Tropical Rainstorm Meranti will produce localized flooding over Honshu, Japan Sunday.

Meranti made landfall as a minimal typhoon Friday morning, local time, near Shishi, China. Maximum sustained winds were near 80 mph (130 kph). Meranti quickly weakened over eastern China, though not before unleashing widespread rain amounts of 2-4 inches (50-100 mm) across the flood-wary region.

Meranti continued to move northward and eventually northeastward and took aim at the Korean Peninsula. Very heavy rain started to fall over the peninsula Friday, local time, and persited through much of the day Saturday.

Widespread rainfall amounts exceed 2 inches (50 mm), while local amounts reached near 6 inches (150 mm). This heavy rain prompted flood warnings across the country.

Now moving east-northeastward, Tropical Rainstorm Meranti will spread heavy rain across Japan's main island of Honshu through the day Sunday, local time.

Widespread rainfall amounts of 2-4 inches (50-100 mm) will occur, triggering life-threatening landslides and deadly floods.

Conditions will gradually improve Monday as Meranti moves away from Japan.
