LARGE FIRES IN NORTHERN ROCKY MOUNTAINS CONTINUE; HURRICANE IRMA

Several fires burning close to the borders of Montana and Idaho are causing large, heavy smoke plumes spanning the north central and north west regions of the country (HMS, top left). Collectively, the fires have burned more than 12,000 acres. The smoke produced is having clearly visible from satellite, shown by the NASA WorldView image (top right). All this smoke is having a clear affect on air quality index (AQI). The AirNow particulate matter AQI image for 09/03/2017 shows that AQI reached unhealthy levels (red) in the areas near the fires, and very unhealthy levels (maroon) in northern California (bottom left). Unrelated to the fires, hurricane Irma, expected to wreak havoc in the Virgin Islands and southeastern US, is seen forming via satellite (NASA Worldview, bottom right). Though the exact path is currently unknown, it's moving west toward the virgin islands.
