Day two of significant flooding, this will be very active as we have reached saturation and any rain will lead to more flooding and landslides.
- Flash Flooding will continue to develop today and into the evening
- Flooded roads as some structures will be damaged by water
- Localized power outages will be possible as winds pick up 15-25 mph gusts
- Landslides remain a threat today and this evening
- Larger rivers will continue to rise above flood stage into the weekend
- Isolated storms may be strong to severe Friday afternoon in Southside
- Gusty winds the main threat, possibly some hail.
Today: Flash flooding will be an issue in the NRV where a warning has already been issued. We will start to get more specific information about the flooding spots. The flooding will creep up on folks so we need to continue to give them the info they need to stay safe. Any rain that falls on Thursday will be considered flooding rains as there will be no ability for the ground to absorb any more water. Flash flooding will be more likely in the NRV and Highlands as the terrain will enhance the runoff of the water. Landslides and debris flows are going to be more likely and there is also going to be some windy conditions along the mountains and the NRV which may easily push trees over as the root systems have been weakened by the rain. Power outages likely. Buildings will be starting to get threatened by the rain water. Roads will be dealing with debris and water; I expect a number of road closures.
Friday: We deal with the lag time flooding. The rain should be ending but this where we find the most issues with the Dan, New, James, Roanoke River in Roanoke, Staunton River as well as the Pigg. There will also be a threat of severe storms in the SE corner of our viewing area as the potential for gusty winds and hail may reach the severe limits of near 60 mph gusts and 1” hail. The rest of the region will see the potential for gusty winds but may not reach severe levels. This is a big issue as there will be a good chance for us to see trees pushed over and power outages may be more likely on Friday even as the rain tapers off.
Saturday will see some spotty rain but the opportunity for the larger rivers to be impacted by flooding as they are not expected to crest until this weekend.
All in all, this has been playing out as expected and the potential for dangerous widespread flooding should continue. Many roads closed due to high water and more will be closed today as the rain continues.
