In the wake of damaging impacts from a one-two punch produced by typhoons Haishen and Maysak across the Korean Peninsula and Japan, residents will have to deal with daily rounds of showers and thunderstorms through the weekend while recovery efforts take place.
“An unsettled weather pattern will bring scattered showers and thunderstorms to Japan and the Korean Peninsula over the next couple of days,” AccuWeather Meteorologist Tony Zartman said.
Some of these storms may threaten to cause flash flooding across areas recently affected by Haishen and Maysak, Zartman added.
AccuWeather meteorologists expect the greatest threat to occur from Friday to Sunday across central and southern Japan as a surge of moisture sparks locally drenching showers and thunderstorms.
As of Wednesday afternoon, there remained about 110 homes in Nagasaki and Kagoshima prefectures without power, according to Kyushu Electric Power Co. This is down from a peak of over 100,000 in the wake of Haishen.
By Thursday, power had been restored to all homes in the region.

With recovery efforts still underway, these thunderstorms could slow cleanup projects and delay power restoration in some areas.

“Thunderstorms that develop from late this week into the weekend will be capable of producing 50-100 mm (2-4 inches) of rain within a short period of time,” Zartman said.
He warned that while these are not expected to produce widespread flooding, additional rainfall in areas that recently received heavy rain from Haishen or Maysak could quickly force small streams to rise and cause flooding in low-lying areas.
With soil already saturated in many areas, landslides may also threaten where the heaviest rain falls.
Even in areas that do not get the heaviest rainfall, travel can also be impacted with reduced visibility and thunderstorms causing delays at airports.
As this area of low pressure slowly weakens early next week, the threat of heavy thunderstorms is expected to wane; however, the region may continue to get isolated thunderstorms.
AccuWeather meteorologists are monitoring another round of heavy rain that may arrive around the middle of next week.
