What this means if you live in Austin: your area is in severe drought (D2) right now, and that's the single most active threat to a foundation here. If your home sits on expansive clay soil — common across much of TX and the broader South and Southwest — that clay is actively shrinking as it dries, pulling support out from under the foundation and opening or widening cracks. This is the season to watch for new cracks, doors that start sticking, and gaps at wall-floor joints, and it's the classic case where foundation watering (keeping soil moisture even around the perimeter) genuinely helps. What decides how hard these forces hit your specific lot is your soil type — see what actually moves a foundation for how soil, water, and construction interact.
What do the drought categories (D0–D4) mean?
They're the U.S. Drought Monitor's official national scale, released weekly: D0 is "abnormally dry," D1 moderate, D2 severe, D3 extreme, and D4 exceptional drought — the most intense. The percentage above is the share of your whole county sitting in D2 or worse, which is the range where expansive clay soils dry and shrink enough to stress a foundation. It's a real, current reading, not a historical average, so it changes week to week as conditions do.
Drought: U.S. Drought Monitor (NDMC/USDA/NOAA), most recent weekly release for Travis County. Freezing-day counts: NOAA National Centers for Environmental Information, 1991-2020 Climate Normals. Comparison figures are computed across the metros ClearPick tracks, not a national survey. The clay-shrink mechanism applies specifically to expansive clay soils; a local inspection is the only way to confirm your lot's actual soil and risk.
