The month of July has yielded periods of flooding rainfall to much of the Korean Peninsula, and more is on the way.

The combination of a slow-moving frontal boundary and tropical moisture has led to rainfall nearly every day of July across the region.

Seoul, the capital city of South Korea, has reported rainfall on all but three days of the month. Rainfall has totaled 18.83 inches so far this month, more than 200 percent of normal.

More than 20 inches of rain has been reported in Pyongyang, the North Korean capital, also more than double the monthly average.

This extended period of rain has led to flooding and mudslides that have claimed the lives of several people in South Korea.

A round of heavy rainfall earlier this week claimed the lives of seven construction works due to the raging flood waters of the Han River.

Unfortunately, more heavy rains are expected as a slow moving frontal boundary continues to shift north to south across the peninsula into early next week.

The heaviest rain fell across North Korea earlier in the week before shifting into northern South Korea later Tuesday night into Wednesday.

A brief pause in the flooding rainfall is expected on Friday, before the front presses back into North Korea on Saturday. This front will stall near the border of North and South Korean leading to rounds of heavy rainfall from Sunday through Wednesday.
