Arab Weather - The Japanese capital, Tokyo, and other cities have witnessed unusually heavy rains over the past two days, prompting authorities to sound sirens in several areas to warn of the risk of flooding and mudslides.

 

Heavy rains disrupt cities and infrastructure

Japan was affected by a deep depression accompanied by a humid tropical air current, resulting in extremely heavy rainfall in a short period of time. The Japan Meteorological Agency reported that some areas in and around Tokyo recorded rainfall exceeding 100 mm, which is sufficient to cause flash floods.

 

As the weather worsened, local authorities sounded sirens to warn residents of the possibility of flash floods. They urged citizens to take extreme caution and avoid riverbeds and areas of runoff. Warnings were also issued of mudslides in some mountainous areas due to waterlogging, particularly in western Tokyo and parts of Kanagawa Prefecture.

 

Suspension of services and stoppage of transportation

The extreme weather conditions caused delays or temporary suspensions on several metro and high-speed train lines, as well as the cancellation of some domestic flights, while emergency and rescue teams were deployed to vulnerable areas.

 

A new tropical storm is heading towards Japan, and flooding fears are returning.

Meteorologists at the Arab Weather Regional Center said that the latest computer map readings indicate that Japan is on the cusp of a new tropical storm in the coming days. It is expected to be accompanied by strong winds and torrential rains, potentially affecting the capital, Tokyo, directly.

These weather conditions are likely to increase the likelihood of flash floods and torrential rains again, especially in areas still reeling from the effects of the previous storm.

 

In this context, Japan is affected during the summer by a number of changing atmospheric pressure systems, sometimes accompanied by an influx of moisture from the southeast across the Pacific Ocean, leading to severe weather disturbances, especially given the mountainous terrain that enhances the strength of cumulus formations.

 

And God knows best.
