Rain in Annandale: What You Need to Know
Annandale, Virginia experiences mid-Atlantic nor'easters and sea level rise flooding. The Annandale rain radar provides real-time precipitation data at up to 250-meter resolution, updated every 4–6 minutes from KLWX (Sterling VA) / KAKQ (Wakefield) — giving residents, commuters, and outdoor workers the advance notice they need before conditions change. A hyperlocal radar shows the actual cell position over Annandale; a forecast shows a probability across the broader Virginia region.
Storms in Annandale's part of Virginia typically approach from northeast or southwest. RainViewer's live map includes direction arrows that track exactly where an incoming cell is heading, so you can see whether rain will reach your neighborhood in Annandale or pass to the north or south. The 2-hour nowcast adds a forward-looking view beyond what the current radar frame shows.
Rain by Season in Annandale
Peak rain season (June–September (convective+tropical) and October–April (nor'easters))
Annandale's most active weather aligns with June–September (convective+tropical) and October–April (nor'easters), when mid-Atlantic nor'easters and sea level rise flooding drives the primary precipitation risk across this part of Virginia.

- Does Annandale flood when it rains heavily?
Annandale, like most Virginia communities, can experience localized flooding during intense rain events — particularly in low-lying areas near drainage channels, road underpasses, and stream corridors.

- When is the rainy season in Annandale?
Annandale's primary rain season runs through June–September (convective+tropical) and October–April (nor'easters), driven by mid-Atlantic nor'easters and sea level rise flooding. The driest period is typically January–February, when precipitation probability is lowest and outdoor activities carry less weather risk.
