Plain English
What these alerts mean
A warning means the hazard is happening or about to; a watch means conditions favour it; an advisory is a lesser hazard still worth planning around.
Frost is expected on the ground. Cover sensitive plants overnight.
Sub-freezing temperatures are imminent. Protect tender plants and outdoor plumbing.
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.
Sub-freezing temperatures are possible. Be ready to protect plants and pipes.
Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.
Minor coastal flooding is expected, usually around high tide. Expect water on low-lying roads near the shore.
Sustained winds of 30 mph or more, or gusts to 45 mph, are expected. Use caution driving high-profile vehicles.
Significant coastal flooding is occurring or imminent, typically at high tide. Move away from low-lying shoreline areas.
Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.

Questions
About Stamford alerts
How do I get Stamford weather alerts on my iPhone?
Install Forecast Bar, add Stamford as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Fairfield 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 Fairfield County, the county Stamford sits in. 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.
