Flash Flood · Jan 30, 2025. A slow moving upper low generated multiple rounds of rain, some heavy, the night of January 29 into the morning of January 30 across North Texas. Much of the heavy rain and associated flooding occurred in and near the DFW Metroplex.
Flash Flood · Apr 5, 2025. Multiple rounds of showers and storms occurred as a cold front moved through North Texas and stalled in East/Central Texas. These storms produced large hail, damaging winds, a tornado, lightning related damage, and flash flooding. The largest hail stone fell in Eastland County on the 3rd, with a diameter of 2.5 inches. A EF-0 tornado was found to have occurred in Van Zandt County on the 4th.
Flash Flood · Aug 13, 2017. An upper level disturbance kicked off multiple rounds of showers and thunderstorms along a stationary front which stretched across North Texas. A few severe storms occurred during the evening of Saturday August 12th, then training thunderstorms with heavy rain led to flash flooding in many locations between the Red River and the Interstate 20 corridor during the morning of the 13th.

A potent storm system brought deadly tornadoes and severe weather to North Texas on the 26th followed by waves of heavy rainfall that resulted in significant flooding across parts of North and Central Texas. Twelve tornadoes were confirmed on the afternoon and evening of the 26th, killing 13 and injuring over 300. The strongest tornado was an EF-4 that struck the Garland and Rowlett areas of Dallas and Rockwall C…

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 Delta 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.
