How Titus County floods

Flash flooding driven by severe thunderstorms dominates the flood profile of Titus County, accompanied by occasional tropical system impacts. Over the last 30 years, NOAA records show 28 flash flood events and one tropical storm event.

Recent occurrences include persistent supercell thunderstorms on June 8, 2025, and severe thunderstorm clusters that developed late in the afternoon on April 26, 2024, producing large hail and damaging winds across the region. Additional heavy rainfall was driven by an outflow boundary on May 13, 2023.

National Flood Insurance Program claims data indicates historical payouts across different zones. Zone X recorded 3 claims with an average payout of $158,981 and an average recorded water depth of 1 inch. Zone A recorded 2 claims with an average payout of $44,949 and an average recorded water depth of 1 inch. Zone X_UNSHADED recorded 1 claim with a $0 payout and an average recorded water depth of 0 inches. Homeowners and real estate agents in both designated high-risk flood areas and moderate-to-low risk zones should pay close attention to these localized flash flood risks.

From the storm reports

Flash Flood · Jun 8, 2025. Multiple supercell thunderstorms developed along a broad, diffuse baroclinic boundary across Northeast Texas throughout the day on June 8th. MLCAPE values were in excess of 4500 J/kg in proximity to these thunderstorms, with modest northwesterly mid-level flow contributing to 45 knots of effective bulk shear. Given the very weak convective inhibition, these thunderstorms persisted for several hours from early afte…

Flash Flood · Apr 26, 2024. A large cluster of strong to severe thunderstorms developed across Northeast Texas late in the afternoon on April 26th. These thunderstorms formed on the north side of a weak surface theta-e gradient, with southwest winds just off the surface aiding in warm air advection and inflow across the region. This cluster of thunderstorms maintained severe intensity for several hours with numerous reports of large hail and…

Flash Flood · May 13, 2023. An outflow boundary from early morning storms extended south from Eastern Oklahoma into East Texas by the afternoon hours on May 13th, while an upper low pressure area remained stationary near the South Texas coast. Strong daytime heating within a moist air mass in place contributed to moderate instability that developed during the afternoon, with widely scattered showers and thunderstorms igniting near and east o…

Flash Flood · May 8, 2019. A strong upper level trough of low pressure extending from the Intermountain West into the Four Corners Region energized the southwest flow aloft across the Southern Plains during much of the day on May 8th, with a strong low level jet sustaining a mesoscale convective complex (MCS) across much of Oklahoma into Northcentral Texas south into the Texas Hill Country. While these storms gradually weakened after daybre…

Flood insurance in Titus County

If a building in Titus County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
