How big was the hail on October 30, 2024?

The maximum estimated stone size anywhere in the country that day was 1.00 inches, over West Albany, NY. Sizes vary street to street inside a single swath, so a city's figure is the largest radar estimated anywhere within about 5 miles of it.

Where does this hail data come from?

NOAA MRMS radar, specifically the Maximum Estimated Size of Hail product, ingested directly from the public NOAA archive. It runs about a quarter of an inch against ground truth, which makes it good for deciding where to look and not a substitute for an inspection.

Does this mean roofs were damaged?

Radar measures stone size, not damage. Whether a particular roof was damaged depends on stone size, wind direction, roof age and material — only an inspection settles it. These figures tell you where it is worth looking.

How do I see the actual swath on a map?

A HailMate plan puts a whole state on a real interactive map, with this swath and three years of others already on it. From $79/mo, and the canvassing tools come with it.
