Overview
- The Japan Meteorological Agency issued early weather information for Kyushu, including Yamaguchi, flagging a high chance of "considerably low" temperatures beginning around Jan. 21.
- The Okinawa Meteorological Observatory released the same alert for the island region, indicating conditions that meet once-in-a-decade thresholds in the JMA outlook.
- Forecast guidance projects minimum temperatures near 13°C in Naha and 12°C in South Daito, with colder, windier conditions and higher waves expected to persist into early February.
- Authorities advise protecting vulnerable crops and preventing water pipe freezing, and they urge residents and operators to monitor updates for timing and intensity changes.
- An unusual pattern combines a strong southward cold surge with January’s Typhoon No. 1 east of Mindanao, which is expected to weaken before reaching Okinawa but may keep seas rough.
