From around the 21st (Tuesday) until the 22nd (wo), because of the typhoon no. 19 there is a possibility that the weather will be very rough around West-Japan.

"Brother" strong typhoon 19 continues to develop, in the direction of Kyushu To
strong typhoon 19 with a storm zone, may be quite close to the southern part of Kyushu and the Amami area around 21 (Tuesday) There are is. Typhoon 19 is already a strong force, but the temperature of the sea surface in the sea area around the typhoon is high and the expectation is that it will develop further. It will become a "very strong" force in the future and it can approach the southern part of Kyushu and the Amami region. In these areas the violent wind that blows the carriage can fall, and on the sea it can be a violent muzzle. Along with high waves accompanied by storms and undulation, vigilance is required for sediment-related disasters caused by heavy rainfall, flooding of lowlands, flooding of rivers and flooding. Even when wind and waves increase in Shikoku, we need vigilance.
"Brother" What is the trend of Typhoon No. 20
Typhoon 20 that took place late Saturday, September 18, late in the evening, is expected to gradually come to Japan in the future. According to the latest forecast, we will reverse the Pacific High Pressure line, and it is expected that around Friday Western Japan will approach significantly from Western Japan around Friday 24th. Since the prediction yen are quite large at this stage, there is a wide range of course prediction, so we should pay attention to future typhoon information. On the other hand, high waves accompanied by wave can be mentioned as a point to note from now on. Along with the high waves derived from typhoon 19, attention is needed for relaxation in the sea.
Special attention for the season of the seas! What is the high waves accompanied by "swells"?
"Waves" that the typhoon often hears when approaching. When the wind blows on the sea, a wave is pushed by the wind. However, waves remain, not only when the wind blows, but also after the wind stops, and waves traveling to the area where the wind is not blowing, which is called "wave". This "wave" is characterized by (1) the wave cycle and wave height are large, (2) it is emitted at a distance of several thousand kilometers, and (3) when approaching near the shallow water coast, the wave becomes high. This causes, at first sight, a sudden high wave near the coast, where accidents are more often hit by waves. Even if you are away from typhoons, caution is advised, even if it is sunny when the word "swell" comes out.
