How Montague County floods

Flash flooding from severe storms dominates the flood risk profile in Montague County, supported by 34 flash flood events compared to 9 general flood events over the last 30 years. Slow-moving fronts, upper-level troughs, and training thunderstorms frequently drive these localized hazards.

Recent events illustrate this pattern. On April 30, 2025, a slow-moving front and upper trough generated widespread showers and severe thunderstorms that caused significant flash flooding across the area. Earlier that month, on April 19, 2025, multiple upper-level shortwaves interacting with a cold front and dryline produced severe storms, flash flooding, and tornadoes.

National Flood Insurance Program claims data indicates that properties in FEMA Zone A experienced the highest volume of claims with 42 filings, averaging $18,679 per claim and an average recorded water depth of 6 inches. Zone X properties recorded 19 claims with an average payout of $31,616 and an average recorded water depth of 2 inches. Zone UNKNOWN recorded 11 claims with an average payout of $22,662 and an average recorded water depth of 5 inches, while Zone X_UNSHADED logged 5 claims averaging $11,321 with an average recorded water depth of 4 inches. Homeowners and real estate professionals in Zone A and unshaded or moderate-risk zones alike should pay close attention to these historical flood and payout patterns.

From the storm reports

Flash Flood · Apr 30, 2025. A slow moving front and an upper trough generated scattered thunderstorms on April 29, and widespread showers and thunderstorms on April 30, across much of North and Central Texas. Some of these storms became severe with large hail and damaging winds, but the most impactful weather was flash flooding due to the slow movement of the front and the resulting ���training��� of thunderstorms along and near…

Flood · Apr 20, 2025. Multiple upper level shortwaves moved overtop the Plains contributing to the development of severe storms near and along a cold front and dryline on and off between the 18th and 20th. Large hail, damaging winds, flash flooding, and tornadoes were all observed, particularly on the 19th. A total of 12 tornadoes occurred along and east of Highway 281 causing considerable damage: 1 EF-2, 5 EF-1s, and 6 EF-0s.

Flash Flood · Nov 8, 2024. An upper level storm system brough scattered strong to severe storms that produced large hail, wind damage, and flash flooding for areas near and west of I-35 on both the 7th and 8th. The largest observed hail was the size of golf balls and was reported in Young County.

The zones you’ll see on the map

Flood insurance in Montague County

If a building in Montague 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.
