The BLM – Alaska Fire Service   Initial Attack Management System (IAMS) is suite of computer applications developed by BLM/Fire to aid dispatchers and fire managers. IAMS Maps is one of these applications and provides graphical representation of various kinds of geographic data. Maps has been modified to produce output to a Web site to allow internet access to the data that IAMS stores. Dynamic data such as lightning (available May – September), fires, etc. are updated at the homepage of the BLM – Alaska Fire Service  (select Maps / AFS IAMS Maps Viewer) every 15 minutes during the fire season.

Very high to extreme fire indices were reported in Oregon, California, Idaho, Utah, Nevada, South Dakota, Wyoming, Indiana, Alabama, Georgia, Kentucky, Tennessee, and Texas.

The low pressure currently along the west coast will produce strong easterly winds and low relative humidities as high pressure builds in behind it. A cold front moving through Colorado, Arizona and New Mexico will produce gusty northwest winds and cooler temperatures along with scattered showers and thunderstorms. Montana and Wyoming will become dry with cooler temperatures and gusty northwest winds. The Northwest will have cooler and more stable air.
