Seasonal Hazards Dashboards

Seasonal Summer Hazards

The seasonal summer hazards dashboard shows trends in emergency department (ED) visits in Washington state for asthma, drownings, heat-related illness, recreational boating injuries, and smoke exposure alongside temperature and air quality data. The data are compiled from RHINO and are presented at the State and County level. All relevant ED visits in Washington are included, regardless of where the patient resides.

Why Is This Data Important?

The data on this dashboard helps us monitor the healthcare impact of seasonal hazards (including temperature and poor air quality) in near-real time during seasonal events (such as the 2021 Heat Dome) across time and by Washington county.

Please note, the maps and time series for 2024 include data from 5/1/2024 onwards only. Data in the time series for 2024 is sparse resulting in wide axes. As more 2024 data fills in, the time series axes will auto-adjust accordingly. Please contact the RHINO team at with any questions.
