A pesky frontal boundary has been hanging around Fredericksburg and DC for a while now… helping to produce some torrential downpours. A viewer sent me an email asking about the rain totals up there.
The map below from AHPS shows Fredericksburg is 4 to 8 inches above average for the just the past two weeks. It’s the area I’ve circled in yellow. That rain has saturated the soil and it’s why the NWS has put up a Flood Watch again for Northern Virginia. A big thunderstorm with just 1″ of rain could bring some creeks and streams out of their banks.
You’ll also notice some big surpluses along the NC state line.
Keep in mind the map isn’t total rain, it’s total rain departure over the past few weeks.
