See how we choose, source and review every alert, estimate and safety guide we publish

What we publish

Live pages show official alerts, storm positions and readings, plus our estimate of what they mean for a place and what to do. Guides explain how to prepare for, ride out and recover from extreme weather.

Sources

Every instruction links to the official source it is based on: the National Weather Service, National Hurricane Center, Storm Prediction Center, Weather Prediction Center, FEMA and Ready.gov, or your own state and county emergency management. We do not invent warnings, and we do not repeat unverified social media reports. See the source list.

Review before indexing

A guide is submitted to search engines only after it has been checked line by line against its cited official source. Guides that have not completed that check stay readable but are marked noindex.

What we do not do

• We do not tell anyone to evacuate or to stay. That is decided by local officials.
• We do not use fear or exaggeration. Levels use fixed rules, and a place with no active hazard is shown as low.
• We do not let advertising influence content. Ads, if any, come after the information and never sit inside alerts or action lists.

Corrections

Verified errors are fixed quickly. See corrections and feedback, and the methodology for how impact levels are set.
