Update at 12:30 p.m. — The National Weather Service has now upgraded central Fairfax County and the City of Fairfax from a flood watch to a flood warning, which will remain in effect until 4 p.m.
As of 12:03 p.m., between one and two inches of rain have fallen in the county, and an additional one to two inches of rain could potentially fall in the area covered by the flood warning. Reston is among the locations considered at risk of flooding.
Earlier — A Flood Watch is in effect for most of the region until 10 p.m. today, according to the National Weather Service.
Remnants of Hurricane Zeta are expected to dump two to three inches of rain on the area.
NWS warns that heavy rain could lead to flooding of small streams, creeks, and urban areas. Clogged drains due to leaf buildup might also cause flooding issues.
Here’s more from the alert:
Do not enter or cross flowing water or water of unknown depth. Stay away or be swept away. River banks and culverts can becom unstable and unsafe.
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.
