WxYapper turns official forecast data into a plain-language briefing for planning. During severe weather—thunderstorms, tornadoes, flash flooding, high winds, and similar hazards—that briefing is helpful context, not a substitute for watches, warnings, or emergency instructions.
How to use the Summary tab when storms are in the picture, what “main concern” usually means, when to open Hourly and Daily detail, and where official alerts take over for life-safety decisions.
Start with the overview for the day’s story, then check main concern when it highlights storms, wind, flooding, or other hazards. Short-term detail often carries timing and trends from the forecast discussion. Treat that as planning guidance—when and why conditions may get awkward—not as a warning product.
For how each summary section works, see How to read a WxYapper forecast summary.
Use Hourly when you need timing for a commute, outdoor window, or when storms may arrive. Use Daily for the multi-day shape of the threat. These grids are still location-based forecast data—useful for planning, not a replacement for official warning polygons.
Do not rely on WxYapper alone when watches or warnings are in effect. Follow NWS products and local emergency guidance (weather radio, trusted local media, wireless emergency alerts). See the FAQ for more on safety and data sources.
