Pages: 9 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink. Cards: print double-sided, flipping on the long edge, on thin card.

Every fact is checked against NOAA Storm Prediction Center, NOAA National Severe Storms Laboratory, US National Weather Service, Met Office, TORRO and ESSL web pages (checked 31 Oct 2026) and the sources are listed on each pack’s credits page. Facts that can change, such as yearly averages and records, are printed with that date. Photos are public-domain images from NOAA, FEMA and the US National Weather Service, via Wikimedia Commons; drawings, puzzles and layouts are REALLYBYTE’s own work. Not endorsed by NOAA, the National Weather Service, FEMA, the Met Office, TORRO or ESSL. This is an educational resource, not official emergency guidance: always follow your local weather service’s warnings.
