All risk for the use of this information is assumed by the readers and users of this page, including those who use the results extracted from either this page, or the scripts on which this page relies. Never base decisions that could affect life, property, livelihood, or anything else, on the information contained on this page, whether this information is locally derived or extracted from other locations on the Internet. In particular, the outputs and results shown for the air quality index (AQI) and the text forecasts are entirely the experimental work of an amateur hobbyist with no training in either weather forecasting or meterology. As such, these pages could very well contain or convey completely incorrect information (for example, the AQI reading is based on the last measurement of pollutants only, and is not an average over multiple hours!)  
Current Conditions
Realtime Single-sample US-EPA Air Quality Index
56 - MODERATE

(Using 2024 US-EPA PM2.5 conversion)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
