There are only two weeks until the total solar eclipse of Aug. 21, 2017. If you're traveling into the path of totality, it's time to make sure your plans are in order.

The Aug. 21 total solar eclipse will sweep across the continental U.S., beginning in Oregon and ending in South Carolina. The last time an eclipse touched both American coasts was in 1918. Eclipse enthusiasts say this phenomenon is one of the most spectacular sights in nature. As a sort of celestial preview, the moon will pass through part of Earth's shadow in a partial lunar eclipse today (Aug. 7).

Skywatchers throughout the U.S. will be able to witness a partial solar eclipse on Aug. 21, when the moon covers less than 100 percent of the sun's disk. But only skywatchers inside the path of totality will see the incredible phenomenon of a total solar eclipse. Wherever you will be, it's a good idea to have solar viewing glasses on hand. Or, you can build your own pinhole camera to watch the moon's progress across the sun. [Where to See the 2017 Total Solar Eclipse, State by State]

You can use this interactive eclipse map to find out exactly where totality will be visible, as well as when totality will occur at different locations inside the path. Totality will last for less than 3 minutes depending on how close you are locatedto the center line, so make sure you are looking skyward at the right time!

If you plan on traveling to see totality, be aware that experts are expecting nightmarish traffic conditions. Plan for extra time to reach your destination. Many cities and towns along the path of totality are planning eclipse-related events that could cause additional traffic delays. Research your destination ahead of time to find out where to park and where to observe the eclipse.

Massive crowds are expected to converge on the path of totality, and members of the American Astronomical Society (AAS) Eclipse Task Force have suggested that people driving to the path of totality should have food, water and a full tank of gas, in case you find yourself stuck on a highway for an extended period. When you reach your destination, be aware of where you can find additional supplies, as well as bathroom facilities. People who live inside the path of totality may also want to stock up on basic supplies and gasoline.

Due to the somewhat unique nature of this event, hotel rooms in the path of totality are difficult to come by, and those that are still available are often very expensive. However, travelers may still be able to find campgrounds and RV parks inside the eclipse path with room to spare. Alternatively, travelers could consider renting a room or a private home through the website Airbnb.com.

Whatever your eclipse plans are, now is the time to solidify any travel plans and get your eclipse-viewing equipment. Don't miss this incredible opportunity!
