Meteorological history

Early on 20 October, the Japan Meteorological Agency (JMA) upgraded an area of low pressure into a tropical depression.[2] Later that day, the JMA reported that the tropical depression slightly intensified.[3] The next day, the Joint Typhoon Warning Center started monitoring the system as tropical depression 16W.[4] On 23 October, the system entered the Philippine Area of responsibility and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) started monitoring the system as Tropical Depression "Katring"[5] On 24 October, the JMA and JTWC upgraded the tropical depression into a tropical storm and the JMA named it "Chaba".[6][7] On 25 October, the JMA further upgraded the storm into a Severe Tropical Storm.[8] Later that day, the JTWC upgraded the storm into a Category 1 Typhoon.[9] Early on 26 October, the JMA further upgraded the storm into a Typhoon.[10] Early on 27 October, the JTWC upgraded the typhoon into a Category 2 Typhoon.[11] Later that day, the JTWC further upgraded the typhoon into a Category 3 Typhoon.[12] The following day JTWC upgraded the system into a Category 4 Typhon.[13] Later that day, the JTWC downgraded Chaba into a Category 3 Typhoon.[14] Early on 29 October, the JTWC further downgraded Chaba into a Category 2 Typhoon, while the JTWC downgraded it into a Category 1 Typhoon.[15] Early on 30 October, the JTWC reported that Chaba had transitioned into an extratropical cyclone. During the afternoon of 30 October, the JMA downgraded Chaba to a remnant low as passed near Japan. The remnants of Chaba continued to weaken as it moved northeast, but strengthened again in approaching the Gulf of Alaska into a major storm[16] with 55-knot winds,[17] kicking up 40–50 foot waves, with pressure as low as 939 mb.[18] The storm's center came ashore in the vicinity of Cordova, Alaska on 1 November, but not before pulling an atmospheric river of moisture into the American Pacific Northwest, setting a record[19] for that date of precipitation in Seattle.

Preparations and impact

Chaba approaching southern Japan on October 29

In preparation for Chaba, more than 160 flights were cancelled.[20] Islanders in southern Japan started sandbagging doors and reinforcing windows as Chaba churned closer.[21] Strong winds and heavy rains lashed through Okinawa and there were a lot of concerns about the island of Amami which was in the typhoon's path.[22] Over 257 residents were evacuated from the Amami Islands to higher grounds, schools and town halls which were converted into evacuation centers.[1] Late on 29 October, Chaba approached Amami island region in Kagoshima. Strong winds injured five people and felled electric poles cutting electricity supply.[23] Landfall was predicted on the main island of Honshu.[24]

On Minami-Daito Island in Okinawa Prefecture, winds from the typhoon gusted up to 160 km/h (99 mph), resulting in roughly 500 residences losing power. Five people were also injured across the island.[23] Chaba dumped nearly 50 mm (2.0 in) of rain per hour across southern Japan. The Japan Racing Association postponed races in Tokyo until 1 November because of the typhoon.[25]

Retirement

The name Katring was subsequently retired after the usage of this name and eventually replaced with the name Kanor, later changed to Karding.[26]
