Flash flooding and standard flooding from severe thunderstorms and tropical systems dominate the historical flood record in Crosby County. Over the past 30 years, the NOAA Storm Events Database recorded 10 flash flood events, 9 flood events, and 1 tropical depression.
Severe storms frequently trigger these conditions across the region. For example, a supercell thunderstorm produced widespread damage before weakening as it entered Crosby and Garza Counties in June 2025. Another severe storm event occurred on April 24, 2025, amid widespread thunderstorm activity driven by persistent southwesterly flow aloft and increased southeasterly winds. Additional severe thunderstorms developed along a dryline in May 2024.
Flood insurance claims data from FEMA indicates activity in lower-risk areas, with one recorded claim in Zone X averaging a payout of $32,519 and an average recorded water depth of 0 inches. Homeowners, real estate agents, and journalists should note that properties outside of traditional high-risk special flood hazard areas still experience recorded claims and should review local property risk profiles accordingly.

Flash Flood · Apr 24, 2025. Another day of widespread severe thunderstorms occurred on the afternoon and evening hours of the 24th. Persistent but weak southwesterly flow aloft increased on the 24th which allowed supercell thunderstorms to produce giant hail. Increased low level southeasterly winds also allowed these thunderstorms to produce numerous tornadoes. Thunderstorms initially developed late in the afternoon along a dryline along the…
Flash Flood · Jun 5, 2025. During the afternoon and evening hours of the fifth, an intense supercell thunderstorm moved over the South Plains region of West Texas, producing several tornadoes over portions of Cochran, Hockley, and Lubbock Counties. This thunderstorm also produced widespread damage from very strong straight-line winds and large hail across western and southwestern portions of the City of Lubbock (Lubbock County) before it ex…
Flash Flood · May 1, 2024. Numerous severe thunderstorms developed on the afternoon of the first in advance of a short wave trough moving across southern New Mexico and northern Chihuahua. A dryline initially positioned near the Texas/New Mexico state line early in the morning, mixed eastward through the day, settling along and just east of the Interstate 27/US Highway 87 corridor. Scattered thunderstorms initially developed along this dryl…
Flood · May 24, 2019. A persistent upper level trough over the western United States allowed for another day of convective development across the South Plains of West Texas. Although strong large scale lift was not anticipated on the afternoon of the 24th, widespread severe thunderstorms developed under a very moist and unstable atmosphere. A quasi-stationary warm front began to move northward during the morning hours with a dryline mi…

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Crosby 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.
