NWS flags Southside storm risk for damaging wind and heavy rain

Southside Virginia and the nearby North Carolina border counties should keep weather alerts close Tuesday as thunderstorms move through the region.

The National Weather Service Blacksburg office issued a Hazardous Weather Outlook at 4:13 a.m. Tuesday, June 23, 2026, for Pittsylvania County, Caswell County and nearby Southside Virginia counties. The outlook says there is a Marginal Risk of severe weather, with thunderstorms that may contain damaging winds and heavy rain leading to flash flooding.

This is an outlook, not a local warning. Conditions can still change quickly if storms strengthen, especially for drivers, outdoor crews, summer camps, evening recreation and residents in low-lying or poor-drainage areas.

• What to know: Marginal risk means isolated severe storms are possible, not guaranteed.
• Who is affected: Danville, Pittsylvania County, Caswell County and travelers on Route 29, Route 58 and nearby rural roads.
• Safety action: Move indoors if thunder is heard, avoid flooded roads and monitor later NWS warnings or local emergency alerts.

The Raleigh NWS outlook also notes weekend heat-index values of 100 to 105 for parts of central North Carolina, including Guilford and Forsyth, so Triad readers should begin planning for heat safety later this week.
