Plain English
What these alerts mean

Flooding of rivers, streams or low-lying areas is occurring or expected. Avoid flooded roads and monitor river levels.
Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.
A heads-up about conditions that do not meet warning or advisory criteria but still deserve attention, such as a strong storm, patchy fog or a brief burst of snow.
Conditions are favourable for severe thunderstorms with large hail or damaging wind. Keep an eye on the sky and on warnings.
Heat index values high enough to cause heat illness with prolonged exposure. Drink water, stay in air conditioning and check on neighbours.

Questions
About Champaign County alerts
How do I get Champaign County weather alerts on my iPhone?
Install Forecast Bar, add Champaign County as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Champaign County then arrives as a push notification at the moment of issue, with Critical Alerts available for the most dangerous warnings. Forecast Bar also runs on iPad, Apple Watch, Mac and Apple TV.
Where do these alerts come from?
From the National Weather Service alert feed (api.weather.gov). NWS issues alerts by county and by forecast zone; this page lists every product that names Champaign County. Forecast Bar checks the feed continuously and this page refreshes within a few minutes of a change.
What is the difference between a watch, a warning and an advisory?
A warning means the hazard is occurring, imminent or very likely: act now. A watch means conditions are favourable for it to develop: prepare and stay informed. An advisory covers a hazard that is less serious than a warning but can still cause real inconvenience or danger if you are not ready for it.
