(CNN) -- Record rainfall that flooded roads, subway lines and buildings has left two fishermen missing in northeastern South Korea, the Yonhap news agency reported Wednesday.
The rain started pouring Tuesday, as Koreans began heading home for Chuseok, a three-day harvest celebration.
Seoul received as much as 295 millimeters (11.6 inches) of rain, a high since record-keeping began in 1907, according to Yonhap.
As much as 100 millimeters (3.9 inches) of rain fell per hour in the capital, said the National Emergency Management Agency, according to Yonhap.
The two fishermen probably were swept away by rapids in Yeongwol county, Gangwon Province, 204 kilometers (127 miles) east of Seoul, said the emergency agency, Yonhap reported.
Flooding drove 11,8000 people from their homes, but most of them had returned by Wednesday, Yonhap said. Electricity also had been restored to up to 2,600 households.
Seoul's metropolitan government was to release $4.82 million in aid to flood victims.
