Risk of rain-triggered disaster may increase in Shikoku in western Japan
The Meteorological Agency says an inflow of warm, moist air around a high-pressure system has been making atmospheric conditions very unstable mainly on the Pacific side of eastern and western Japan.
Changeable weather is expected to continue through late Thursday afternoon in eastern Japan and through Friday in western Japan, mainly on the Pacific side, with chances of heavy rain and localized thunderstorms.
Bands of heavy rainclouds could develop over Kochi and Tokushima prefectures in Shikoku through late Thursday evening.
Rainfall over the 24-hour period through Friday morning is expected to total 250 millimeters in Shikoku, 200 millimeters in Tokai, 180 millimeters in Kinki and 100 millimeters in Kanto-Koshin.
In addition to rain-triggered disasters, weather officials are urging caution for lightning strikes, gusty winds and hail.
Meanwhile, the extending high-pressure system will push temperatures up on Thursday, mainly on the Sea of Japan side of western Japan.
Heatstroke alerts have been issued for eight prefectures in western Japan.
People are advised to use air conditioners, take in plenty of water and salt and rest regularly if working outdoors.

44 dead, 9 missing due to heavy rain in Beijing suburbs
Local authorities in Beijing said on Thursday that 44 people have died and nine others are missing due to recent heavy rain. The precipitation, which continued for a week through Tuesday, caused flooding and mudslides in mountainous areas of the Chinese capital. Many of the dead were from a facility for elderly people in the Miyun district. The district's chief acknowledged its response was insufficient, saying the facility was not included within a zone where people should evacuate under an emergency plan. Many posts have been seen on Chinese social media saying that senior Beijing city officials should resign to take responsibility for the outcome. In the summer of 2023, flooding and mudslides caused by heavy rain also resulted in severe damage in suburbs of the Chinese capital. Authorities said at that time that 33 people died and 18 others were missing.

Japan's agriculture ministry to help farmers cope with extreme heat
Japan's agriculture ministry has set up a taskforce to address growing concern that this summer's high temperatures and lack of rain could affect rice and other crops in some parts of the country. At the first meeting of the taskforce on Thursday, Agriculture Minister Koizumi Shinjiro instructed officials to encourage farmers to conserve water and to let them know about a subsidy program for water pumps. The officials were also asked to try to persuade farmers to switch to heat-resistant varieties. The ministry says rice farmers in some parts of the Tohoku and Hokuriku regions have reported poor crop growth. It adds that the extreme heat has so far only had a limited impact on farming in the rest of the country.
