Site-level weather risk & alerts
Not just a forecast. A warning system.
Virga tells you when the weather puts your operation at risk. Get clear, custom alerts on the thresholds that matter, across one site or 50.
Weather risk, not just a number
A forecast tells you the weather. Virga tells you the risk.
A traditional forecast hides what you really need. Virga scores against your personalized thresholds, then alerts you to make a clear decision.
- How likely and how severe, on every alert.
- Confidence that scales with lead time.
- Thresholds set per site, not a generic warning.
Why it matters
The right platform is the difference between guesswork and confidence.
Narrow your coverage area, personalize your thresholds, customize your alerts and put it all together to make the right decisions, again and again.
The platform
Weather turned into a decision.
Alerts on your thresholds
Set what counts as risk for each site, wind speed, moisture, temperature, snow. Virga watches every site and warns you the moment one crosses the line.
How it worksRisk, not just a forecast
Every alert comes with how likely the risk is and how severe it could get, plus the confidence behind it, so you know how much to trust the call before you act.
How it worksOne view, every site
A calendar monitor across every site you manage, and an AI assistant that turns dense data into a straight answer. Virga scales the view without scaling the guesswork.
How it worksHow it works
From your sites to a warning, in minutes.
Add your sites and thresholds
Enter each site by address, city, or ZIP, and set what counts as risk for it. Virga builds a station for that location, no hardware to install.
Virga watches the weather
A site-specific forecast, scored against your thresholds for likelihood and severity, refreshed on schedule.
Act on the alerts
Get warned early, see every site on one calendar, and ask the assistant what it means for the day ahead.
The forecast engine
How ClimateSync™ works
Every forecast model has strengths and weaknesses. ClimateSync™ calibrates each one against how it has actually performed, fine-tuning temperature with statistical methods and correcting precipitation against real-world outcomes, so the system doesn't just repeat the models; it corrects them to better match reality.
Runs in the browser. Nothing to install. Works alongside the tools you already use.
“A forecast tells you the weather. Virga tells you the risk.”
Built for operations
Enterprise-ready. Site-specific.
Thresholds that fit your risk
Custom alerts for wind speed, moisture, temperature, or whatever puts your operation at risk, set per site.
One calendar, every site
Track weather risk across every site you manage, days out, in a single view.
Fits your existing stack
A REST API delivers site-level forecasts into the dashboards, schedulers, and systems your team already runs, with API keys and OpenAPI docs.
