Typhoon Noru Slams Japan

Posted by on Saturday, August 5, 2017

Typhoon Noru is currently a strong tropical cyclone approaching the Japanese island of Kyushu.

It is one of the longest-lasting tropical cyclones of the Northwest Pacific Ocean on record, and the most intense tropical cyclone of this basin in 2017.

Although the JMA downgraded Noru to a severe tropical storm at around on July 29, it had reformed an eye while situated 70 km to the east of Chichijima, the largest Ogasawara island.

Early on July 30, Noru began to improve its convective structure, making both of the JMA and the JTWC upgrade Noru to a typhoon again.

Over the following 24 hours, Noru explosively intensified, and the JTWC reported that it had become a Category 5 super typhoon about 225 km south of Iwo To at around 18:00 UTC.

The typhoon took on annular characteristics, with a symmetric ring of deep convection surrounding a 30 km well-defined eye and fairly uniform cloud top temperatures. 

Typhoon Noru has brought more than 500 mm of rain & will continue to bring heavy rain, gusty winds to parts of Japan.
