Pinpoint Weather: Off and on rain today, heavy rain and flooding possible as remnants of Fred approach Tuesday
There was record rainfall on Sunday as nearly 3” of rain was recorded at Roanoke Blacksburg Regional Airport as the heat wave ended. The issue with the rain was forecast, there was a decent amount of moisture available and the frontal boundary that meandered over the Commonwealth was the focal point for the rain. Of bigger concern is the rainfall that saturated the soil ahead of what will be another round of significant rain associated with the remnants of Fred.
The tropical moisture associate with Fred will arrive on Tuesday and add a good deal of rain to the saturated soils. The flow of air is going to be from the Southeast, and that will be meaningful as the mountains will be able to squeeze out as much of the rain as possible along the Blue Ridge escarpment. Areas along the ridge in Franklin, Carroll, Patrick, Bedford and Amherst counties will be impacted aggressively. The areas closest to the ridge may see flooding and flash flooding as the “upslope flow” along the east face of the mountains enhances rainfall rates. Everyone is going to get heavy rain and localized flooding, but areas in the mountains will be impacted greatly. Streams and creeks will be overtaken quickly and there is a good chance for widespread flash flooding in our hilly terrain.
The rain will continue through Wednesday and the relentless rainfall will take a toll. The larger rivers will not be impacted at the onslaught, but as the flow from the swollen creeks and streams make it to the larger rivers, they too will be looking at high rises. Needless to say, this will be a very dangerous next two or three days, especially for those living along or near flood prone areas. Make sure to seek higher ground in the event of flooding conditions and never drive over a flooded-out roadway.
Thursday and into the rest of the work week and into the weekend there will be warmer weather and scattered showers and thunderstorms.
