The rainy season front in Japan is currently stagnant in the south, with clouds spreading from east to west near Honshu. This weather pattern is bringing rain and thunderstorms to the region, according to weather forecaster Keiko Shiraishi from the Japan Weather Association.
On June 23, 2023, the clouds were observed spreading across the southern part of Japan and around Honshu. The sky is not expected to be clear, and there will be areas experiencing rain and thunderstorms.
The area around Honshu, which is on the north side of the seasonal rain front, is particularly prone to rain, thunderstorms, and even heavy rain. The atmospheric conditions in the Tohoku, Hokuriku, and Kanto regions are unstable, making it likely for rain clouds to develop. Hokkaido to the Chugoku region will also experience rainfall, while the Tohoku region can expect heavy rain accompanied by thunder. Kanto and Hokuriku may also experience thunderstorms.
In Okinawa, where the seasonal rain front hits, heavy rain is expected due to rain and thunderstorms, mainly in the main island region. The Amami region, which was recently hit by heavy rain, will also experience rain clouds and thunderclouds. The ground in these areas has already loosened due to the heavy rain, making them susceptible to landslides even with a small amount of rain. Residents are advised to exercise caution.
Shiraishi also provided tips on how to identify approaching thunderclouds and what to do in such situations. Signs of an approaching thundercloud include a black cloud approaching, rumbling thunder, and a sudden cold wind. If any of these changes are observed, it is recommended to evacuate to a safe place immediately, as heavy rain and thunder may occur soon.
The best places to seek shelter during a thunderstorm are nearby solid buildings or inside a car. Taking shelter under a tree is dangerous as lightning can jump from the tree to people. If there is no available shelter, individuals should squat down with their feet together, head down, and cover their ears with both hands.
It is important to note that intense phenomena caused by isolated thunderclouds often subside within 30 minutes to an hour. While waiting for the thundercloud to pass, individuals should stay updated with the latest information, such as checking the rain cloud radar on their smartphones, and remain in a safe place.
As the rainy season front remains stagnant in the south of Japan, residents are advised to stay informed about the weather conditions and take necessary precautions to ensure their safety.
How is the instability of ions contributing to the spread and intensification of clouds?
Ions are unstable, causing the clouds to spread and intensify.
According to meteorologist Keiko Shiraishi, this stagnant weather pattern is expected to continue for the next few days. The rainy season front is not moving northward as it usually does during this time of year. Instead, it is lingering around Honshu, resulting in widespread clouds and rain across the region.
Residents in the affected areas are advised to take necessary precautions and stay updated with the latest weather information. Heavy rain can lead to localized flooding and potential landslides, so it is important to be aware of any evacuation orders or advisories issued by local authorities.
The stagnant rainy season front is also causing cooler temperatures compared to normal for this time of year. People are advised to dress accordingly and take measures to stay warm and dry.
As for the rest of Japan, the weather is expected to remain relatively dry and sunny. The rainy season front is not affecting areas further north, such as Hokkaido and Tohoku. Therefore, these regions can expect clear skies and warm temperatures.
It is uncertain when the rainy season front will start progressing northward. Weather forecasters are closely monitoring the situation and will provide updates as necessary.
In the meantime, residents in the affected areas should be prepared for continued rain and thunderstorms. Stay indoors during storms and avoid traveling unless absolutely necessary. Keep an eye on the latest weather bulletins and follow any safety instructions given by local authorities.
Overall, the stagnant rainy season front in southern Japan is causing widespread rain and thunderstorms in the Honshu region. Residents are advised to stay informed and take necessary precautions to ensure their safety during this weather event.
