Johnson County's EF4-5 history

What a storm shelter costs near Johnson County
For a Johnson County homeowner, budget $2,890-$13,280 for a shelter or safe room ($7,645 typical) - this pass found no Texas-specific rebate on top of FEMA's underlying 75% national cost-share program.
The outage nobody plans for
210,547 people live in Johnson County, and a tornado outbreak's power loss usually reaches far more of Texas than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
Check your coverage, not just your risk
Because Texas allows wind/hail exclusions on standard homeowners policies, a Johnson County homeowner should confirm tornado wind damage is actually covered, not assume it - a separate endorsement is common here.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Johnson County covers about 725 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. Pre-radar-era records (before the 1990s) are also documented by NOAA as undercounting weaker tornadoes in sparsely-instrumented areas. Johnson County has about 210,547 residents.
