The dollar figure Aleutians East Borough's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Alaska has no state rebate program confirmed here; FEMA's underlying 75% cost-share exists nationwide, but applying through a state program is what usually makes it real, and none was found for Alaska this pass.
What a direct hit isn't required for
3,632 people live in Aleutians East Borough, and a tornado outbreak's power loss usually reaches far more of Alaska than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What this number is, and is not
One caveat before relying on Aleutians East Borough's number: it is county-wide, and it covers about 6,985 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. Aleutians East Borough has about 3,632 residents.
