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.

What does a storm look like from above?
Satellite imagery helps determine the strength, size, and organization of a storm. The stronger the storm, the more likely it is to form an eye in the center. If the eye appears symmetrical, it often means the storm isn’t encountering anything that could weaken it.
Typhoon season occurs all year round, but most typhoons occur between early July and mid-December.
Many typhoons hit or pass through areas such as the Philippines, Japan, and Taiwan, and can also make landfall on the Korean Peninsula, China, and Vietnam, causing damage from 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.

Tracking Map Tracking data is provided by the National Hurricane Center and the Joint Typhoon Warning Center. The map shows at least a 5 percent probability. Forecasts are up to 5 days out, up to 3 hours before the storm is reported to reach its latest location. Wind speed probability data is not available north of 60.25 degrees north latitude.
Wind Arrival Table Arrival times are generated by New York Times analysis of National Hurricane Center data. Geographic locations are from the U.S. Census Bureau and Natural Earth data. Time zones are from Google. Table shows projected arrival times for specific cities that may be reached by sustained damaging winds of 58 mph or greater. If damaging winds reach a specific location, there is less than a 10 percent chance that they will arrive before the “earliest reasonable” time and a 50 percent chance that they will arrive before the “most likely” time.
