September 9;<\/strong><\/li>\n<li>19 mm September 11.<\/li>\n<\/ul>\n<p>The risk is smaller than Tokai in the current city model, but the front is broad enough for local heavy thunderstorms to produce much higher amounts.<\/p>\n<h2>Transport: expect disruption to change rapidly<\/h2>\n<p>The previous version of this article listed specific JR East cancellations from September 7.<\/p>\n<p>Those details are now too time-sensitive to keep as a static list.<\/p>\n<p>Heavy rain can trigger:<\/p>\n<ul>\n<li>temporary line suspensions;<\/li>\n<li>speed restrictions;<\/li>\n<li>planned service reductions;<\/li>\n<li>highway closures;<\/li>\n<li>flight delays;<\/li>\n<li>local evacuation-related road restrictions.<\/li>\n<\/ul>\n<div class=\"travel-block\">\n<strong>Before traveling:<\/strong><\/p>\n<p>Check JMA warnings, local evacuation information and the live status page for the railway operator serving your route.<\/p>\n<p>Do not assume a train that operated normally in the morning will continue operating through an afternoon linear rain band.<\/p>\n<\/div>\n<h2>What happens September 9\u201310?<\/h2>\n<p>The threat does not end tonight.<\/p>\n<p>The tropical depression is expected to become part of a low-pressure system along the autumn front.<\/p>\n<p>The front itself remains near Japan.<\/p>\n<p>That means the moisture source changes shape, but the rainfall mechanism remains active.<\/p>\n<h3>September 9<\/h3>\n<p>The main concern shifts between Tokai, Kanto-Koshin, Hokuriku and neighboring regions.<\/p>\n<p>Tokyo and Yokohama may see renewed heavy rain.<\/p>\n<p>Kanazawa and Nagoya remain particularly wet in the Weather Forecaster forecast.<\/p>\n<h3>September 10<\/h3>\n<p>Rain continues in many areas rather than clearing Japan completely.<\/p>\n<p>Weather Forecaster remains especially wet around Shizuoka, Nagoya, Osaka and Kochi.<\/p>\n<p>Even where rainfall temporarily eases, landslide danger can remain elevated because slopes respond to accumulated multi-day rainfall.<\/p>\n<h2>What people should do<\/h2>\n<ul>\n<li><strong>Do not wait for visible flooding.<\/strong> Follow Level 4 evacuation information before escape routes become blocked.<\/li>\n<li><strong>Avoid rivers and drainage channels.<\/strong> Water levels can rise extremely quickly upstream.<\/li>\n<li><strong>Stay away from steep slopes.<\/strong> Landslides can occur after the heaviest rain has already passed.<\/li>\n<li><strong>Never drive through floodwater.<\/strong> Depth and road damage are often impossible to judge.<\/li>\n<li><strong>During thunderstorms:<\/strong> move inside a sturdy building because lightning, hail and violent gusts are possible.<\/li>\n<li><strong>Check radar frequently.<\/strong> Linear rain bands can form and shift over a relatively small area.<\/li>\n<\/ul>\n<h2>What search users need now<\/h2>\n<p>The best
