The United States Geological Survey (USGS)sometimes issues debris flow advisories for parts of coastal California-much like the severe weather forecasts or flood forecasts that are issued for other regions of the country.Which one of these factors is the USGS unlikely to consider important in forecasting the likelihood of debris flows?

Question

The expected air temperatures are unlikely to be considered important in forecasting the likelihood of debris flows. While temperature can affect the rate of snowmelt and therefore influence water runoff, it does not directly impact the conditions that lead to debris flows. Factors such as forecasted rainfall, the steepness of slopes, and the seasonal and diurnal variation in water uptake by plant root systems can all play a role in determining the likelihood of debris flows.
