From Alert DC:
“The National Weather Service (NWS) has issued a Flash Flood Watch for the District of Columbia, which is in effect until 11AM Thursday, November 12, 2020.
Several rounds of moderate to heavy rainfall, with a few embedded thunderstorms possible, are expected to persist through Thursday morning. The first round is ongoing, with a lull expected later this afternoon. The second round comes this evening through tonight, with more moderate to heavy rainfall expected. Storm total rainfall of 2-4 inches is expected through Thursday.
Where heavier elements persist, we could see locally higher amounts. This could result in localized instances of flash flooding.
A Flash Flood Watch means that conditions may develop that lead to Flash Flooding. Flash Flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.”
