Forest Fires in the United States

12 October 1999


The National Interagency Fire Center reported on 8 October 1999 that California is the only state reporting large fire activity today, however, very high to extreme fire conditions were reported from Oregon, Utah, Idaho, Montana, Nevada, Indiana and Georgia as well.

Fire Weather Outlook
High pressure centered over the Great Basin will produce gusty Santa Ana winds up to 40 mph with very low relative humidity. Temperatures will range from the 90s to near 100 degrees around the inland areas of southern California.
A Pacific storm along the Canadian border will spread clouds and rain from the northern Oregon and Washington coasts into the Intermountain region today.

The National Interagency Fire Center displays the latest large wildland fire map of the United States on 8 October 1999. For more information please refer to the website of National Interagency Fire Center.

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.

The latest IAMS image of active fires in Alaska is shown in a map of 5 October 1999.

According the INCIDENT MANAGEMENT SITUATION REPORT the current situation for 11 October 1999 can be quoted as follows:

“…
CURRENT SITUATION
Minimal initial attack activity was reported from all Geographic Areas. New large fire activity was reported in the Rocky Mountain Area. Very high to
extreme fire indices were reported in Oregon, California, Utah, Idaho and Colorado.

OUTLOOK:
A weak Pacific cold front over western Washington and Oregon will move northeast through the northern Intermountain Region today with scattered showers and gusty winds to 30 MPH, especially in eastern Washington and northern Idaho. Maximum temperatures will range from the 50’s along the Pacific Northwest coast to the 60’s and 70’s inland. Minimum relative humidities will range from 50 to 80 percent along the coast with 15 to 40 percent inland.
High pressure will dominate the weather for the southern portions of the western U.S., resulting in dry conditions and normal daytime winds. After a few morning coastal clouds, sunny skies will prevail in California, Nevada and Utah. Maximum temperatures will range from the 60’s in the coastal areas, to the 70’s and 80’s inland, with 90’s in the inland southern California area. Minimum relative humidities will range from 50 to 70 percent along the coast, with 5 to 35 percent inland.
A stalled cold front extending from the mid Atlantic states through the eastern Gulf states will continue with scattered showers and thunderstorms over Alabama and Georgia. A weak high pressure system over Oklahoma and Texas will spread a dry and stable air mass across Louisiana, Arkansas and into Mississippi. Maximum temperatures will range from the 70’s through the 80’s. Minimum relative humidities will range from 70 to 80 percent in Alabama and Georgia, with 40 to 60 percent in Louisiana and Mississippi.
