Frequently Asked Questions
What does Severe Weather measure?
Severe Weather prevalence is the number of people impacted by severe weather that could affect health and safety, such as heat, cold, freezing and humidity, in a neighborhood. It gives an idea of how many people's health is affected by the weather in an area at a given time, not just how comfortable the weather is.
How is Severe Weather prevalence reported in the Fresno area?
Severe Weather prevalence in the Fresno area is reported as the weekly score of how many people are impacted in a typical neighborhood in the area, on a five-point scale: Low (<5), Moderate (5–15), High (15–25), Very High (25–40) and Extreme (>40). The score reflects the number of people impacted by Severe Weather in a typical neighborhood in the area, validated against public health data from CDC, HHS, EPA, NOAA, and other authoritative sources. Methodology details are available at https://www.hubbubworld.com/intelligence#methodology.
What methodology does Hubbub use to calculate Severe Weather prevalence?
Hubbub develops proprietary models on top of geographic, demographic, environmental, surveillance and weather data to produce prevalence scores across the U.S. Prevalence is reported on a five-point scale (Low, Moderate, High, Very High, Extreme) so the scores are interpretable without needing the raw underlying numbers. The full methodology — including the modeling approach, validation against authoritative sources, and known limitations — is documented at https://www.hubbubworld.com/intelligence#methodology.
