The following airports in Washington state provide commercial passenger and/or general aviation services:

Time Zones: The state of Washington and the airports listed above are in the North American Pacific Time Zone. Pacific Standard Time (PST) is eight hours behind Greenwich Mean Time/Universal Coordinated Time (GMT/UTC). The Pacific Time Zone is three hours behind the Eastern Time Zone (Boston, New York, Atlanta, Miami). Beginning in 2007, clocks will be advanced at 2:00 am on the second Sunday of March to go on Pacific Daylight Saving Time (PDT) which is seven hours behind GMT/UTC. Clocks return to standard time on the first Sunday of November.

The web site maintained by National Institute of Standards and Technology (NIST) and the U. S. Naval Observatory (USNO) displays the official times for zones in North America and American Territories.  This site also provides information about these times zones and others around the world.  The National Atlas has a very good map showing time zones in the United States. 

Road Conditions: The web site published by Washington's Department of Transportation is an excellent source for highway conditions.  This web site also provides links to web sites for the transportation departments in Oregon.

Weather:  For weather conditions and forecasts for these airports and other parts of the United States refer to the web site published by the National Weather Service.  

Maps:  The National Geographic web site and its Map Machine have excellent maps for this state and other locations around the world.  The Perry-Castañeda Library Map Collection at the University of Texas has on-line maps for this and other states.  The Washington Department of Transportation has a collection of very useful maps to assist with travel planning.  Click on "View Map" for a statewide map on line.  The National Atlas has useful maps showing states, counties, geographical features and other interesting data for the United States and Puerto Rico.  The best options are for "Printable Maps" (use PDF format) and "Dynamic Maps." The U.S. Department of Transportation Federal Highway Administration also has a map showing major highways in the state.

Travelers should be aware that in late fall, winter and early spring passes crossing the Cascade Mountains is subject to heavy snow and ice conditions, so it is important to check weather and road conditions at this time.  Consideration should also be given to flying to an airport that will preclude a need to cross the Cascades by road.  This mountain range runs north and south through Oregon and Washington to the east of Portland, Salem, Eugene and Medford in Oregon and to the east of Seattle, Olympia and Vancouver in Washington state.
