Rainy season arrives early in Japan's southern Kyushu region
Japanese weather officials say the rainy season appears to have begun in the southern Kyushu region. The Japan Meteorological Agency made the announcement on Friday. The Kyushu and Shikoku regions are experiencing intermittent rains due to moist air flowing toward a weather front around the East China Sea. Southern Kyushu is likely to see clouds and rain for about a week. The start of the season in the region comes 14 days earlier than usual and 23 days earlier than last year. This year, the rains have not yet arrived in the southwestern regions of Okinawa and Amami, where the season usually starts. It could be the first time that southern Kyushu has experienced the rainy season before the southwestern regions of Okinawa and Amami since 1951, when the agency started keeping records. Meanwhile, unstable atmospheric conditions are expected in the country on Saturday due to a weather front and a passing low-pressure area. Western and eastern Japan are expected to get very heavy rains. Weather officials are warning of possible lightning, strong winds and tornadoes.

Torrential rain expected in western to eastern Japan through Saturday
Japanese weather officials are forecasting extremely heavy rain with thunder in western and eastern parts of the country through Saturday due to the effects of a low pressure system and weather front. The meteorological agency says the front brought rainfall to wide areas in western Japan on Friday. The agency says rain clouds have developed over some parts of the Kyushu region. As of 6 p.m. on Friday, extremely heavy rain of 50.5 millimeters per hour fell in Sasebo City, Nagasaki Prefecture, and 32.5 millimeters per hour in Imari City, Saga Prefecture. The low pressure system also brought strong winds to western Japan. In the three-hour period through 6 p.m., a maximum instantaneous wind speed of about 96 kilometers per hour was recorded in Higashikagawa City, Kagawa Prefecture. Localized downpours of more than 50 millimeters per hour with thunder will likely hit western Japan through Saturday morning, and some parts of eastern Japan on the Pacific coast side through Saturday afternoon as the front moves eastward. Weather officials say warning-level torrential rain may fall if rain clouds develop more than expected or they remain stationary. They are calling on people to be on a heightened alert for mudslides, flooding in low-lying areas and swollen rivers. Caution is also advised against lightning strikes, gusts, and strong winds such as tornadoes.
