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.
According the INCIDENT MANAGEMENT SITUATION REPORT the current situation for 5 October 1999 can be quoted as follows:
Minimal initial attack activity was reported from all Geographic Areas. New large fire activity was reported in the Eastern Great Basin Area. The National Interagency Coordination Center mobilized helicopters, infrared aircraft, an airtanker, a lead plane, radio equipment, dozers, and miscellaneous overhead. Very high to extreme fire indices were reported in Oregon, Washington, California, Idaho, Utah, Colorado, Indiana, and Georgia.
An upper level ridge centered over the Rocky Mountains will weaken as a mid-level storm system moves northeast over the northern Rocky Mountains. Winds from the west to southwest are expected to increase during the afternoon from eastern Washington and Oregon to the northern Rocky Mountains and south through the Great Basin. The continuation of onshore low level flow over the west will spread higher relative humidities further inland this afternoon, reaching the eastern slopes of the Washington and Oregon Cascade Mountains and south over northern California. Afternoon high temperatures will be cooler with valley highs mainly in the mid 50’s thru the 60’s, except in southern California which will be in the 70’s to mid 80’s. The mountain high temperatures will be in the mid 40’s and 50’s.
