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.

Another upper level low pressure area will form off the pacific northwest coast which will generate scattered showers and thunderstorms along the Cascades.
High temperatures will be in the 60’s along the coast, mid 60’s to the lower 80’s in the mountains, mid 80’s to upper 90’s in the lower valleys of north and central Nevada, and near 105 in southern Nevada.
