Flooding possible in Southwest Virginia as remnants of Sally bring rain to the region

Digital Weather Specials

ROANOKE, Va. (WFXR) —The remnants of Sally are tracking into South Carolina this Thursday and Friday, and Southwest Virginia is seeing widespread rainfall as a result of this system. As pockets of moderate to heavy rainfall move into the region, flooding is a concern for portions of Southside Virginia.

The National Weather Service in Blacksburg has issued a Flood Watch for Charlotte, Halifax, Pittsylvania, Franklin, Henry, and Patrick counties (including Danville and Martinsville) for Thursday into Friday. These areas could see anywhere from 2 – 4″ of rain and flood-prone areas (low-lying spots, along creeks and streams, and areas with poor drainage) may experience issues.

If you’re traveling this Thursday, remember to never drive through flooded roadways. If possible, plan out your commute. If you know of a road or area that is prone to flooding, avoid using the route if possible.

If you live in a spot that is prone to flooding when heavy rainfall impacts the area, move to higher ground when flood alerts are issued.

The National Weather Service in Blacksburg may issue flood alerts as rain continues to move in. It’s important to know what various terminology means.

Flood Watch:

  • means that conditions are favorable for flooding. This alert usually encompasses several counties and/or parts of an entire state(s). A Flood Watch can be in effect for anywhere from several hours or even several days. It simply means to be vigilant about the potential for flooding.

Flash Flood Watch:

  • means that conditions are favorable for heavy rainfall that could produce quick flooding. As with a normal Flood Watch, this alert can have an areal coverage of several counties and/or parts of an entire state(s). This alert can be placed in effect for a few hours to as long as a day or two. It, too, means that you should be aware about the possibility for flash flooding.

Flood Warning:

  • refers to a call to action to prepare for flooding that is imminent or is already occurring. Usually, this alert is for either a county or two or parts of a county. This alert can be placed in effect for a few hours or even several days after a rain event has occurred, but flood waters are lingering.

Flash Flood Warning:

  • like a regular Flood Warning, this alert means that flooding is either imminent or is already occurring. It is also typically placed in effect in the midst of a heavy rain event that’s causing rapidly-rising flooding. This alert is usually in effect for a time of as little as 30 minutes or as much as several hours. Action should be taken to protect life and property.

Flood Advisory:

  • is placed in effect during an active rainfall event where flooding is possible, but doesn’t quite meet the criteria for a Flood Warning. This alert usually runs from as little as 30 minutes to as much as several hours and can encompass an area from part of a county to a few counties, depending on the area adversely affected by flooding.

Flash Flood Emergency:

  • this is the highest alert issued for flooding. It means that flooding is occurring and has become a threat to life and/or property. Evacuation orders are likely in effect for flood-prone areas. Actions to protect life and property is necessary. This alert can be placed in effect for as little as 30 minutes to as much as several hours and is usually limited to small locations, possibly as small as part of a city and/or town or as much as a county or two.
