The BLM – Alaska Fire Services 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.

Regarding the INCIDENT MANAGEMENT SITUATION REPORT the current situation for 29 July 1999 can be quoted as follows:
Increased initial attack activity was reported in the Eastern Great Basin Area. Minimal activity was reported elsewhere with one new large fire reported in the Northern Rockies Area. Containment was accomplished on a large fire in California. The National Interagency Coordination Center mobilized a caterer, shower unit, lead plane, air tankers, helicopters, infrared aircraft, telecommunications equipment, crews and miscellaneous overhead. High to extreme fire indices were reported in Oregon, Washington, California, Montana, North Dakota, Idaho, Utah, Nevada, South Dakota, Wyoming and New Jersey.

A fire weather watch is in effect over Montana for increasing winds, low humidities and dry lightning.
High pressure aloft continues to dominate the weather across the western part of the country. Monsoon moisture will continue to move north out of the southwestern United States. An upper level trough and low pressure system along the west coast will keep the interior Pacific Northwest, California valleys and much of the Great Basin dry and very warm.
Colorado, Utah, New Mexico, Montana, Wyoming, and Idaho will have isolated to scattered afternoon and evening showers and thunderstorms. This activity will be prevalent over the mountains. Utah and Arizona may experience heavy rain with the thunderstorms.
Portions of Montana, Nevada, eastern Oregon, Wyoming and western Idaho may experience isolated dry thunderstorms today.
The rest of the western states will be dry with mostly sunny skies, except for continued morning low clouds and fog along the California, Washington and Oregon coasts. High temperatures will be in the 80’s to near 100 in most locations, with 60’s and 70’s in the mountains. Temperatures in the southern deserts will be in the 90’s to 110.
Eastern Oregon, eastern Washington, western Idaho, and Nevada will see relative humidities drop to near 10 percent in the afternoon.
