How Tyler County floods

Tyler County experiences a flood risk profile dominated by flash flooding from severe weather systems, accounting for 30 out of 39 recorded flood events over the last 30 years alongside 5 general floods, 2 tropical storms, and 2 hurricanes, resulting in 1 recorded flash flood death. Recent events illustrate this pattern, including severe thunderstorms and heavy rain in April 2024 that caused flooding in areas not yet drained from earlier in the month, as well as multi-day unsettled weather and squall lines producing flash floods in May 2024.

National Flood Insurance Program claims data demonstrate that flood risks extend across multiple zones. Zone A accounts for 98 claims with an average payout of $18,659 and an average recorded water depth of 4 inches. Properties designated as Zone X recorded 39 claims with an average payout of $40,110 and an average water depth of 8 inches, while unshaded Zone X properties saw 25 claims averaging $26,490 with an average water depth of 5 inches. Additionally, unknown zones logged 24 claims averaging $19,203 with an average water depth of 8 inches, and shaded Zone X recorded 1 claim with an average payout of $18,260 and 0 inches of recorded water depth.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located in high-risk Zone A, which holds the highest concentration of historical claims, as well as properties in Zone X and unshaded Zone X areas where lower-frequency events have resulted in higher average claim payouts and greater recorded water depths.

From the storm reports

Flash Flood · Apr 21, 2025. Slow moving thunderstorms affected southeast Texas as a cold front stalled across the region.

Flash Flood · Apr 29, 2024. A line of thunderstorms moved across Southeast Texas causing another round of heavy rain and severe weather. This produced more flooding in areas that had not completely drained from rain earlier in the month.

Flash Flood · May 16, 2024. An upper trough parked over the region for near a week. Short waves kept traversing the base of the trough for the duration of the event causing several days of unsettled weather. Some days produced severe squall lines with numerous reports of damage.

The zones you’ll see on the map

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

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.

Flood insurance in Tyler County

If a building in Tyler 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.
