Typhoon season occurs all year round, but most typhoons occur between early July and mid-December.
Many of these typhoons will hit or pass over areas such as the Philippines, Japan and Taiwan, and may also make landfall on the Korean Peninsula, China and Vietnam, bringing with them damaging strong winds and storm surges.
Typhoons have also made landfall on U.S. territory, causing billions of dollars of devastation in areas such as Guam, which was hit by Super Typhoon Mawar last May.
Where will it rain?
Flash flooding can also occur inland, away from the storm’s center. Even weak storms can produce enough rainfall to flood low-lying areas.
