At 3:00 p.m. on October 5 (Monday), Typhoon No. 14 (Chang Hong) is almost stagnant in the sea south of Japan. Starting tomorrow it will slowly move north, and for a time it will strengthen its power to advance in the area of the environment conducive to the development of typhoons, and it is expected to become a strong power on Wednesday 7.
If you follow the road closer to Honshu, heavy rains can occur on the Pacific side of western and eastern Japan, so you need to be careful of future trends.

In the future, it is expected to move north without much development and shift to a tropical low pressure off the coast of Shikoku. Although the effect of a typhoon is small, there is a risk that rain and wind will intensify mainly on the Pacific side from 23-24 by stimulating the front line after switching to tropical low pressure.

(Reference) Forecasts around the world
The typhoon will continue north over the weekend and may approach western Japan later in the week. However, the forecast circle is very large and it is difficult to delineate the course at this stage. (* The size of the forecast circle does not indicate the strength or size of the typhoon, but the uncertainty of the course.)
Comparing future positions with simulation results calculated by meteorological agencies around the world, such as Europe and the United States, it can be said that there is a wide range of possible paths, from those that go west near Okinawa to those that go towards the east south of Honshu. I get it. The course it takes depends on the forces of high pressure, the jet airflow over the sky, and the position of the pressure valley.
Race forecasts get more accurate as the days go by, so be sure to check the latest information from time to time.
Although Typhoon No. 12 is not expected to develop significantly, it may trigger activity from the autumn rain front that is stagnant in southern Honshu, or it may shift to temperate low-pressure nature and approach Honshu.
On the afternoon of the 21 (Monday), the area around the Kii Peninsula is likely to have the most rainfall, with heavy rains of more than 300mm expected in 48 hours through the night of the 24 (Thursday). Even in the Kanto region, the rain will mainly intensify on the Boso Peninsula, which is close to the front line, and heavy rains of 200mm or more are expected in many places.
Future power and heading will change depending on the relationship to the pressure valley in the sky approaching from the west, so check the latest forecast from time to time. Weather News will continue to monitor the impact and keep you informed.
Typhoon number in normal years
Typhoon No. 14 is the first typhoon to occur in October this year. The average number of typhoons in October is 3.6.
This year, the total number of typhoons that occurred in July was very small, at 2, but there were 7 typhoons in August and 4 typhoons in September.
Although the number of typhoons starts to decrease in October of each year, we cannot be vigilant because we can approach the Honshu area with strong force. Recheck preparations for heavy rains and storms caused by typhoons.
As for the names of typhoons, 140 names proposed by the member countries of the international organization “Typhoon Committee” are prepared in advance and given in the order of appearance.
Typhoon # 14’s name “Chan-hom” is a name proposed by Laos and is derived from the name of the tree.
