LOUDOUN COUNTY, Va. — A portion of roadway in Loudoun County is closed due to high water in the area, officials said. The Loudoun County Sheriff's Department said Shreve Mill Road is closed in both directions between Sycolin Road and the Dulles Greenway due to the high water.
The Baltimore-Washington National Weather Service said it's expecting locally heavy rain and showers Saturday through the mid-morning.
The sheriff's office tweeted to never drive through areas where the water covers the road.

The area will dry out Saturday afternoon except for a stray shower. There will also be some mountain snows Saturday night and Sunday.
With the cold weather this week in the DMV, you may have noticed the low pressure light go off in your car.
When it's cold outside, the air is dense and the molecules are more closely packed. This creates lower pressure. So in the winter, you need to make sure you add air in your tires and keep them properly inflated.
What's the result of under-inflated tires? It can have a surprisingly big impact on your chances of hydroplaning during rain.
An under-inflated tire means you have less pressure pushing it down on the road. Therefore, you have less tire-to-road contact than a properly inflated tire. This increases your risk of hydroplaning.
Your car will tell you the proper pressure that the tires should be. But let's break down some numbers on the effect of under-inflated tires on the risk of hydroplaning.
