強い冬型気圧配置　木曜日にかけ大雪の恐れ

-

サハリン付近にある発達した低気圧の動きがこのあと遅くなり、ほとんど停滞する見込みです。このため１８日木曜日にかけて日本付近は強い冬型の気圧配置になり、北日本から西日本では大雪になるところがあります。風も非常に強く、暴風雪に厳重な警戒が必要です。

すでにこの時間は、北日本や東日本の日本海側で、山沿いを中心に断続的に強い雪が降っています。気象庁発表の予想降雪量は、

２４時間降雪量（１７日水曜日１８時までの多い所）
北陸地方７０センチ
東北地方６０センチ
北海道地方、東海地方５０センチ
関東甲信地方、近畿地方、中国地方４０センチ
四国地方、九州北部地方２０センチ

さらにその後の２４時間降雪量（１８日木曜日１８時までの多い所）
北陸地方、近畿地方６０から８０センチ
東北地方、関東甲信地方、東海地方、中国地方４０から６０センチ
北海道地方、四国地方２０から４０センチ
九州北部地方１０から２０センチ

などとなっていて、大雪による交通障害に警戒し、なだれや着雪に注意が必要です。

Hurricane Dora Advisory Number 22 NWS National Hurricane Center Miami FL EP052023 1100 AM HST Sat Aug 05 2023  At 1100 AM HST (2100 UTC), the center of Hurricane Dora was located near latitude 13.3 North, longitude 134.8 West. Dora is moving toward the west near 18 mph (30 km/h), and this motion is expected to continue with some increase in forward speed during the next few days.  Maximum sustained winds have increased to near 130 mph (215 km/h) with higher gusts. Dora is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some additional strengthening is possible this afternoon and tonight. Dora is then expected to weaken beginning Sunday and continuing through Monday.  Dora remains a small hurricane.

As of 9:00 AM on Friday the 11th, Typhoon LAN, an extremely strong typhoon, is slowly moving northward over the sea approximately 90 kilometers southeast of Chichi-jima Island. The central pressure is 940 hectopascals, the maximum sustained wind speed near the center is 45 meters per second, and the maximum gust speed is 65 meters per second. Within a radius of 130 kilometers from the center, there is an area of storm-force winds with speeds exceeding 25 meters per second. The typhoon is expected to continue moving northward while intensifying. There is a possibility that by next Tuesday the 15th, it could directly hit the Tokai region with strong force. As of now, the forecast cone indicating the area where the center of the typhoon has a 70% probability of entering is relatively wide, as the typhoon's future track has not been precisely determined. Therefore, it is important to be aware that it could come quite close not only to the Tokai region but also to the Shikoku and Kinki ...

来週、台風３号が沖縄接近か？

  ４月にフィリピン近海で台風２号が発生して以降、新たな台風が発生しない状況が続いていますが、最新のアメリカ環境予測センター（NCEP）の全球数値予報（GFS）の計算では、来週後半に台風が発生する可能性が出てきました。予想では、６月２９日水曜日にフィリピンの東で熱帯低気圧が発生し、７月１日金曜日に沖縄付近を通過。その後、上海方面に進む見通しです。熱帯低気圧は発達次第で台風３号になるかもしれません。 ただ、ヨーロッパ中期予報センター（ECMWF）の計算では、熱帯低気圧にならないほどの低圧部の予想となっていて、熱帯低気圧が発生するかどうかはまだはっきりと言えない状況です。 Since typhoon No. 2 occurred in the sea near the Philippines in April, no new typhoon has continued, but the latest Global Forecast Prediction (GFS) calculations of National Centers for Environmental Prediction (NCEP) show a possibility that a new typhoon will occur in the second half of next week. It is expected that a tropical cyclone will occur in the east of the Philippines on Wednesday, June 29, and will pass near Okinawa on Friday, July 1. After that, it is expected to proceed toward Shanghai. Tropical cyclones may become typhoon No. 3 depending on their development. However, according to the calculation by the European Center for Medium-Range Predictors (ECMWF), it is predicted that the low p...
