Seasonal Driving Considerations
Mountain passes along this corridor can be treacherous from October through May, with chain requirements, road closures, and whiteout conditions at higher elevations. Summer brings its own challenges — afternoon thunderstorms are common above 7,000 feet, and construction season narrows lanes on key highways. Always check pass conditions before departing, and carry emergency supplies during the colder months.

At 147 miles, the Moses Lake to Seattle drive is short enough to complete in a single stretch. Still, check conditions along the route before you leave — a quick glance at live traffic cameras can confirm road visibility and surface conditions. If bad weather is forecasted for a narrow window, adjusting your departure by even an hour can make a significant difference in safety.
