Event narrative

On the night of October 13, Tropical Depression 25W formed 1080 miles east of Guam. Twenty-four hours later on the night of the 24th, the depression intensified enough to become Tropical Storm Champi.

Tropical Storm Champi moved across the Marianas on the 16th, passing 65 miles north of Saipan during that afternoon.

Winds varied across the Marianas as some of the gusts occurred in shower bands south of the tropical storm. At Saipan, maximum sustained winds were 42 knots (48 mph) at 2 and 3 pm on the 16th with a peak gust to 68 knots (78 mph) at 1:32 pm. Lowest SLP was 991.6 mb

Rainbands associated with Tropical Storm Champi produced heavy rain in some areas. On Saipan at the International AIrport, 10.60 inches of rain fell on the 16th. This rain caused flooding, which damaged portions of Kanat Tabla Road on Saipan.

The inclement weather associated with Champi's passage caused the cancellation

or delay of several airline flights.
