How to read it. Colors are the exact hues the NWS uses on its public hazards map, so a tile here matches what you
see on a warning map or on any weather.city forecast. The small code (e.g. TOR) is the product's
identifier; the corner number is the live count of that alert in effect nationwide. Warnings mean act now,
watches mean be ready, advisories mean be aware. Counts refresh from the live NWS alert feed.
People affected sums the Census population of every county under each alert (2026 estimates). Because a
single county is counted whole even when an alert covers only part of it, these figures are a generous, county-level tally —
a good sense of scale, not an exact head-count. Marine zones and a few territories carry no county population.
