Typhoon No. 14 approaches the Daitojima region on 8

Typhoon No. 14 is almost stagnant in southern Japan at 3:00 p.m. on the 6th. The central pressure is 992 hectopascals and the maximum wind speed near the center is 23 meters.
High pressure is projected from the mainland near Japan, and Typhoon No. 14 is slowing down due to high pressure blocking northward movement. Typhoon No. 14 will move from the west and become a strong force on the 7th, accompanied by a storm area with a wind speed of 25 meters or more. The 8th is expected to approach the Daitojima region with strong force, accompanied by a storm zone. Watch out for storms in the Daitojima region.

Increased activity in front of autumn rains Fear of heavy rain even before typhoon approaches

In the afternoon of the 7th it will gradually start raining from Kanto to Kyushu, and on the 8th the rain clouds are expected to develop mainly. on the Pacific Ocean side.

Typhoon No. May 14 will slow down even as it gets closer to Japan Will the impact last?

In autumn, the westerly wind that causes typhoons will pass near Japan. For this reason, typhoons often turn westward and accelerate as they approach Japan. However, around the 10th, when Typhoon No. 14 is moving north towards the vicinity of Kyushu, the westerly wind will flow to the north of Japan and is expected not to drop in the vicinity of Honshu even in the middle of next week. For this reason, Typhoon No. 14 can move slowly even as it moves north into the vicinity of Kyushu and Honshu.

The course ahead of Typhoon No. 14 and the forecast circle is wide. Even if you go north near Honshu, you still don’t know when or where you will go, but if you move slowly, the effects of wind and rain can continue for several days.

Also, typhoons are generally said to thrive in areas where the sea surface temperature is 26 ° C to 27 ° C or higher. The sea surface temperature in southern Japan is about 27 ° C, and Typhoon No. 14 can progress as it develops by passing through this area.

Even before the typhoon approaches, there are places where heavy rains will occur due to the influence of the front line, and if the influence of the typhoon is prolonged, it is possible that the amount of rain since the beginning of the rain will increase.

In case of flood damage, clean side trenches and drainage ditches to improve drainage, and inspect and reinforce roofs, walls, walls, etc., in preparation for the approach of a typhoon.
