Tomorrow, Monday the 19th, a low-pressure system accompanied by a front will move eastward across the northern Sea of ??Japan, causing deteriorating weather?primarily along the Sea of ??Japan coast from Western to Northern Japan. In the Kanto region, although the area remains under the influence of a high-pressure system, the influx of moist air is expected to lead to increased cloud cover.
Additionally, the pressure gradient around the low-pressure system will tighten, with strong winds forecast for Eastern and Northern Japan.



Weather in Northern Japan
In Northern Japan, a low-pressure system with an associated front will pass near Sakhalin, causing rain and wind to intensify in Hokkaido from the afternoon onwards. Please exercise caution, as heavy rain is possible in the southern part of Hokkaido.
In the Tohoku region, rain will also intensify between the afternoon and evening; some areas along the Sea of ??Japan coast may experience heavy thunderstorms, so please be careful. Remember to bring rain gear when heading out to work or school.

Weather in Eastern Japan
Although Eastern Japan will be under the influence of a migratory high-pressure system located to the east of Japan, the influx of moist air will likely result in increased cloud cover, with rain expected by late at night.
Along the Pacific coast of the Kanto region, the pressure gradient will tighten, leading to stronger winds in areas such as Tokyo and Yokohama.

Weather in Western Japan
In Western Japan, a cold front is expected to move eastward from the Sea of ??Japan, causing weather conditions to deteriorate?particularly along the Sea of ??Japan coast. Across a wide area?including the Kyushu, Chugoku, and Kinki regions?rain is expected to intensify from the early morning hours through late at night. Atmospheric conditions will become highly unstable, and some parts of the Chugoku region may experience localized, intense thunderstorms.

As of 9:00 a.m. today, Sunday the 18th, the very strong Typhoon No. 30 (Champi) is located over the Mariana Islands and is moving westward at a speed of 25 km/h. The central pressure is 945 hPa, with maximum sustained winds of 50 m/s near the center and peak gusts of 70 m/s.

-------------------------------
Typhoon No. 30 ? Sunday, the 18th, 9:00 AM
Location: Mariana Islands
Size Category: N/A
Intensity: Very Strong
Movement: West, 25 km/h
Central Pressure: 945 hPa
Max. Sustained Wind: 50 m/s (near the center)
Max. Gust Speed: 70 m/s
--------------------------------






The typhoon is expected to continue intensifying as it moves westward, reaching a "violent" (top-tier) intensity between tonight and the morning of Monday, the 19th. By around the 23rd?later in the week?it is projected to reach the waters south of Okinawa while maintaining a "very strong" intensity. In Okinawa, even while the storm's center remains at a distance, the region is expected to begin experiencing the effects of strong winds and high waves driven by the typhoon's swell, starting from the middle of the week. Regarding the subsequent path of the typhoon, current forecasts now suggest that a high-pressure system will strengthen, making a westward track increasingly likely. However, because the behavior of this high-pressure system is linked to the intensity of the typhoon itself, there remains a high degree of uncertainty.

There is also a possibility that the typhoon could move northward through the East China Sea and approach western Japan; therefore, please be sure to check the latest typhoon information regularly.

[Typhoon Information] Typhoon No. 30 is expected to approach the Sakishima Islands around the 23rd, while maintaining its status as a very strong typhoon.
