FAIRFAX COUNTY, VA -- The National Weather Service Tuesday morning has issued a Flood Watch for the region, including Fairfax County.

Here’s the announcement just in Tuesday morning from the NWS:

Through Tuesday evening, a low pressure system will move across the region. This will result in rain, which will be heavy at times during the first half of the day. Rainfall totals across the watch area are expected to range between 1 to 1.5 inches.

This heavy rainfall, coupled with snow melt will lead to the potential of small streams and tributaries in the watch area to overflow their banks.

Urban areas prone to poor drainage will be susceptible to flooding, according to the NWS. The time of the greatest threat of flooding will be from Tuesday afternoon through Tuesday evening, according to the weather service.

Precautionary actions

A Flood Watch means there is a potential for flooding, based on current forecasts. You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop, the NWS warns.

Patch will update this story Tuesday if new information becomes available.
