What drives it

Which part of the risk moves, and which doesn't

Among larger towns, Weed is at 71.8, while Yreka is 68.5 and Mount Shasta is 67.5. That keeps several market areas relatively close to each other, but not identical.

Each bar is what one part of the score covers across Siskiyou County, on the same 0–100 scale. A long bar is a part of the risk that depends on where you are; a short one is the same almost everywhere.

CAL FIRE has no mapped Fire Hazard Severity Zone at 92 of the 162 sampled points — the zones cover Local Responsibility Areas, and most of this county is state or federal land. At 92 of them the USFS grid above supplied the hazard reading instead.

162 sample points on a ~2.3 km grid, plus one at the centre of each community, weighted with the Satelife county profile v1 · median layer coverage 90%. Scores are 0–100 and comparable within the county, not across states.

For a property

What a county range means for one address

For property-level context, the countywide burn-probability model reports a mean annual burn probability of 1.44%, and its 90th-percentile cell is 3.47%. It also indicates 97.3% of the county can burn. This is a burn-probability view, not a fire-weather measurement.

Two local factors shown on this page are consistently elevated in many places: hazard-zone scores have a middle value of 87.2, and fire-history scores have a middle value of 70.0. The fire-history range runs from 5.0 near McCloud to 95.0 in unincorporated Siskiyou County.

For a home search or listing conversation, it helps to treat neighborhood differences as real: the gap between places like Tulelake (52.7) and Happy Camp (82.0) is large enough to matter in how wildfire risk is described.

Across 162 sampled points in Siskiyou County, the score runs from 23.9 to 85.3 — two neighbouring parcels can sit in different tiers. A county number is the middle of that spread; it says nothing about which end yours is at.
