Clearing skies and light winds Friday night could lead to some fog mixing with residual smoke in the Clackamas River valley, reducing visibility Saturday morning.  As Saturday begins to warm up, smoke/fog is expected to clear from the north, moving up river.  Air quality levels at the start of the race are expected to be in the Moderate range [ Air Quality is acceptable for most. There may be moderate health concern for a small number of sensitive people ] and should improve throughout the day. Below is an air quality chart for Estacada over the last week for comparison with what you may have observed in the area.

We expect Saturday morning to be a little hazy and smoky at the start line at 10 am, clearing gradually as the runners/walkers continue north along the race route.  As always, use your best judgement to determine if conditions are favorable for your planned level of exertion. Smoke forecasts for the areas of highest impact are presented below - darker colors indicating the highest concentration of smoke.  Models are calling for improved conditions along the race route for Saturday morning, but some residual smoke may still be present in the river valley. 3 pm Thursday, September 25, 2014   8 am Friday, September 26, 2014   8 am Saturday, September 27, 2014 Noon Saturday, September 27, 2014
