StormChance — not just the forecast. How bad it's going to be.

Any weather app can tell you it's going to rain. StormChance tells you whether that rain icon is a light mist or an actual storm. Each day the app provides a forecast with an impact score, letting you gauge how bad the weather could be. In addition, each US region has video forecast provided by a real meteorologist, so nothing is left unexplained especially when the weather gets rough.

Weather Impact Estimator
This is what sets StormChance apart. Each day in your forecast is scored from 0 to 6 based on how disruptive the weather is likely to be. Minimal, Noticeable, Potentially Strong, Likely Severe, Severe/Dangerous, or Extreme. Every score carries a color-coded gauge or badge on the day it applies to, so one glance at the forecast and you know what days to pay attention to. Tap any scored day for a summary of why each day was rated to a certain level. Scores blend the forecast with official severe weather and precipitation outlooks, that update as better information comes in.
