KPCC reporter Molly Peterson spoke with a meteorologist from NOAA (National Oceanic and Atmospheric Administration). He explained how they monitor weather conditions in fire areas. They use RAWS, or Remote Automated Weather Stations, to monitor humidity, temperature, and other data points.
They use this information to inform and adjust their weather models day by day, putting these devices out in the field and then bringing them back in. A member of their crew takes humidity samples all day and then brings them back to a fire behavior analyst to crunch the numbers and adjust their computer model.
