Grass Adjective Rating
Fuels & Fire Behavior ISI
• With winds dropping off around the
state, ISI values are fairly moderated.
Copper River Basin is the exception.
• Grass Adjective Rating shows fine
fuels in west and south have taken
enough rain…potential still exists in
east and northern Panhandle
• Precipitation is likely to moderate
conditions in east over the next
couple of days
Summary
Questions?Call 907-356-5691
• Long-term Forecast
– Disorganized pattern with
weak large scale systems
means a continuation of cool
and damp weather pattern
through the workweek
– Beyond that, models indicate
some improvement, but
pattern looks unstable so
confidence is low more than a
couple of days out
• Short-term Concerns
– Overall, lighter winds for
the next few days, breezy in
South Central, AK Range
– WET thunderstorm
potential in Interior
increases thru Thursday
– Temperatures will remain
cool, with 50s and 60s, and
only a few 70s where sun
breaks through for awhile
– Showers off and on around
the state through week
– Wet week in Panhandle
