Typhoon season is year-round; however, most typhoons form from early July through mid-December.
Most typhoons scrape or strike places like the Philippines, Japan and Taiwan; they can also hit the Korean Peninsula, China and Vietnam, bringing damaging winds and storm surges.
Typhoons have also hit U.S. territories, causing billions of dollars in devastating damage to places like Guam, which was battered by Super Typhoon Mawar in May last year.
Where will it rain?
Flash flooding can occur well inland and away from the storm’s center. Even weaker storms can produce excessive rainfall that can flood low-lying areas.
