Arlington County is bracing for a yet another significant snowstorm, with forecasters calling for up to 8 inches of accumulation Thursday.

Arlington’s Dept. of Environmental Services says they will have all 50 of their snow-clearing trucks ready to clear Arlington’s 974 lane miles of roadway. So far, the department does not have an estimate for when crews will be able to move from clearing main roads to residential streets.

“We are closely monitoring the weather and will have our full resources (approximately 50 trucks) available,” said DES spokeswoman Shannon Whalen McDaniel. “The actual amount of snow that falls and the duration of the event (how long it falls) will dictate when our trucks can move from Phase 2 of clearing Primary Routes to Phase 3 – Residential Streets. We will notify the community when we shift phases.”

Whalen McDaniel said the heavy rain that’s expected today (Wednesday) will make pre-treating roads virtually impossible.

The National Weather Service, meanwhile, has issued a Winter Storm Warning for Arlington and the D.C. area.
