Rapidly developing low-pressure system Hokkaido has the lowest pressure in history in a high-tide storm
With the approach of a rapidly developing cyclone, the atmospheric pressure in Hokkaido has dropped to a record level. Furthermore, the tide level rises at its peak at dawn and storms blow mainly in coastal areas.
Hokkaido Atmospheric pressure drops Some places have updated the number one value since the beginning of the observation
From yesterday 15 to today 16, a low pressure system advanced from the vicinity of Honshu to Hokkaido.
The central pressure of the cyclone is 998 hPa at 3:00 am on the 15th and 948 hPa at 3:00 am on the 16th. It was drastically reduced by 50 hPa in 24 hours.
With the approach of this low-pressure system, atmospheric pressure drops sharply in Hokkaido. The lower pressures on sea level in each region (* preliminary figures as of 6:00 am on the 16th) have updated the number one value in the long history of observation for more than 100 years.
● Nemuro: 947.8 hPa (4:32 a. M.)
The lowest since the observation began in 1879 was 948.7 hPa on February 22, 1994.
● Kushiro: 956.4 hPa (3:30 a. M.)
The lowest since the observation began in 1910 was 957.4 hPa on February 22, 1994.
● Abashiri: 956.7 hPa (5:34 a. M.)
The lowest since the beginning of the observation in 1890 was 957.6 hPa on May 10, 1954.
The tide level also rises and the storm blows
As low pressure approaches, the tide level rises at the peak of sunrise on the east coast of Hokkaido. Some lowlands near the coast have been flooded.
In addition, the maximum instantaneous wind speed (2 am) of 35.5 m / s was observed in Nemuro City, and very strong winds like when a typhoon was approaching mainly in the eastern part, and the winds gradually in the southwestern and northern part. It is getting stronger. From now on, it looks like there will be places where going out will be dangerous due to a storm and blizzard.
