Risk Overview
About Natural Disaster Risk in Webb County, Texas
Webb Faces Elevated National Risk
Webb County scores 89.25 on the composite risk scale, ranking as relatively moderate and far exceeding the Texas state average of 49.00 by 40 points. This places Webb among the highest-risk counties nationally, with exposure levels in the top tier.
Webb's High Standing in Texas
Webb County ranks as one of the highest-risk counties in Texas, with only a small number of counties scoring above its 89.25 composite score. The county's Lower Rio Grande Valley location and geographic exposure drive this elevated risk profile.
Webb Compared to Regional Peers
Webb's 89.25 score is among the highest in the region, exceeding Victoria County (86.48) and dramatically surpassing Val Verde County (76.08). Webb stands out as the riskiest county in this geographic cluster, reflecting its unique vulnerability to multiple hazard types.
Webb's Most Serious Hazards
Flooding dominates Webb County's risk profile with a score of 91.03, making it the county's defining natural disaster threat. Hurricane risk reaches 85.73 and tornado exposure sits at 76.91, creating a multi-hazard environment where water-related disasters are the primary concern.
Protecting Your Webb County Home
Flood insurance is absolutely essential in Webb County—standard homeowners policies exclude flood damage, and elevation risk is significant along the Rio Grande and in flood-prone neighborhoods. Pair this with windstorm coverage for hurricane protection and keep emergency supplies on hand, as Webb faces recurring exposure to both flooding and tropical systems.

Risk Verdict
At the 89th percentile nationally, Webb County sits in the upper half of U.S. counties for natural disaster exposure. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Webb County residents.
Hazard Breakdown
Flood risk is Webb County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 86th percentile nationally. Additional tracked hazards include tornado (77th percentile), wildfire (64th percentile), earthquake (44th percentile).
Preparedness Context
At the 91th percentile nationally for flood risk, Webb County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. Secondary hurricane exposure at the 86th percentile adds a second preparedness layer; households should review coverage options and alert sign-up for both hazard types. A tested family preparedness plan specific to Webb County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.
Regional Context
The Texas county average is 40.2 composite points below Webb County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
