Seattle ? A windy Pacific storm dumped heavy rain Monday on western Washington, killing at least one person, prompting warnings of record flooding and forcing rescues by the National Guard.

A 20-year-old elk hunter from Seattle died when his pickup truck was swept into the Cowlitz River in southwest Washington, authorities said.

Gov. Chris Gregoire declared a state of emergency for 18 counties, authorizing the National Guard to activate and the state Emergency Management Division to coordinate assistance.
