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 works

Risk, 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 works

One 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 works

How it works

From your sites to a warning, in minutes.

01

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.

02

Virga watches the weather

A site-specific forecast, scored against your thresholds for likelihood and severity, refreshed on schedule.

03

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.”
