How this works

About these pages

Forecast Bar polls the National Weather Service alert feed continuously to deliver push notifications to its users. These pages are the same feed, organised by place: one page for each of the 3,234 counties and county equivalents, one for each of the 800 cities of 50,000 or more, and one for every state and territory. Each page shows the alerts in effect, in plain English, with a map, the last 30 days, and a running 12-month count by alert type.

Every page is also available as JSON by adding .json to its address, for anyone who wants the data in their own tools. Canada has the same pages, built from Environment and Climate Change Canada's alerts.

To get any of these alerts on your phone the moment they are issued, install Forecast Bar and add the places you care about.

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.

Small Craft Advisory

Winds or seas hazardous to small boats. Inexperienced mariners should stay in port.

Flood Warning

Flooding of rivers, streams or low-lying areas is occurring or expected. Avoid flooded roads and monitor river levels.

Frost Advisory

Frost is expected on the ground. Cover sensitive plants overnight.

Dense Fog Advisory

Visibility of a quarter mile or less is expected. Slow down and use low beams.

Extreme Heat Warning

Extremely dangerous heat. Avoid strenuous activity, stay in cool spaces and never leave people or pets in a vehicle.
